CEW Industry News Charging Stations for e-Vehicles Inaugurated in Dwarka

Anant G Geete inaugurating e-charging infrastructure in New Delhi

Union Minister of Heavy Industries & Public Enterprises,Anant G. Geeteinaugurated Charging Infrastructurein the premises ofDwarka metro station in New Delhi Charging Infrastructure has been developed

by Rajasthan Electronics & Instruments Ltd. (REIL) having 18 charging stations. Speaking on the occasion the Minister said 400 e-rickshaws may be charged from these stations free of cost. The Minister said that if sponsors are ready then charging will remain free of cost.

REIL has already set up 45 charging stations till datein different cities.

Department of Heavy Industry funds charging station installed by REIL. Earlier the Minister had launched 8 charging stations in the premises of Udyog Bhawan in New Delhi for facilitating charging of e-vehicles.

For reduction in pollution levels and making cities cleaner and environment friendly, the Government is working on FAME-II Scheme having focus on mass & shared public transportation based on electric powertrain. The necessity for development of charging infrastructure for smooth roll out of electric mobility in the country is being addressed in the Phase-II of FAME Scheme. The Department has notified FAME India Scheme in the year 2015 under National Electric Mobility Mission Plan of the Government.

The Phase-1 of this scheme is being implemented through four focus areas namely Demand Creation, Pilot Projects, Charging Infrastructure and Technology Platform and R&D. Under Demand Creation component of the scheme, incentive is available to buyers of electric and hybrid vehicles (xEVs) in the form of an upfront reduced purchase price to enable wider adoption. Managing Director, Delhi Metro Rail Corporation was also present on this occasion.

About 10,000 CNG stations to be in place; Bio-ATF and Bio-CNG policies to be formulated The Union Minister of Petroleum and Natural Gas & Skill Development and Entrepreneurship Dharmendra Pradhan has emphasized on a clean, efficient and affordable mobility system. In his opening remarks at the Global Mobility Summit 2018, he said that despite changing global trends, consumption of petrol and diesel in India is growing in excess of 5% per annum. Whatever be the scenario of the growth of Electric vehicles, India would still need higher refining capacities. To achieve cleaner emissions, the Minister added, India will leapfrog from BS-IV to BS-VI standards, and the NCT of Delhi has already switched to the better fuel since April this year. Pradhan said the Government has already implemented fuel efficiency norms for commercial heavy vehicles.

Talking about the gas based transportation solutions, the Minister said that the use of CNG, LNG and Bio-CNG is being promoted in the sector, and there are plans in place to have about 10,000 CNG stations within a decade, covering over half of the country. On the issue of promoting LNG as a fuel for long distance transportation by heavy commercial vehicles, Pradhan informed about the efforts being made by Public sector oil companies and some private enterprises in setting up LNG distribution infrastructure. He 6 • September 2018

said that 12 bio-refineries are being set up and steps are being taken to achieve 10% ethanol blending. Soon, Bio-ATF and Bio-CNG policies will be formulated. Indian Oil has tied up with the Delhi Government to introduce 50 Hydrogen enriched CNG buses next year. On the issue of Electric Vehicles, Pradhan said that there are challenges concerning setting up of infrastructure and economy of converting to EVs, and Interministerial teams are working to put in place a comprehensive policy on the matter. In the session, Graham Stuart, Parliamentary Under Secretary of State, UK, Dr Lam Pin Min, Senior Minister for Health and Transport, Singapore and Mrs Sindisiwe Chikunga, Deputy Minister of Transport, South Africa also participated. All of them outlined the trends and developments in the mobility sector in their respective countries.

Stuart appreciated the Indian Government’s efforts to provide LPG and Electricity to a large number of citizens.

Cabinet approves on Fixation/Revision of ethanol price The Cabinet Committee on Economic Affairs, chaired by the Prime Minister Narendra Modi has given its approval to revise / fix the price of ethanol derived from B heavy molasses / partial sugarcane juice and fix a higher price for 100% sugarcane juice based ethanol for the forthcoming sugar season 2018-19 during ethanol supply year from 1st December 2018 to 30th November 2019. The decision will serve multiple purposes of reducing excess sugar in the country, increasing liquidity with the sugar mills for settling cane farmer's dues and making higher ethanol available for Ethanol Blended Petrol (EBP) Programme. All distilleries will be able to take benefit of the scheme and large number of them are expected to supply ethanol for the EBP programme. Remunerative price to ethanol suppliers will help in reduction of cane farmer's arrears, in the process contributing to minimizing difficulty of sugarcane farmers. Ethanol availability for EBP Programme is expected to increase significantly due to higher price being offered for procurement of ethanol from B heavy molasses / partial sugarcane juice and 100% sugarcane juice the for first time.Increased ethanol blending in petrol has many benefits including reduction in import dependency, support to agricultural sector, more environmental friendly fuel, lesser pollution and additional income to farmers. Ethanol Blended Petrol Programme was launched by the Government in 2003 on pilot basis which has been subsequently extended to the Notified 21 States and 4 Union-Territories to promote the use of alternative and environment friendly fuels. This intervention also seeks to reduce import dependence for energy requirements and give boost to agriculture sector.

Government has notified administered price of, ethanol since 2014. This decision has significantly improved the supply of ethanol during the past four years. The ethanol procured by Public Sector OMCs has increased from 38 crore litre in ethanol supply year 2013-14 to estimated 140 crore litre in 2017-18. Consistent surplus of sugar production is depressing sugar price. Consequently, sugarcane farmer's dues have increased due to lower capability of sugar industry to pay the farmers. Government has taken many decisions for reduction of cane farmer's dues.

With a view to limit sugar production in the Country, Government has taken multiple steps including, allowing diversion of B heavy molasses / sugarcane juice for production of ethanol. As the ex-mill price of sugar has increased from the earlier estimated price, there is a need to revise price of B heavy molasses / partial sugarcane juice and 100% sugarcane juice for production of ethanol. It is worth noting that as compared to ethanol derived from C heavy molasses route, diversion of B heavy molasses reduces the sugar by about 20% and increases ethanol availability by about 100%. On the other hand, diversion of sugarcane juice reduces sugar by 100% and increases ethanol availability by about 600%.

The Minister also invited the industry representatives to join hands with the Government on various initiatives such as air pollution control, waste management river conservation, or biodiversity conservation.

Speaking on the occasion, Minister of State (Independent Charge) of Housing and Urban Development, Mr. Hardeep Singh Puri said, “India’s development trajectory will be ‘green’ and in consonance with the ethos of the 2030 development agenda”. He stated that India stands united in its efforts against rising global temperatures and elaborated that a quick glance at India’s Intended Nationally Determined Contributions reaffirm this point and referred to the target of 175 GW renewable energy capacities by 2022 as unprecedented. He averred that the adoption of the Sustainable Development Goals in 2015 recognized the intrinsic linkages between climate change and urbanization. “Goal 11, titled “Make cities and human settlements inclusive, safe, resilient and sustainable” has embedded in it, critical elements of climate action. Solid waste management, air pollution, slum housing, and water related disasters, are just some of the climaterelated aspects covered in Goal 11”, he outlined. Pointing to the objective of the Swacch Bharat Mission (SBM) to make India ODF and have 100% scientific solid waste management by October 2, 2019, the Minister suggested that SBM is not only about infrastructure, but also bringing about behavioural and cultural changes among citizens. He added that to ensure India’s city driven development is sustainable, the government has embarked on the world’s largest planned urbanization programme.

The key to the process is “integration”, meaning all policies, projects, and proposals are considered in relation to one another, he added.

Puri stated that the use of new and alternate construction technologies in the construction of houses, locally available eco-friendly materials suited to local climatic conditions are being encouraged, reducing not only the cost of construction but also the resultant carbon footprint. He also emphasised on affordable, eco-friendly and modern urban transportation services and said that Delhi Metro is today comparable to the best in the world.

Director General, Confederation of Indian Industry (CII), Mr. Chandrajit Banerjee, European Commissioner, Mr. Karmenu Vella and representatives from industry and civil society were among those present on the occasion.

CEW Industry News Haldor Topsoe invests in Indian fertilizer plant Topsoe, IFU, and DAF have signed a shareholder agreement with promoter companies National Fertilizers Limited (NFL), Engineers India Limited (EIL), Fertilizer Corporation of India Limited (FCIL), the natural gas processing and distribution company GAIL, and the State of Telangana. The partners have agreed on a shared investment in the Ramagundam fertilizer plant, which is scheduled to begin operation in the second quarter of 2019 as the first of the revival projects.

“We see Topsoe and IFU’s investment as a very important aspect of the financial closure and as a sign of their confidence in the project management team and fundamental parameters of the venture. It brings about a tangible support from Topsoe in terms of future operational efficiencies, optimal energy efficiency, and back-end support from the world’s leading ammonia technology supplier. In addition, we expect that the international experts from Topsoe and IFU on the Board of Directors of RFCL will pave the path for good corporate governance as well as technical vision for our future direction,” says V. K. Malhotra, CEO, Ramagundam Fertilizer. Topsoe’s uninterrupted dedication to the Indian fertilizer industry for more than five decades has made the company the largest supplier of process and catalyst solutions in the Indian market.

“Topsoe has a long-standing presence in India where our world-leading ammonia technologies have been instrumental in building a domestic Fertilizer industry. Today, we are proud to expand our engagement in the revival process by becoming an active investor in the Ramagundam plant together with our extremely competent Indian and Danish partners. This is yet another important step in the Indian government’s efforts towards self-sufficiency in urea production and as a consequence: food security,” says Amy Hebert, Executive Vice President and Deputy CEO, Topsoe.

The Indian fertilizer sector consists mainly of publicly owned companies, and foreign direct investment in the sector is not customary. However, Topsoe is now a member of the group of owners of the Ramagundam plant because of the important role of Topsoe’s ammonia technologies and catalysts in the plant. Topsoe and its Danish partners will have a seat in the Board of Directors of the Ramagundam plant and will take an active role to secure long-term success.

CEW Industry News Linde-Praxair merger receives conditional clearance The Competition Commission of India (CCI) has approved the combination of Linde Aktiengesellschaft and Praxair Inc. The approval is, however, subject to the condition that the parties divest their current shareholdings in companies in India that may impact competition.

German company Linde and US-based Praxair manufacture and supply industrial, medical and specialty gases. In addition, Linde operates in the related engineering and services sectors. In India, it has a joint venture with Inox Air Products Ltd. Praxair has an Indian unit.

“The proposed combination is likely to have an appreciable adverse effect on competition in some markets in India but the same could be addressed by way of modifications to the proposed combination,” said CCI in a statement.

U.S. Chemical Industry Investment Linked To Shale Gas Reaches USD 200 Billion The American Chemistry Council (ACC) has announced that U.S. chemical and plastics industry investment linked to plentiful and affordable domestic supplies of natural gas and natural gas liquids (NGLs) from shale formations has surpassed USD 200 billion. Since 2010, 333 chemical industry projects cumulatively valued at USD 202.4 billion have been announced, with 53 percent of the investment completed or under construction and 41 percent in the planning phase. Fully 68 percent of the total is foreign direct investment or includes a foreign partner. Project types include new facilities and capacity expansions.

"This is an exciting milestone for American chemistry and further evidence that shale gas is a powerful engine of manufacturing growth," said ACC President and CEO Cal Dooley. "The U.S. remains the most attractive place in the world to invest in chemical manufacturing. We look forward to continuing to transform energy into a stronger economy and new jobs."

ACC analysis shows that USD 202.4 billion in capital spending could lead to USD292 billion per year in new chemical and plastics industry output and support 786,000 jobs across the economy by 2025.

These include 79,000 chemical industry jobs, 352,000 jobs in supplier industries, and 355,000 jobs in communities where workers spend their wages. Additional, temporary jobs are created during the capital investment phase. Robust supplies of NGLs, especially ethane, are key to the U.S. chemical industry's competitiveness. NGLs are the main feedstock for basic petrochemicals and plastics in the United States, while companies overseas mostly use naphtha, which is oil-based. Since feedstock comprises about 75 percent of the cost of ethylene production, lower prices favour U.S. chemical makers in global markets.

A note of caution is in order. U.S. manufacturers often rely on inputs that are not available or made in the U.S. to create products that cost less, yet perform at the high level our downstream customers have come to expect from us. Protectionist trade policies such as tariffs and quotas unnecessarily raise the costs of those inputs, deter innovation and economic growth, and could ultimately weaken our country's competitive advantage.

Today's announcement provides another update to ACC's first report, "Shale Gas, Competitiveness, and New U.S. Chemical Industry Investment – An Analysis of Announced Projects." Released in May 2013, the report analyzed 97 chemical and plastics industry projects totaling USD72 billion in potential investment that had been announced as of March 2013. As new projects are announced, we update our tally of announced projects and cumulative investment.

ACC analysis employs the IMPLAN input-output methodology, an economic model that quantifies interdependencies among industries or economic sectors. IMPLAN is used by government agencies including the Army Corp of Engineers, U.S. Department of Defense, U.S. Environmental Protection Agency, and over 20 others, and by over 250 colleges and universities, local governments, non-profits, consulting companies, and other private sector companies.

ExxonMobil Signs Framework Agreement for Proposed Chemical Complex in China Exxon Mobil has signed a cooperation framework agreement with the Guangdong Provincial People’s Government to advance discussions concerning the proposed construction of a chemical complex in the Huizhou Dayawan Petrochemical Industrial Park. The new facility would help meet expected demand growth for chemical products in China.

The multibillion-dollar project, which remains subject to a final investment decision, would include a 1.2 million-tons-per-year ethylene flexible feed steam cracker, two performance polyethylene lines and two differentiated performance polypropylene lines. ExxonMobil’s decision to proceed with the project will be based on a number of factors, including receipt of permits and project competitiveness. Startup is planned for 2023.

“Our agreement with the Guangdong Provincial Government demonstrates ExxonMobil’s interest in advancing this project from concept to completion,” said John Verity, president of the ExxonMobil Chemical Company. “We value the government’s support and its experience in moving such a large-scale project forward.”

The new complex would rely on advanced proprietary technologies in direct crude steam cracking and performance polymers manufacturing. It would support progress toward China’s national petrochemical development priorities, which include self-sufficiency, diversified feedstock sources, rebalancing fuels versus chemicals and advancing new competitive technology. The framework agreement also confirms Guangdong Province’s support in progressing the Huizhou LNG receiving terminal, in which ExxonMobil intends to participate, including supply of LNG. The company is also evaluating other chemicals manufacturing projects in Asia to help meet expected demand growth in the region. ExxonMobil expects to grow chemicals manufacturing capacity in Asia Pacific and North America by about 40 percent. That growth will be achieved in part by adding 13 new facilities, including two world-class steam crackers in the United States that are part of the company’s Growing the Gulf initiative.

These investments would enable the company to meet increasing demand in Asia and other growing markets.

The company recently commenced operations at its new 1.5 million tonper-year ethane cracker at the company’s integrated Baytown chemical and refining complex in Texas. ExxonMobil and SABIC have also created a new joint venture to advance development of the Gulf Coast Growth Ventures project, a 1.8 million tonne ethane cracker currently planned for construction in San Patricio County, Texas. The facility will also include a monoethylene glycol unit and two polyethylene units.

ExxonMobil’s downstream and chemical businesses both have a presence in China, and the company operates primarily through its Shanghai-based ExxonMobil (China) Investment Co. Ltd. affiliate. The company is also a joint venture partner with Sinopec, Fujian Province and Saudi Aramco in China’s first integrated refining and petrochemical facility to include international participation. ExxonMobil is committed to social investment where it operates and supports programs that focus on the environment, health and education.

CEW Industry News Lanxess Increases production line for corrosion inhibiting additives

Specialty Chemicals Company LANXESS has commissioned a new production line at its Mannheim site for the synthesis of dimercaptothiadiazole (DMTD) derivatives. These chemicals are added to lubricants as multifunctional additives. The production line, which started in May 2018, doubles the annual production capacity of these specialty additives. The investment volume is in the single-digit-million-euro range.

“With this investment, we have responded to the increased customer demand for these specialties. The new plant will enable us to meet their requirements for high-quality lubricant additives, but also helps us acquire new customers, and further develop our own package solutions for a rapidly growing market,” says Dr. Martin Säwe, Head of the Lubricant Additives business line in LANXESS’s Additives (ADD) business unit.

DMTD derivatives are multifunctional additives, and are initially used as corrosion protection for lubricants in contact with steel alloys containing so-called nonferrous metals such as copper, nickel or cobalt. They prevent the leaching of nonferrous metal ions from the alloy, protect the metal surface from aggressive chemicals, and thus guarantee the integrity and longevity of steel alloys. Thanks to their metal-surface bond, they also act as lubricants, even when under extreme conditions and high pressures metal surfaces start contacting each other. Therefore, and in addition to their function – that is, to provide protection against corrosion, they are also referred to as extreme pressure additives. Last but not least, these additives interact with and absorb aggressive chemical breakdown products in the lubricant, which could otherwise cause material damage in the long term. The main areas of application for these versatile products are industrial oils, greases, and metalworking fluids.

Under the Additin brand name, ADD supplies customers worldwide with DMTD derivatives, which are also used in additive packages at LANXESS. Due to a special manufacturing process used to reach the optimal composition, their performance is both excellent and consistent.

Compared to competitor products, the additives stand out due to their stable quality and performance, a mild odor, and their bright, clear appearance. The products are manufactured exclusively at the site in Mannheim.

Clariant, a world leader in specialty chemicals, today announced an updated strategy and financial outlook as well as the signing of a Memorandum of Understanding with SABIC on a significant collaboration opportunity between the two companies in the area of high performance materials. The Group intends to expand more strongly by focusing on customer-specific products and solution offerings with attractive growth prospects and above average value potential. By 2021, following the creation of High Performance Materials and the divestment of the remaining Plastics & Coatings Business Area, Clariant expects to deliver significantly higher sales of around CHF 9 billion and an EBITDA margin of approximately 20 % with an operating cash flow of more than CHF 1.2 billion.

“The portfolio upgrade together with the continuation of Clariant’s strategy enables the Group to realize a significant step change into higher value specialties, which will allow the Group to considerably augment value creation for all our stakeholders”, said Hariolf Kottmann, CEO of Clariant. The intended combination of Clariant’s Additives and high value Masterbatches (color, high temperature resins and health care) and parts of SABIC’s Specialties business will create a uniquely positioned provider of highly customer-specific high performance materials and solutions under the name High Performance Materials.

This new Business Area will offer a customer-specific, application know-how driven and competitively advantaged product range of highperformance thermoplastics for demanding thermo-electro-optical and mechanical environments, specialty additives and masterbatches in tandem with an outstanding global compounding platform. Major applications include smart electronics, health care, aerospace, automotive, robotics, additive manufacturing, renewable energy, and e-mobility. These applications demand the fulfillment of stringent customer specifications which require exclusive technology and formulation know-how.

The combination of Clariant’s and SABIC’s offerings within Clariant is expected to result in significant synergies with an anticipated annual run-rate of CHF 100 million, realized over three years from closing.

Implementation costs are estimated at CHF 80 million over the same time. The combination will be significantly EPS accretive in the first year.

Clariant will have the majority stake in the intended business combination.

Depending on the definitive valuation which is to be determined by both parties in the coming months, an equalization consideration will be made

by Clariant to SABIC. In addition, Clariant announced that by 2020 it intends to divest the Pigments, standard Masterbatches and Medical Specialties businesses which will not be included in the newly formed Business Area High Performance Materials. This divestment decision underlines Clariant’s commitment to move the portfolio into higher specialty areas and to ensure best ownership for each of its businesses. Despite being well positioned and having significantly increased their profitability over the past years, the businesses to be divested do not match the Group’s criteria to differentiate through innovation in higher growth and higher profitability areas.

By 2021, following the creation of High Performance Materials and the divestment of the remaining Plastics & Coatings Business Area, Clariant expects to deliver significantly higher sales of around CHF 9 billion and an EBITDA margin of approximately 20 % with an operating cash flow of more than CHF 1.2 billion.

Energy Conservation through Proper Condensate Recovery Increasing fuel cost have led to increase in steam cost, which is an area of concern for the process industry.

Most chemical plants have adopted energy savings measures to optimise their fuel consumption in boilers.

Article offers recommendations to reduce energy bills through effective condensate evacuation and maximising Condensate Recovery Factor (CRF).

S

team has been used as a working fluid or utility media throughout industry not only for mechanical power production (ie, driving steam turbines to produce electrical power) but also for many space heating and process applications. The advantage of using steam as the working fluid is due to the ease of distribution and control. Fuel prices across the world are on the rise which has resulted in an increase in steam cost and hence an area of concern for the process industry.

Most chemical plants have adopted energy savings measures to optimise their fuel consumption in boilers. This ensures the best steam cost in day to day operation of their steam boilers. In a typical process plant, the boiler generates steam to meet the steam demand of the process. Any optimisation in the steam utilisation leads to reduction in the steam generated. Thus, optimum steam utilisation for the process direct impacts the annual fuel bill.

The chart below indicates the spiralling cost of solid fuel price used for steam generation in the span of 10 years - ` 2.8/kg to ` 6.2/kg (CAGR of 8.27 per cent, ahead of inflation in most years) For optimising the annual fuel bill it is recommended to focus on the following two broad categories: 1. Effective condensate evacuation by selecting the correct type of steam trap along with the essential accessories 22 • September 2018

When steam transfers its heat to any process, it is the enthalpy of evaporation, which is transferred first, and the steam thus condenses back into water at the same temperature. Steam utilisation and condensate management, in a proper engineered way, plays a crucial role in bringing down operational costs. This directly impacts the revenue savings for the industry and thus become the need of the hour.

• Rugged construction for least maintenance costs • Robust internals for delivering high up-time In the industry, very often the procurement of steam traps is based on the lowest cost and not on the overall cost of ownership. The total cost of the steam trap should include tangible incidental costs, such as piping cost, steam loss through the failed trap or the steam loss due to the bypass valve kept cracked open, reduced production output, loss of production due to frequent downtime. Taking such factors into consideration such as, reduction in the overall cost of installation, operation and maintenance is critical.

2. Benefits of Condensate Recovery

2. Maximising Condensate Recovery Factor (CRF), ratio of condensate recovered to the total steam generated 1. Proper Selection of Process Steam Trap – Effective Condensate Evacuation A fundamental step for ensuring optimum steam consumption for any process application is to ensure selection of right type of steam trap. Proper selection of steam trap must consider many factors; a few of them are listed below: • Quick plant start up with continuous venting of air and incondensable gases • No tolerance for loss of steam under all operating conditions • Efficient temperature control / steam consumption through effective condensate discharge • Self-draining to prevent damage from freezing during plant shutdown • No disruption of operation if the trap fails • “All-in-one design,” with a strainer, check valve and air vent

When steam heats the process liquid, around 75 per cent of its energy is transferred to process and steam condenses. Balance 25 per cent energy is held by the condensed water.

The condensate is pure water, having almost zero TDS, which is ideal to be used as boiler feed water. Since it is at a higher temperature, less fuel will be required to produce steam.

Every 6 Degree Celsius rise in feed water temperature saves 1 per cent on the fuel bill.

In a nutshell, the advantages of condensate recovery would be 1. Elevated boiler feed water temperatures 2. DM quality water 3. Minimises the amount of chemicals required to treat boiler feed water 4. Minimises water usage that is critical in most geographical locations 5. Effective return can lower load on cooling tower, overall costs thus positively influencing profitability 6. Addresses environmental concerns, norms (Zero Liquid Discharge) In the chemical industry, one of the major concerns for condensate recovery is the fear of contamination.

Multi Utility Reactors ( MURs) The optimisation of above processes is mainly achieved with 1. Correct process temperature control – PID based instead of On-Off control valves 2. Optimised steam condensate evacuation systems (evacuation of condensate even under stall conditions) 3. Segregation and recovery of pure steam condensate from Multi Utility Reactors These solutions have been implemented at a major chemical plant in Vishakhapatnam, and results are close to ideal.

Section-wise challenges and solutions MEE Challenge • Steam condensate evacuation issues from Agitated Thin Film Dryer (ATFD) due to group-trapping • Stripper condensate evacuation issue thereby requiring the bypass valves to be always kept cracked open (due to stalling) • Huge wastage of flash steam from this section Solution • To save the cost of additional steam traps and related installation and maintenance issues, a single steam trap is used to drain condensate from the multiple sections of the ATFD. This practice is commonly termed as “group trapping”.

On the face of it, this sounds perfect as due to common pressure, chances of water logging are eliminated. In reality, no two coils or heat exchangers are identical. Even though the pressure at which steam is received by both heat exchangers is same, the heating loads will vary differently. As a result, the 24 • September 2018

Case Study: Proper monitoring and control of process parameters in the following major areas of steam consumption in a chemical plant facilitates energy savings:

pressure difference will come in the picture and the section at low pressure will be unable to discharge. Along with this, the pressuredrop taking place across each of the heat exchangers will be different. Pressure drop taking place in a heat exchanger depends of a large number of parameters like: fouling factor, process temperature profile, ambient temperature ,etc. It is quite clear that all these parameters are beyond manual control and if group trapping is done, it will result in issues like water logging and damage to the equipment. Installation of correct size and type of individual process trap for draining condensate from each section of ATFD instead of group trapping.

• “Stall” is the reduction or the cessation of condensate flow from the steam space, and occurs when the pressure in the steam space is equal to, or less than, the total backpressure acting on the steam trap.

Stripper condensate evacuation was optimised by installing a process trap that can evacuate condensate even under negative differential pressure thus optimising removal of condensate.

• Closed loop condensate management system such that the flash steam from ATFD is recovered in the Stripper and the condensate is then recovered at elevated temperature ( >100o Celsius).

Modern day solutions help in recovering the effective heat from contaminated condensate, thus enabling optimised condensate recovery factor.

CONDENSATE RECOVERY FACTORS ( CRF)

Addressing the issues mentioned above led to a 18 per cent increase in condensate recovery and direct saving of 7 per cent in the annual fuel bill.

The benefits of modern day energy conservation methods are now being realised, and slowly but surely replacing traditional methods in the chemical industry. This not only will help the plants attain their energy conservation goals and reduce their carbon footprint, but also contribute to a healthy bottom line that is crucial to stay ahead in a competitive market place.

Solution • Installation of adequately sized PIDbased temperature control valves with proper position indicator indicating the percentage of opening under varying load conditions.

• Stripper condensate evacuation optimised by installing a process trap that can evacuate condensate even under negative differential pressure thus optimising removal of condensate.

Pollution Control Techniques in Refinery and Downstream Petrochemical Plants Pollution is a universal problem that intensifies with each passing day due to growing population and pollution of surface & ground water sources. Indiscriminate industrial development and exploitation of limited water sources are compelling every industry to seriously address this problem. Besides this, availability of water has become a serious issue. Therefore, industries are considering various options to reduce their water usage and to recycle water to the extent possible along with adopting manufacturing technologies that require less water, produce minimum waste water as well as other solid & liquid waste. Increasing cost of water and stringent regulations have helped make water recycle a viable option. This article deliberates on the topics of recycle, zero liquid discharge and solid waste management and explores their various technologies.

P

revention is better than cure. This also applies to pollution. Prevention or minimisation of pollution at source is the best control method.

Hence, before going into the methods of effluent treatment, we should look at the possibilities of preventing or minimising effluent generation. Pollution prevention is defined as the use of materials, processes or practices that reduce or eliminate the generation of pollutants or wastes at the source. Also known as reduction at source, pollution prevention includes practices that reduce the use of hazardous and non-hazardous materials, energy, water or other natural resources. Pollution prevention in the manufacturing industry can be achieved by changing production processes to reduce or eliminate the generation of waste at the source. As it applies to industry, the environmental management hierarchy stipulates that when possible:

• Pollution should be reduced at the source • Pollution products that cannot be reduced should be recycled in an environmentally safe manner • Disposal into the environment should

be used only as a last resort and should be conducted in an environmentally safe manner Recycle of Waste Water and Study of its Application in Various Industries Waste water recycle should take shape at the drawing board stage in contrast to the conventional treatment approach of designing the raw water and waste water treatment plants (end of pipe solutions) separately. This will enable planning for water recycle at the design stage itself.

The benefits are many.

Firstly, because water is recycled, raw water consumption reduces. The designer can therefore plan for a raw water treatment plant of lower capacity and cost.

Secondly, the effluent treatment plant’s capacity is also reduced as we are treating the effluent which is not being recycled and hence the quantity of waste disposed is less, leading to further cost reduction.

Investment is certainly required for product recovery, water recycle plants and advanced technologies to handle even higher concentrations of contaminants.

Treated Water

Process

Effluent

However, the life cycle and return on investment is quite attractive.

Pollution is not just abated but prevented; pollutants are separated not destroyed; energy is saved and the total cost of water and waste water treatment is reduced.

Hence, we can use this experience of on/ offsite recycle and integrated solutions for water and waste water treatment in large industries to achieve the goal of ‘Total Water Management’ at the design stage.

We need to only apply these approaches in a complex industry in multiple ways.

Guidelines for Selection of Recycle Scheme 1. Study the manufacturing process thoroughly and identify areas where reduction of water consumption is possible.

2. Identify the process where reduction of pollution load is possible by changing raw material or adopting cleaner manufacturing process.

3. Proper analysis of various streams especially targeting the contaminants which are process specific.

4. Identify streams that can be segregated and treated economically.

For example, in electroplating, the rinsed water can be segregated and treated for recovery of plating metal.

This not only reduces the overall cost of recycle but also facilitates the recovery of valuable products from the waste water stream.

5. Identify effluents which are relatively clean and can be treated with simple processes so that they can be recycled internally without letting the water out into an effluent treatment plant.

6. Identify the quality of water required at various manufacturing stages.

For instance, steam generation may require high quality water and washing or cooling water make up may not require high quality water.

It is always economical to design a recycle system to produce water suitable for lower end usage.

7. Select a technology that is easy to implement, operate, maintain & service.

8. Look for the availability of spare parts that may be needed in the future.

9. Reliability of performance in the long run is extremely important.

Recycle Technologies Any waste water recycling plant requires four stages of treatment as follows: 1. Effluent treatment 2. Tertiary treatment 3. Advanced tertiary treatment 4. Zero liquid discharge Effluent Treatment For a good effluent recycle system, a good effluent treatment is a pre-requisite. Unless we remove the easily removable pollutants with cost-effective methods, it would be difficult to recycle the effluents economically.

Usually effluent treatment plants (ETPs) are designed to meet statutory requirements for disposal. When recycling is considered, the ETP should also be designed considering overall requirements of treatment. For example, in India, disposal standards do not require complete removal of nutrients and dissolved salts. But, when we are installing a downstream reverse osmosis system, it is better to remove nutrients and dissolved salts in the biological system of the ETP. This will help reduce fouling of the reverse osmosis system.

There are different technologies available for effluent treatment to remove different pollutants. Table 1 lists some generic technologies applied in effluent treatment.

Tertiary Treatment Treatment beyond disposal norms for reusing effluents for low end usages is called tertiary treatment. It acts as pretreatment to advanced treatment for complete recycle of effluents. Table 2 enlists some generic technologies applied in tertiary treatment.

Advanced Tertiary Treatment Further treatment of secondary treated effluents is required for conforming to the requirements of high end usages (boiler feed, process, etc.) of treated water.

Table 3 enlists some of the technologies available to remove various pollutants in advanced treatment: There are various other technologies which are contaminant and end use specific such as fluoride removal.

Zero Liquid Discharge Treatment (Evaporation and recovery of waste water containing highly soluble salts) The highly concentrated reject from the process is further treated in multi effect evaporator (MEE) system generally after reducing dissolved salts by RO processes and the advanced tertiary treatment.

Each of the above streams employs identical equipment for treating effluents, namely:

project, a new effluent treatment plant (ETP-III) treats effluents generated from the refinery project to meet the MINAS standard. With a view to conserving water, a new zero discharge plant (ZDP) was designed and constructed

by Ion Exchange. This plant treats the treated water from ETP-III to enable use of the treated water as make - up to the demineralisation plant. The capacity of the ZDP is 200 m 3/h. The plant was commissioned in 2005 and is operated and maintained

Challenges in Setting Up ETP For Refineries Petroleum refining is a complex operation and unit operations within refineries vary depending on the type of crude and the type of end products. Refining is a water intensive operation which generates large quantity of waste water that needs to be treated so as to avoid environmental degradation. A proper understanding of the unit operations as well as pollutant loads is necessary in order to set up a suitable Effluent Treatment Plant (ETP). This article discusses about various challenges that we have faced in the designing and operating of several Refinery ETPs in India.

C

haracterisation Of Waste Water In order to design an ETP for an upcoming refinery, design parameters like the flow rate, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Suspended Solids (SS), Oil & Grease (O&G), Sulfides, Phenols, Ammonia etc., have to be assumed.

The selection of the scheme and the estimation of unit sizes depend on the inlet characteristics and hence it is imperative that the assumed design parameters be as close to the actual parameters that will be encountered once the plant is commissioned. It is quite normal to assume higher values while designing the plants.

However, one should keep in mind that some processes do not perform efficiently when they are over designed.

separator followed by a Dissolved Air Flotation (DAF) or Induced Air Flotation (IAF) unit.

• Flow Equalisation: Flow of wastewater generated from refinery from various manufacturing process units is not uniform. The flow variation is equalised by providing an equalisation tank of sufficient capacity and constant flow is maintained in all downstream treatment units. This makes the process control much easier.

• Removal of Suspended Solids: This is achieved using a clarifier or it can be combined with O&G removal in a DAF unit

Typical Treatment Scheme The treatment philosophy adopted to treat refinery waste waters consists of a series of steps to sequentially remove the pollutants so that the treated wastewater meets the required regulatory norms. The typical treatment steps are:

• Removal of Sulphides: Lower sulphide concentration can be handled in biological treatment system. However, high concentrations of sulphides need to be taken care before wastewater enters into biological treatment system.

Oxidation of sulphides using Hydrogen Peroxide is most popular method of oxidising them.

• Removal of O&G: This is necessary as downstream operations are sensitive to the presence of high levels of O&G. In a refinery wastewater treatment system, two steps of oil removal are typically required to achieve the necessary removal of free oil from the collected wastewater prior to feeding it to a biological system. This oil removal is achieved by using an American Petroleum Institute (API) or Tilted Plate Interceptor (TPI) or equivalent oil water

Various • Biological Treatment: biological systems have been adopted including Activated Sludge Process, Bio-tower, Sequential Batch Reactor, Anaerobic reactors, Membrane Bioreactors etc. Every process has its own inherent advantages and disadvantages and a suitable system has to be selected by the designer based on factors such as organic load, treatment efficiency required, land area available etc.

40 • September 2018

• Polishing of Treated Waste Water This step includes units like Pressure Sand Filters (PSF), Dual Media Filters (DMF), Activated Carbon Filter (ACF) to remove the residual suspended solids as well organic pollutants that have passed through the earlier treatment steps.

• Reuse and Recycle : As the refinery consumes a large quantities of water, it is imperative one must try and reuse the treated waste waters back in the process. Additional treatment units like Microfiltration, Ultrafiltration or Reverse Osmosis may be adopted in order to meet the reuse water quality that is required Challenges and Solutions in Biological Treatment of Refinery Wastewater The key treatment step in the refinery ETP is the biological treatment as the bulk of the pollutants are removed in a cost effective manner in this step. Hence it is important to design this system in a robust manner so that it can operate efficiently. It is important to note that in the biological treatment step, the pollutants are degraded by microorganisms and it is imperative that a conducive environment is maintained such that the microorganisms can operate up to their maximum potential. A list of various factors that influence the design and operation of the biological system are given below: • Fluctuation of Wastewater Characteristics: One of the main challenges in refinery wastewater treatment is its variation in characteristics.

Figure2: Typical Refinery ETP

pollutant load for design of the ETP, it is normal to assume higher values so that the designs are ‘safe’. This causes problems during the operation of the ETP when the actual pollutant load is much lower.

Also, based on variations in quality of crude and refining process, wastewater quality also varies. The biological system should be selected to take care of these variations. The biological system should be able to vary process parameters such as air supply, Mixed Liquor Suspended Solids (MLSS), Food to Microorganism (F/M) ratio, etc., to suit variations in feed.

Modular design of biological process also helps in handling variations of wastewater quality. If provided with multiple process tanks, plant can be operated based on the actual pollution load by using all process tanks or part of them.

• Oil & Grease: The performance of the O&G removal equipment is sometimes upset due to a surge in the inlet O&G quantity due to dumping of oil within the refinery. This causes O&G to slip into the biological system affecting the microorganisms. This also causes foaming in the aeration tanks that affects the quality of the treated water. A figure showing the foaming 42 • September 2018

• Sulphides: Refinery wastewaters contain high levels of Sulphides that are toxic to microbes and hence have to be removed prior to the biological treatment.

In case sulphides slip into the biological system, it exerts demand on the aeration system since it consumes the oxygen that is meant for the respiration of the microorganisms. Hence it is normal to consider a safety margin in the design of the air blowers so that it can meet any contingency due to sudden air demand because of sulphides. Care should be taken that sulphide concentration in biological system are below toxic limits.

• Complex Organic Compounds and Heavy Metals: Complex organic compounds such as phenols, benzene products, etc. are also part of refinery wastewater. Their concentrations depend on the source and quality of crude oil. These compounds are not easily biodegradable and may be toxic to biological system at higher concentrations.

Hence, the ETP should be designed to handle these complex organics in case they are present in wastewater. Heavy metals also pose problem to biological treatment.

Both complex organics and heavy metals should be taken care in pretreatment if present in higher concentrations.

• Nutrients: The growth and performance of the microorganisms depend on the availability of critical nutrients like nitrogen and phosphorous in the waste water.

Ideally, a BOD:N:P ratio of 100:5:1 is required for best performance. Normally abundant nitrogen is present in the refinery wastewater. However, it is important to constantly analyse the wastewater and add nitrogen (typically as Urea) and phosphorous (as Phosphoric acid or Di Ammonium Phosphate) to make up for any deficit.

Many a times, total nitrogen levels in the wastewater are much more than required which necessitates treatment to reduce them. Hence, the biological system selected should be able to remove excess nitrogen along with organic pollutants.

• Energy efficiency: The oxygen required for the microorganisms are delivered through fine bubble diffusers that release small bubbles of air from the bottom of the aeration basins. Air blowers are installed to supply air into biological process. Air blowers constitute major portion of power consumption in the ETP. Any steps taken to optimise energy consumption shall result in energy efficiency of the plant.

Biological process should be provided with oxygen control system to supply air as per the organic pollution load coming into it. Dissolved Oxygen (DO) or Oxygen Uptake Rate (OUR) based blower control optimizes both energy consumption and process performance. Energy efficient blowers further improve the energy efficiency of the ETP. • Process Automation: Due to variations in wastewater characteristics, it is advisable to install process automation to control vital process parameters such as DO, OUR, MLSS, Sludge recirculation, Sludge wasting, etc. This helps in automatically keeping the process parameters at their optimum levels and generates consistent quality of treated wastewater.

Conclusion Refinery wastewater characterisation is very complex exercise that requires an understanding about the refining processes involved. The designing of the ETP is a challenging job as treatment units have to be robust enough to handle continuous variations in the concentration of pollutants.

The operation of the biological system governs the performance of the ETP, as it removes the bulk of the pollutants.

Ideal operating conditions have to be provided for the microorganisms in order to ensure effective treatment. The biological system should be selected to handle any variations in flow and characteristics of refinery wastewater.

Minimal Liquid Discharge: Adopting A ‘Less Is More’ Mindset Minimal Liquid Discharge (MLD) is a cost effective water management approach that helps increase recovery and also mitigates discharge. If zero liquid discharge (ZLD) is too costly and the associated infrastructure is a latent deterrent, water reuse and sustainability can still be prioritized and realized through MLD. It can assist municipal and industrial plants to make substantial gains in minimizing liquid discharge and help plants considerably abate their capital and operating costs, since achieving the final 3-5 per cent of liquid elimination to accomplish ZLD can prove contemptibly expensive. The article deliberates in-depth on benefits of adopting MLD approach over ZLD approach. It also explains its role in reducing CAPEX, OPEX and other environmental impacts.

Industry challenge Due to urbanisation and industrialisation, India faces major challenges in the water sector with the per capita availability going down and demand going up.

Inefficiency of water use in agriculture, over-exploitation of underground water and contamination are other issues associated with water management in India. Since the amount of water available is more or less constant, rising demands due to increasing population and economic growth are straining the demand-supply balance.

Also with environmental norms becoming increasingly stringent and water becoming a “scarce commodity”, treating water to make it reusable has become an imperative for water intensive industries across the globe.

As we are heading towards developing a circular economy, where raw materials are recycled and reused, many industries realise that the wastewater they generate could well be their cheapest & most reliable source of water and MLD technology can lead the way in that direction.

Why MLD? Maximizing the efficient use of water by industry is critical for both the environment and the bottom line. Depending on individual regulatory and environmental needs and requirements, as well as the capital and operating budget, MLD can be a good fit for many industrial and municipal sites. By conducting a water audit to match waste streams and appropriate water requirements, companies can better 44 • September 2018

identify how much wastewater requires processing and the approach that will most economically and sustainably match their plant’s needs. MLD can help municipal and industrial plants make substantial gains in minimizing liquid discharge and help plants significantly minimize their capital and operating costs, since achieving the final 3 to 5 per cent of liquid elimination to achieve ZLD can prove outrageously costly. (See graphic below.)

Benefits of MLD over ZLD While zero liquid discharge (ZLD) — a water treatment process in which all wastewater produced is purified and recycled, leaving zero liquid discharge at the end of the treatment cycle — is a viable solution for some companies;

it’s not the most realistic solution for all.

Due to the additional material, energy and disposal resources they typically require, it is technically daunting, highly expensive and not necessarily environmentally friendly. Hence when facing significant discharge mitigation costs, businesses often wonder, “What are my other options besides ZLD?” One solution is minimal liquid discharge (MLD), a more cost-effective and sustainable way for companies to improve their water footprint, enabling up to 95 percent liquid discharge recovery at a fraction of ZLD’s costs. Coined by Dow, the processes on which it is based rely on proven water filtration technologies such as ultrafiltration, reverse osmosis (RO), and nanofiltration.

Cost Comparison Of Minimal Liquid Discharge (MLD) VS Zero Liquid Discharge (ZLD)

Chemical Engineering World

Features CEW New MLD-related technologies are enhancing these efforts. For e.g., for municipal desalination plants, it’s possible to get to 93 per cent recovery using a traditional dual-membrane treatment system, chemical adjustments and precipitation. It’s typically a combination of brackish water reverse osmosis, nanofiltration and seawater reverse osmosis. To dispose the remaining concentrate, for many desalination plants, the preferred method of concentrate disposal is discharge into the ocean and if that is not an option, alternatives vary by geography.

Minimal Liquid Discharge

An excellent example of an MLD mind-set in action can be found at the General Motors (GM) vehicle assembly plant in San Luis Potosi, Mexico. The plant, which employs up to 1,800 and has an annual capacity of 160,000 cars, is located in an arid, remote area with no receiving stream or municipal sewer available to discharge wastewater. Yet by using a combination of RO technology, a proprietary high-rate chemical softening process, the plant can convert up to 90 per cent of its tertiary wastewater into reusable water, leaving less than 10 percent of liquid waste for discharge into adjacent solar ponds for evaporation. MLD provides users with a spectrum of options to achieve the results most optimal for a particular plant, based on a variety of factors. For some, it could be 90 percent, for others, it could be 80 or even 70 per cent.

Diversity of Dischargers – MLD Solutions The diversity of types of discharge Chemical Engineering World

streams across industries, markets and municipalities calls for MLD solutions tailored to individual needs. Potential discharge sources and opportunities for MLD-driven improvement include

In the United States, which primarily has small-scale desalination plants, the primary locales for concentrate disposal are evaporation ponds and injection wells. But in much of Asia, given its population densities and environmental factors, surface- or injection-based concentrate disposal are not viable options. In such instances, a reverse osmosis system is typically used to pre-concentrate the brine. Newer technology enhancements for this process include disk tube reverse osmosis, in which an open-channel structure RO system is fed by a turbulent feed water flow system.

Through this process, the system can avoid settling of suspended solids carried in the feed water inside the membrane module.

Cooling tower blowdown – in heavy industry and power plants Ion exchange regenerative streams – particularly in food and beverage processing Flue gas desulfurization – wet wastewater stream Municipal potable water systems – wastewater streams Process water reuse – from agricultural, industrial and municipal streams

Another newer technology variant is the use of forward osmosis, which uses a water permeable, salt-rejecting membrane to separate water from dissolved solutes.

The driving force for this separation is an osmotic pressure gradient, so that a “draw” solution of high concentration (relative to that of the process feed solution) is used to induce a net flow of water through the membrane and into the draw solution.

This process helps eliminate the need and use of high-pressure pumps and can thus potentially operate using a lower energy footprint than evaporative technologies.

In general, all of these discharge sources can be broken into two main themes: volume streams and complexity streams. A tailored approach for MLD will depend on whether it’s tackling a volume stream, a complex stream, or some kind of combination, as well as the geography.

Reduced CAPEX, OPEX and Environmental Impact The cost of membrane-based pretreatment and filtration technologies applied in MLD is relatively minimal compared with the exponentially greater capital and operating costs of ZLD-related September 2018 • 45

CEW Features evaporators and crystallizers. That’s why the advent of new technologies, such as disc-tube reverse osmosis and forward osmosis, is so important to users. They not only extend recovery but can also minimize or even eliminate the size or need for evaporators and crystallizers.

Waste heat can be used from some of these operations to provide additional benefit to an MLD approach.

Evaluating MLD Needs So what is the best way to determine if your plant is a candidate for MLD? Often, the first step is to conduct a water audit to identify the sources and types of wastewater generated in a facility, especially in terms of flow and total dissolved solids content. By matching waste streams and appropriate water requirements, you can better identify how much wastewater (if any) requires processing and the approach that will most economically and sustainably match your plant’s needs. For e.g., some

wastewater sources, such as condensate and storm water require minimal cleaning while those with high concentrations of organic compounds, salts, metals and suspended solids, will likely require more rigorous treatment. Similarly, cooling water and process water do not need to be treated to the same standards as potable water. The most important factor is that an MLD approach enables your plant to address the substantial ‘limbo’ that exists between minimizing discharge, and go-for-broke ZLD. Real-Life MLD Approach Benefits: India Due to considerable effluent discharge by the textile mills of Tiruppur, Tamil Nadu, the Madras High Court, in February 2011, decreed that all dyeing units in Tiruppur would have to shut down for violating pollution norms and would only be reopened when they implemented zerodischarge protocols in order to protect the surrounding farmlands and rivers. In their effort to comply with regulation, minimize

environmental impact while reducing operating costs, the mill owners partnered with Dow Water & Process Solutions (DW&PS). As a result of this engagement, the research team in DW&PS developed a new product line called FORTILIFE™, which is designed to handle the most challenging water applications such as waste water reuse and MLD and give these applications the reliability and efficiency they badly need. With success of the existing pilots, the FORTILIFE™ products are now well on their way to be rapidly adopted by the industry.

Stricter monitoring requirements for combustion emissions

T

he new monitoring requirements being imposed on Medium Combustion Plants (MCPs) and Large Combustion Plants (LCPs) in Europe is symptomatic of environmental initiatives affecting a wide variety of industries. In the following article, Dr Andrew Dixon from Gasmet Technologies UK (formerly Quantitech) explains how instrumentation manufacturers are responding to these new challenges.

The combustion of fuel and waste produces a wide variety of pollutants and greenhouse gases, so regulators around the world are increasingly imposing stricter emissions limits and monitoring requirements as part of initiatives to improve air quality and fight climate change. Generally, emission limit values are being lowered, the number of parameters being monitored is increasing, and the requirement for continuous monitoring is growing.

The growing number of parameters that have to be monitored means that operators have to employ multi-parameter technologies such as FTIR, or purchase a number of analysers to meet the requirements. For this reason, Gasmet UK has developed an integrated systems capability, so that it is now able to design and build complete MCERTS approved monitoring systems, designed to meet plants’ individual requirements.

However, one of the pollutants of major concern, mercury, necessitates a specific monitoring technology, and since the emissions limits are so low, it is necessary for this technology to have performance certification at these levels.

In Europe, member states have the opportunity to set specific limits and monitoring requirements that fit within the framework established by the Industrial Emissions Directive (IED). So, individual states may set stricter limits, or individual plants may implement more rigorous monitoring and abatement technology in order to demonstrate good environmental performance. In most cases, this is undertaken: as part of a corporate responsibility strategy; in response to demands from stakeholders, or in anticipation of tighter future regulatory requirements.

Chemical Engineering World

Mercury is considered by the World Health Organisation to be one of the top ten chemicals of major public health concern, so there are global initiatives to lower the emissions of this toxic element in its various compounds – particularly from power plants, waste combustion and cement plants.

In November 2015 the European Parliament signed a new directive that imposes emission limits on MCPs. Under the directive, an MCP is any equipment that burns fuel, with very few exceptions, and where the rated thermal input is between 1 and 50 MW. Diesel or gas engine generators rated above 400 kVA are also applicable, in addition to any appliance that uses fuel to generate heat or electricity. Boilers, generators and other mobile plants rated above 1 MW thermal input are also included.

By regulating emissions to air of SO2, NOx and dust, the MCP directive aims to reduce air pollution and lower risks to human health and the environment. It has been estimated that the MCP directive will apply to over 30,000 plants in England and Wales. The controls will apply to GasmetCMM Continuous Mercury Monitor new plants from December 2018, and to a combustion plant. This includes the existing plants from 2024 or 2029. gasification of coal and other fuels, and the waste co-incineration plants for nonNew environmental standards for LCPs hazardous waste (>3 tonnes/hour) or for strengthen the requirements of the IED for hazardous waste (10 tonnes/day). both reduction and monitoring requirements.

This includes new BAT- MWth, when coal and/or lignite is used, associated emission levels (BAT-AELs) including waste co-incineration; and for and sets new monitoring requirements for hydrogen chloride when solid biomass sulphur dioxide, nitrogen oxides, mercury, and/or peat is used in LCPs or waste coand particulate matter. The BAT conclusion incineration plants. was published in August 2017, and will come The BAT-AELs for mercury emissions to air into effect with a four year transition period. from coal and lignite burning power plants The LCP BREF applies to combustion plants are extremely low. For example, a new th with a total rated thermal input exceeding coal-fired power plant with ≥ 300 MW has 3 50 MW. However, it also applies to smaller a BAT-AEL of <1-2 μg/Nm mercury (yearly units where they are directly related to average), and an existing lignite-fired power September 2018 • 47

CEW News Features station with a thermal input under 300 MW has a BAT-AEL of <1-10 μg/Nm3 mercury.

It is interesting to note that the draft waste incineration BREF (WI BREF) also requires continuous mercury monitoring and currently stipulates a daily average of 5-20 μg/Nm3 mercury emissions to air for new plants and 5-25 μg/Nm3 for existing plants. In the BREF guidance for cement kilns (CLM BREF), mercury has a BAT-associated emission level of 50 µg/ Nm3 for the half-hour average.

However, in countries such as Germany, stricter emission limits have been adopted.

In some circumstances continuous mercury monitoring will be specified in the regulations, but in others, non-continuous methods may be allowed. This latter option may have a lower purchase cost, but it merely provides an average of a plant’s emissions over a certain time and therefore may not be considered the most effective way to protect the environment, because continuous monitoring provides a complete

picture of a plant’s emissions. This helps to identify the source of pollution peaks, and to inform mitigation and abatement strategy. In addition, as emissions monitoring and control regulations become more stringent, continuous monitoring may become obligatory at a later date, for some types of plant.

Monitoring equipment must be MCERTS certified to perform within the requirements of a permit, which is why the possibility of continuous monitoring should be considered, and both current and future requirements for certified monitoring ranges and levels of uncertainty should be addressed. For these reasons, the recent certification of Gasmet’s Continuous Mercury Monitor (CMM) is of particular significance. The Gasmet CMM has successfully completed EN15267-3 testing using CVAF (Cold Vapour Atomic Fluorescence). Importantly, this instrument now provides the world’s lowest EN15267 certified range for measurements of Mercury.

The CMM is certified for operation across a

number of different ranges up to 1000 µg/ m3, but considering the latest regulatory requirements, the CMM’s certified range of 0 to 5 µg/m3 will be of particular relevance to the operators of combustion processes.

In summary, when defining a monitoring strategy it is vitally important to take future requirements into account (from both regulators and stakeholders) when choosing appropriately certified technology.

In addition, for new plants, monitoring requirements should be assimilated into the plant design at an early stage. Expert advice should be sought to ensure that the right equipment is specified in order to optimise the installation, ensure compliance and future-proof monitoring activities.

Can India replicate Middle East’s Desalination Success Story

W

ater is an essential ingredient in across industries, not just in the products but also in the preparation for cleaning the products, processing and other uses. While 71% of the earth’s surface is covered with water, only a tiny amount (0.6%) is fit for consumption.

The supply of clean and fresh water is fast decreasing. In contrast, the demand for consumption of water is fast increasing due to a growing global population, agricultural activities and economic development. Pressures from both, the supply and demand sides means that clean water is increasingly becoming hard to source. While the future outlook for India’s capability to meet the growing demand seems to be grim, India can perhaps turn to their neighbours in the middle east to replicate their desalination model.

In the last two decades, desalination plants have evolved rapidly to extract fresh water from the sea. At present, nearly 150 countries 48 • September 2018

rely on desalination plants to meet their fresh water requirements. The Middle East and North Africa (MENA) region accounts for nearly half the world’s desalination capacity, according to World Bank calculations, making it the largest desalination market in the world. According to Global Water Intelligence, the world’s desalination market is projected to reach $7 billion by 2022, with the Middle East and North Africa region to account for $4.3 billion.

Middle East’s desalination success story Typically, in the desalination process, the source water (either sea or polluted water) is distilled using either thermal or electrical energy. This process removes salts (fluorides, chlorides, sulphates, etc.) which are found dissolved in water, thereby rendering the source water fit for consumption (called distillate).

However, this process has one major drawback — it consumes a large amount of energy, which is traditionally derived from

fossil fuels. Considering the fact that India is steering itself towards fossil-free energy generation, it would be practical to combine the shift towards renewable energy with desalination technique.

Set up over a decade ago by the Arabian Construction Company, the Shuweihat S1 Independent Power and Desalination Plant in Abu Dhabi, UAE, is currently one of the world’s largest combined power and water plant complexes, delivering 1500 MW of power to the emirate of Abu Dhabi. The plant is linked to a seawater desalination facility which is supplied with steam from the turbines.

Similarly, in Oman, the desalination market in the country has been expanding by a little over 5 percent per year thanks to rapid urbanization and population growth.

South Korea’s Doosan Heavy Industries & Construction Co. will take part in a $203.9 million desalination project in Oman, the latest in its series as the world’s biggest Chemical Engineering World

News Features CEW desalination plant builder. The new desalination plant will be built in Sharqiyah region, 220 kilometers South East of Oman’s capital, Muscat. The plant will be designed to use reverse osmosis method and will be able to supply 80,000 tonns of fresh water, enough to meet the water demand of 200,000 people a day.

Why desalination is relevant in India Potable water is scarce in India and has become one of the major challenges for the country today. According to a recent report by the National Institution for Transforming India, a policy think tank, about 200,000 Indians die each year due to inadequate access to potable water, with 600 million facing what is termed ‘extreme water stress.’

Furthermore, studies suggests that by 2030, the water demand in India will double. This would result in severe water shortages for millions of people.

India holds just 4 percent of the global freshwater, despite having nearly 16 percent of the world’s total population. The ability to use seawater that most coastal states have access to is perhaps the most prudent solution.

Combining renewable energy based technologies to power desalination plants will ensure that the production of pure water is non-polluting. The benefit of this scheme would be two-fold. Firstly, clean drinking water would be produced to alleviate water stress. Secondly, the use of renewable energy based plants will help abate the effects of climate change.

Current industry overview and steps taken by the Government of India The most popular desalination technologies include Multi Effect Distillation (MED), Multi Stage Flash (MSF) and Reverse Osmosis.

MED and MSF techniques are heat based while reverse osmosis is a pressure based technology using a membrane, similar to a filter paper, to separate salts from the raw water. Over 70% of the thermal desalination plants have already shifted over to reverse osmosis technology globally. While looking forward, Adsorption Desalination (AD) is being researched and developed as one of the most energy efficient processes. These can be powered by multiple renewable energy based power systems.

The final combination of desalination technologies and their renewable energy Chemical Engineering World

based power systems depends on factors such as source water availability, environmental constraints, location, distillation capacity and cost of desalination.

However, cost and capacity are usually the key considerations.

The government is already working on implementing a desalination policy.

At present, India has three operating desalination plants on the Lakshadweep islands. The country’s topmost think-tank NITI Aayog has been planning similar plants across the country. Proposals for desalination plants at Tuticorin, Paradip and Kandla are also already under consideration.

However, not everyone is in favour of desalination. Effluent waste management from desalination plants including brine concentrate and other effluents pose huge concerns globally. Despite advancements made towards ‘zero liquid discharge’ technologies, where the brine concentrate is converted into solids fit to be disposed at landfills, the costs at present remain steep and must be taken into consideration to avoid any serious ecological complications which have occurred in the past due to poor planning.

Call to action Ensuring access to safe water for the masses is the need of the hour. This essential resource is both limited and steps for course correction are still at a nascent stage. Freshwater sources are drying up quicker than the rate at which they are being replenished. Getting the desalination policy right would definitely be a shot in the arm for India’s long-term strategy to mitigate water stress and solve the country’s water problems.

Energy Efficient Compressors for Cost Reduction Conrad Latham, General Manager, Compressor Technique, Atlas Copco (India) Ltd shares insights into the company’s growth strategy in India and innovations for improving overall efficiencies and cost reductions for customers.

T

he growth strategy for Atlas Copco compressors in India is to provide our customers with the most suitable solution depending on their needs.

Customers are foremost focused on a compressed air system that is reliable. In order to produce their products they need compressed air. Atlas Copco compressors provide this reliability as standard and over the years manufacturing has demanded more in terms of energy efficiency. This is the driving business strategy for Atlas Copco and it is what shapes the decisions for product and service developments. “In today’s India market the key to success is understanding the needs of the customer and then being able to adapt your offering to meet this need. For this close interaction with the customer is required and this remains our focus as we develop our sales and service channels,” says Latham.

Talking about the growth growth strategy f o r A t l a s C o p c o ’s A i r C o m p r e s s o r business, Latham expresses that the company is replicating the global model for the customers in the Indian market.

Competitiveness of customers is often driven by the ability to reduce costs and increase productivity. He observes that specifically the energy cost for compressed air forms a large portion of the energy bills for their customers. Knowing that, the constant push to reduce energy costs through developing innovative solutions drives the global products and solutions.

Even a small percentage if reduction in energy costs can result in significant reduction in energy costs for the customers.

Market size data is difficult to assess both globally and for India as there is no single, independent reporting process. However,

50 • September 2018

the best estimates that Atlas Copco has for the global size of screw air compressors is somewhere between 200,000 – 250,000. For India, Latham says that it is estimated at approximately 10 per cent of global market.

The competition in the Indian market can be clearly divided between the organized and the unorganized compressor suppliers. The organized competitors are those companies that have a diverse product portfolio and a structured sales channel of direct sales and indirect sales (dealers). They are constantly developing their products and some are even having multiple service solutions like Atlas Copco. The organized players are well dispersed with sales and service people across India. The unorganized players are companies that are either importing compression elements and then mounting locally a drive system and selling in a local area. Often such companies struggle to develop the product and to provide service beyond the local region.

“For us, India is an extremely exciting market due to the present and expected growth in manufacturing. The focus to make manufacturing a larger portion of the GDP and the Make In India initiative is beginning to see companies investing,” states Latham.

He shares that compressor technology under goes regular innovation and the drive to reduce the energy bills of our customers is the main force behind a lot of the innovation.

Some of the big changes are the move from fixed speed compressors to variable speed compressors, that use only as much energy as required from the varying demand of the customers application. Recent changes have seen new designs in the compression process of the oil-free screw

compressors. Atlas Copco has invested a lot of money in Computational Fluid Dynamics calculations to truly understand the detailed flow patterns of air as it moves through a compressor and has used it years of experience, test data and production statistics to highly refine the air and cooling medium channels in a compressor to drastically reduce pressure drops thereby improving the energy efficiency of the compressors it develops.

A lot of innovation is taking place with Industry 4.0 and Atlas Copco has developed its Smartlink system, where it connects the compressors and dryers to a centralized data warehouse. From here it can provide a huge amount of running data to improve uptime reliability for its customers as well as energy optimization solutions. The latest central compressed air room controller, Optimizer 4.0, is a great development in innovation, again driven by the desire to reduce customers energy usage. This unique controller can centrally optimize multiple compressors and dryers of different technologies as well as different compressor manufacturers.

It is not only in compressors and software t h a t d eve l o p m e n t s a r e t a k i n g p l a c e.

Compressed air dryers are also a great area of energy saving and recently Atlas Copco launched the world’s first rotary drum dryer that guarantees -40 o Celsius pressure dewpoint. This is a compressed air dryer that uses almost no electricity to provide compressed air at a very high quality. Normally such systems would cost customers more than ` 11lakhs in electricity per year, and now we can provide a solution that is almost free to operate, which is real innovation.

DECEMBER 2017

In the last year Atlas Copco has seen a very positive trend in the growth of products sold to the Chemical Industry in India. There are a couple of reason for this growth. First is investment is coming to update existing production facilities to be more productive.

We have seen investment in not only the compressor and blower equipment but also in the updating of the compressed air pipe network to reduce leakages and pressure drops which saves a lot of in running costs.

The second is in the development of new plants. Here companies are expanding to cater for the growing demand and are choosing energy efficient solutions.

Recently Atlas Copco launched a series of new products from its Oil-free Air Division.

These included it’s next generation of screw blowers which are able to deliver energy savings up to 35 per cent for applications like fermentation and waste water treatment.

Also, the new oil-injected screw compressor which as well as bringing market leading energy efficiency also reduces the service time by 50 per cent. This provides customers with a higher uptime. The latest extension of the oil-free turbo ZH range was also launched and now the standard centrifugal compressor is available up to 3.1 MW. This is a great product for the chemical industry where more and more standardization is being seen globally. Drive for efficiency and lower delivery times are the main focus for customers. A new heat of compression rotary drum dryer that can guarantee a pressure dewpoint of -40 o C elsiushas been launched as well. This is a unique product in the market and no other company has the capability to do this. It means that the normally high energy costs of twin tower desiccant dryers can be almost eradicated.

To top the new products, we have also launched an extremely innovative oil-free screw compressor which will cut energy costs by 10 per cent. The new ZR90160+ VSD range is using all the years of proven experience we have in oil-free screw technology and combining it with cutting edge technology to further improve reliability and energy efficiency.

CHEMICAL ENGINEERING WORLD

Indian market is highly price sensitive as compared to other global markets, which all the international players are very much aware of. They understand that to be competitive in India, they need to provide products that represent their brand promise of quality and reliability at prices acceptable in the market. There are companies that are willing to pay for the value of options that are normally associated with improved energy efficiency like variable speed drive compressors, permanent magnetic motors, cost-effective adsorption dryers or even higher IE rated motors.

The process combines the chemical principles of absorption and adsorption.

In the system, micro-organisms settle on the surface of an organic carrier material.

Their metabolic processes are used to convert the polluted emissions into carbon dioxide and water.

To that end, the polluted gas is blown through the bio-media from the bottom of the system. In the roof of the system, automatically controlled nozzles are installed, spraying water with nutrients and minerals into the trickling layers, on which micro-organisms are located. The nutrient liquid ensures the optimal metabolic conditions for the micro-organisms used. And the automatic recirculation of the nutrient liquid ensures a very high-efficiency by removing polluted air with very low operating expenditure.

ECOFLUX* Corrugated Tube Heat Exchanger

H

RS Process Systems Ltd, India, is part of UK-based HRS group of companies, a leading heat transfer technology provider. HRS is equipped with a strong network all across domestic and international market like UK, Spain, USA, India, Australia, New Zealand and Malaysia to fulfil technology needs of process industries.

The high demand for heat transfer equipments in industries like chemical, pharmaceutical, agrochemical, petrochemical, oil and fats, fertilizer, food and beverages, engineering and others is driving the advancement in heat transfer technology. Heating, cooling, chilling, condensing, re-boiling, pasteurizing, sterilizing, evaporating are the key processes in these industries. To carry out such processes effectively, heat exchanger becomes heart of the process plant.

During heat transfer process, over a period of time, deposition of substance occurs. Formation of this boundary layer

is referred to as FOULING, a factor which poses resistance to product flow. Fouling is typically high in shell and tube (smooth tube) heat exchangers and significantly impacts the heat transfer process.

HRS offers ECOFLUX corrugated tube heat exchanger (CTHE), which is a shell and tube heat exchanger where “corrugated tubes” are used instead of plain tubes. This is a definitive option to tackle fouling seen in regular shell and tube heat exchangers. The tubes in ECOFLUX CTHE are corrugated to induce turbulence in both the flows

(product and service) even at lower velocity.

Corrugated tube thus, boosts heat transfer multi-fold even at low Reynold’s number with minimum increase in pressure loss.

This enables efficient heat transfer even in liquids with high viscosity, large fibers or particulates.

ECOFLUX corrugated tube heat exchangers are compact in yet give significantly enhanced performance over smooth tube heat exchanger. It can be customized according to the process needs with wide choice of MOC like SS-304L, SS-316L, 904L, 321, Titanium, Duplex, Hastellloy, Alloy 20 and Copper depending upon compatibility of process fluids.

ECOFLUX CTHE is offered in a range of models as per ISO, TEMA and latest design standards to suit different process applications. It enables continuous process running for longer duration, requires low maintenance and also gives high response to CIP. This proves to be a versatile, economical and energy-efficient equipment for multiple process industries.

Automation of Centrifuges The API production and schedule M drugs limitations require time-based production with necessary process steps. The dependence of production on human-beings may spoil the quality of production.

ACE has thoroughly studied all the process steps of bottom discharge centrifuge. The total control of the machine is done electronically.

Use of variable frequency drive (VFD) coupled with PLC has opened the gateway of automation.

Their FLP control system has been incorporated with HMI/MMI. The user can easily get the following time-based benefits with their flameproof control panel: batchwise recordings of individual steps with respect to date/time/batch numbers are stored in the system and the printout is available as and when required. The total cyclic operation can be different for different products. The control of the equipment can be managed from a particular desktop computer. The use of VFD in centrifuges is a great advancement. The VFD of a standard make is used preferably one that has an in-built braking chopper and resistor. The centrifuge runs with high starting and braking torque. Although ACE clutch pulleys and hand brakes are sturdy enough to do the job, the VFD does it electronically. The wear and tear of brake and clutch liners is negligible. It is worthwhile to invest in a VFD. The variable speed is welcome to save power. The VFD gives smooth centrifuging operation. Also, the work of feeding and washing can be done at lower basket speeds and the centrifuge drying can be done at higher speeds, if the basket charge is properly balanced.

Pump Impeller The KSB Group offers a special impeller for its Movitec multi-stage high-pressure pumps. This new impeller significantly improves these pumps’ suction characteristics (NPSH value).

It proves its worth particularly in applications with critical inlet conditions (eg, boiler-feed applications) as well as applications in which the pump is required to take in water from low-lying tanks or at higher temperatures. Under these conditions, a pressure drop in the intake area may cause cavitation to occur in the first pump stage. This can result in excessive wear of pump parts or motor bearings as well as a reduced service life of the pump due to damaged parts and an unbalanced hydraulic system.

The new impeller features a modified inlet dia, vanes allowing a slightly diagonal throughflow and a newly designed stage casing, all of which serve to substantially improve the pump’s NPSH curve.

The multi-stage centrifugal pumps from the Movitec range are designed for handling fluids such as water, coolants, condensate and mineral oils. They are ideal for a wide variety of applications ranging from industrial boiler feed installations in steam circuits, recirculation and fire-fighting systems, cooling water circuits and washing plants to pressure boosting in general process applications.

Condition Monitoring & Predictive Maintenance NORD DRIVESYSTEMS uses condition monitoring and predictive maintenance to achieve max plant availability and high cost-efficiency. While condition monitoring only enables the state of wear to be detected, predictive maintenance can ideally enable a maintenance date to be planned well in advance.

This requires intelligent frequency inverters with integrated PLCs, which can take autonomous decisions and evaluate motor and gear unit status data from virtual and physical sensors. With the aid of virtual sensors based on mathematical algorithms and the PLC which is integrated into the NORD frequency inverter, in combination with the known physical characteristics of the gear oil, the lifespan of the oil can be determined with sufficient accuracy from the calculated drive output which is determined from the measured electrical data. This allows an assessment of the degree of use of the gear oil and the predicted date for the oil change.

For industrial gear units, physical temperature and vibration sensors are both economical and advisable. Especially vibration sensors offer a range of advantages. Detailed manufacturers’ databases exist for all of the bearings which are installed in industrial gear units. These databases contain the characteristic vibration frequencies for all components of each bearing type. The individual frequencies can therefore be clearly identified and attributed to particular components. The frequency spectrum can be analysed on the basis of the time signal or an FFT analysis (Fast FourierTransform). This not only enables the ideal or necessary maintenance time to be calculated, it also indicates the location of the fault and which replacement parts are required. The autonomous drive communicates its status data to a secure cloud. There, this data is available for analysis with filter and analysis tools, so that monitoring of the drive units can be carried out from anywhere in the world. The data are transparently presented in a browser-based web interface and the plant can be viewed at a glance in a clear 3D illustration.

CEW Products 8-Axis FaroArm FARO offers 8-Axis FaroArm system. This comprehensive, solution combines either the portable Quantum FaroArm, Quantum ScanArm or Design ScanArm portfolio products with a functionally integrated, yet physically separate, 8th axis.

The 8th axis is a complete rotational axis identical to and a natural extension of all FaroArm products. It plugs directly into the FaroArm and results in a seamlessly integrated, high accuracy additional axis that requires no additional setup time or effort. Moreover, unlike a turntable, the 8th axis is completely transparent to the measurement software, so no software updates or upgrades are needed.

This innovative functionality enables the part to be rotated in real time relative to the Arm versus requiring the Arm to be moved around the part. As a result, it is not only easier to scan and measure typically harder to reach areas, but also both measurement time and human measurement error are dramatically reduced since the part itself rests on a stable, consistent platform.

The 8-Axis system is ideal for addressing a range of non-contact measurement and design challenges, including point cloud comparison with CAD, rapid prototyping, reverse engineering, and 3D modelling of free-form surfaces.

Drive Solutions To optimise the total cost of ownership (TCO) NORD DRIVESYSTEMS offers individual TCO calculations, integrated concepts for costs and efficiency optimisation as well as powerful and efficient drive technology.

The total costs which a product generates over the course of its life cycle can be calculated with the aid of a TCO calculation. To optimise the TCO, NORD supplies efficient drive solutions which considerably reduce operating costs. Here, the focus is on an integrated approach. This includes reduction of the number of versions with the aid of the NORD modular system, reduction of energy consumption through the use of efficient IE4 synchronous motors; long service life and low maintenance NORD drive units.

Drive systems count as the main consumers of energy in industry. Energy saving IE4 synchronous motors from NORD are highly efficient, thanks to PMSM technology, also in the partial load and speed ranges.

The second largest factor for reducing costs is the deliberate reduction of the number of versions. This minimises administrative expenses, and enables leaner manufacturing, logistics, storage and service processes. The necessary basic versions which are required in order to reduce the total number of versions can be selected from the extensive NORD modular system. In addition, NORD systems facilitate reduction of the number of versions and spare parts management.

Project Update CEW New Contracts/Expansions/Revamps The following list is a brief insight into the latest new projects by various companies in India.

CHEMICALS Songwon Industrial Co Ltd a specialty chemicals company of South Korea has launched its new pilot plant in Panoli (Gujarat), thereby strengthening the organisation’s overall specialty chemicals development capability. Built on Songwon’s Indian site with all the necessary main unit operations, the new plant is equipped with the most up-to-date technologies and materials for producing a wide range of chemicals for a broad spectrum of applications - from one kilo up to several hundred kilo samples. To reinforce the organisation’s position in existing areas of business and enhance its ability to enter new areas, the new pilot plant will be supported by the Songwon’s strong local R&D team in Panoli, as well as its central technology innovation center located in Maeam, Korea.

valuation of the prospective deal is not known. JSW Energy refused a comment on the status of its takeover plans of Monnet Power and JITPL. NLC India (formerly Neyveli Lignite Corporation) which is in the hunt for buying out power assets, is understood to have shown interest in the 700-MW Odisha plant of Hyderabad-based Ind-Barath Power Infra Ltd (IBPIL). The power plant located at Sahajbahal, near Jharsuguda, has commenced commercial operations. Though the exact size of the potential deal is not known, the valuation could be anywhere in the range of ` 5,000-5,500-crore. In August last year, NLC India had floated an Expression of Interest (EoI) from companies owning coal and lignite-based power projects, for a possible acquisition. NLC India’s installed thermal power capacity is 3,240-MW. It runs a 10-MW solar power unit and wind power assets with a capacity totalling 37.5-MW.

MINING KIOCL will revive mining in Karnataka, after the State granted the company a lease of over 474 hectares at Devadaru hills in Ballari.

KIOCL had suspended mining in the eco-sensitive Western Ghats following a Supreme Court directive in 2006. Once approvals are given, it would invest ` 1,500-crore in a pellet plant and also a unit to enrich iron ore from the mines. After suspension of mining, KIOCL had shifted to operating 3.5-million tonne per annum pellet plant in Mangaluru. Last year, it produced 1.46-million tonnes, utilising half its capacity, as against almost nil production in the previous year. International agencies have already implemented pilot projects by bringing high grade iron ore from South America, Iran and other parts of the world and utilising KIOCL's facility, have taken away pellets facilitating better utilisation of its plant capacity and profitability utilising its manpower. The company's blast furnace unit having a capacity of 216,000-tonnes of pig iron which was put under suspension since 2009 has been taken for repair and the unit is ready for operation for producing foundry grade pig iron adding towards its profitability in the coming financial year. The firm earned a profit of ` 47.93 crore in FY17 as against a loss of ` 80.15-crore the previous year.

Revenues grew 353 per cent to ` 929.36-crore from ` 205.57-crore in the previous fiscal.

Western Coalfields has received the environment clearance for its ` 263-crore expansion project in Nagpur district, Maharashtra. The proposal is to enhance the production capacity of the Gokul open-cast mine to 1.875-million tonnes per annum (MTPA) from the existing 1-MTPA. The mine, located in 767.17-hectare, has a mineable reserve of 14.50-million tonnes. The clearance to the project is subject to certain conditions. Total cost is estimated to be ` 263-crore. Among the conditions specified, the company has been asked to get 'Consent to Operate' certificate from the State Pollution Control Board for the existing production capacity of 1-MTPA and also the 'Consent to Establish' for the proposed capacity of 1.875-MTPA prior to enhancing the production capacity. With regard to transportation of coal, the company has been asked to carry out by covered trucks and take mitigative measures to control dust and other fugitive emissions all along the roads by providing sufficient numbers of water sprinklers. The company has been informed to adopt controlled blasting techniques to control ground vibration and flying rocks. It has also been told to implement a progressive afforestation plan covering an area of 376.04-hectare at the end of mining. Of the total quarry area of 231.73-hectare (on floor) and 291.21-hectare (on surface), the backfilled quarry area of 115.39-hectare should be reclaimed with plantation and there will be no void left at the end of the mining operations. The land after mining should be restored for agriculture purpose.

JSW Energy, part of the Sajjan Jindal-led JSW Group, is believed to be in the race for buying out the thermal power assets of Monnet Power and Jindal India Thermal Power Ltd (JITPL) in Odisha. Monnet Power’s 1,050-MW coal-based power plant near Angul was in advanced stage of commissioning. Monnet Power’s parent company, Monnet Ispat & Energy had won the Mandakini coal block in Odisha in competitive bidding, it surrendered the block later on grounds of economic unviability. Monnet Power had accumulated debt in excess of ` 5,000-crore. Though lenders had earlier denied a haircut in JSW Energy’s prospective deal to acquire majority equity in Monnet Power, the Sajjan Jindal-owned firm is still believed to be in the hunt for the asset. Besides Monnet Power, JSW Energy is also eyeing takeover of BC Jindal controlled JITPL’s 1,200-MW coal-based plant at Derang near Angul. The first unit (600-MW) of the 1,200-MW plant had begun commercial operations and started power supplies to the Odisha grid. But, coal paucity and absence of firm linkages had caused disruptions in the operations of the power plant. This project has been completed at a cost of ` 7,537-crore which includes a debt component of ` 5,900-crore. JITPL has power purchase agreements (PPAs) with Odisha’s Gridco Ltd, Kerala State Electricity Board and Tata Power Trading Corporation. Apart from JSW Energy, JITPL also had competing offers from Adani Power and Singapore’s SembCorp. The Chemical Engineering World

The company has 500,000 litres by far the largest in Asia to manufacture colour dispersions and is scouting for 10 to 12 acres of land parcel for capacity addition.

“Adding life to colour,” a tagline that aptly describes the unique brand value Soujanya Group as a dominant colour dispersion manufacturer demonstrates for more than three decades holding the mantle of family-owned business strong and reigning a supreme competitive edge in the industry. The group is now evolving further to emerge as a tech player in the colour space. The group was founded by paint technologist, C G Bhumkar in 1982 as Soujanya Enterprises, a proprietorship 72 • September 2018

unit in Navi Mumbai. The first batch of aqueous paste was produced and released only in 1983. Since then, the company has been growing from strength to strength with an optimistic outlook for the future.

“During the last decade, we have grown significantly in terms of size, scale, markets and number of customers. Today, we are amongst the top three colour dispersion manufacturers globally, and

the largest in Asia. Our products are not just sold in India but also globally across 30 countries. We hone repute amongst our customers as a ‘reliable partner for colour’,” says Bhumkar.

Interview CEW for business and has about 20 qualified professionals in her R&D team. “R&D is always integrated into marketing, so they go hand-in-hand at Soujanya. The marketing team works very closely with the technology department to develop customised solutions and, together they form a team to do business acquisition.

Our technology department is a marketfacing department which is directly exposed to the markets.” The unified team at Soujanya Group works towards understanding customers and how they can help them do business better. “We adhere and abide by the international best practices and standards – be it in product manufacturing, communication, team and people, quality, technology, approach to customers, markets or marketing strategy. 30 per cent of the company’s sales is from export markets. We do not see ourselves as a product seller but as a solution provider,” Bhumkar asserts.

For over thirty years, Soujanya has been at the forefront of innovation in colourant manufacturing and research. The company has state-of-the-art manufacturing facility in Mumbai built on 3-acres of land. It is a fully-automated high-tech facility with the entire plant being engineered in Switzerland. “Our engineering partner is a Swiss company responsible for designing our current manufacturing plant, the equipment and machinery is from Germany and Switzerland. Inauguration of our firstof-its-kind facility in 2010 created a splash in the industry and set new benchmarks in colour manufacturing,” Bhumkar shares.

The current facility operating at full-capacity is the largest in Asia manufacturing 500,000 litres of colour dispersion. Also, having started satellite manufacturing units in the area, the company is currently on keen lookout for 10 to 12 acres of land parcel to set up another facility within Maharashtra limits, relatively closer to Mumbai. “We have one of the best technologies in colour dispersion on a global scale and can claim ourselves to be the tech leader in the space. We operate on home-grown technology and have no tie-ups with any external parties as technology partners.”

Business Challenges Raw material costs are one major challenge faced by the industry at large.

Dealing with the pressure and situation at hand, she thinks, “We are in an industry dependent on organic chemicals, which is further dependent on the price of crude. I think the world is right now in a state of chaos and in this rapidly changing world, it is important to try to do the best you can under given circumstances. We are trying to be an agile, flexible and adaptable organisation. Considering the trend of inflation and increase in prices, we have to wait and watch to see the change in industry trends. As a company we are extremely committed to markets, growth and to becoming a global corporation of top-notch order.”

Industry Expectations from GoI Bhumkar highlights two clear expectations from the Government of India (GoI), one is the need for clear and simplified policies from the government and further crystal-clear communication of these policies to the industry at large.

The industry should be extremely clear on what is expected of them in terms of performance and delivery. Second better infrastructure provision is expected from the government. Looking at infrastructure such as roads, power, water, hygiene and sanitation facilities, the gaps need to be addressed effectively with right solutions.

If government works towards meeting these expectations and bridging gaps, you will witness rapid accelerated growth of a nation. The company aims to be a strong and dominant player in the colour dispersion space.

norms and it is a zero-discharge facility.

“We have worked with a French-design firm to get the architecture of the manufacturing plant designed right.

The plant is beautifully designed with ventilation, air, and lighting to operate under ambient conditions without the need for extra lights, thus minimising overall power consumption. We work at par with international standards and make no compromises on the same.

The policies designed for products and manufacturing practices is formulated bearing on mind sustainability goals of the organisation.”

Sounjanya Group incorporates peoplefriendly workplace policies and reinforces consistent belief in equality at every level of operations – right from an individual on the shop floor to the directors, helming the group’s overall operational workings.

Bhumkar believes, “Every job is important, and when each person delivers their best is when the company grows. So, there is equality, and everyone is treated equally.

In terms of CSR activities, today we are falling under the purview of the CSR norms as per the Indian Companies Act. We have a rule of making allocations, which is divided into few of the areas wherein we feel the need to make contributions towards the society. From this year onwards, we will not only be donating sums but will also be participating in social causes.”

CSR (Corporate Social Responsibility) in Focus Sounjanya is a silver-rated CSR-certified company by EcoVadis, a globally reputed major that certifies corporations for their CSR contributions. Honing a mindset of sustainability at its core over the years, the manufacturing processes at Sounjanya are leaning towards greener chemistries. Some of the new products slated to launch soon in the market are all green. The manufacturing facility is also built as per the green-building design September 2018 • 73
