CEW Technology News Graphene Sieve Turns Seawater into Drinking Water London, UK: Researchers, including one of Indian-origin, have developed a graphene-based sieve capable of removing salt from seawater, an advance that may provide clean drinking water for millions of people When immersed in water, graphene-oxide membranes become slightly swollen and smaller salts flow through the membrane along with water, but larger ions or molecules are blocked.

Researchers from University of Manchester in the UK have now successfully developed graphene membranes and found a strategy to avoid the swelling of the membrane when exposed to water.

The pore size in the membrane can be precisely controlled which can sieve common salts out of salty water and make it safe to drink, they said. When the common salts are dissolved in water, they always form a 'shell' of water molecules around the salt molecules.

This allows the tiny capillaries of the graphene-oxide membranes to block the salt from flowing along with the water.Water molecules are able to pass through the membrane barrier and flow anomalously fast which is ideal for application of these membranes for desalination, researchers said.

"Realisation of scalable membranes with uniform pore size down to atomic scale is a significant step forward and will open new possibilities for improving the efficiency of desalination technology," said Rahul Nair, professor at University of Manchester.

"The membranes are not only useful for desalination, but the atomic scale tunability of the pore size also opens new opportunity to fabricate membranes with on-demand filtration capable of filtering out ions according to their sizes," said Jijo Abraham of University of Manchester.

To Reduce the Carbon Footprint Institute of Technology Recycles Waste To Generate Electricity Mumbai, India: Indian Institute of Technology (ICT) is taking giant leaps forward to convert its Matunga situated 16 acres campus into a green zone by recycling waste material such as waste water to generating its own electricity.

To reduce the institute’s carbon footprint , the institute is mixing traditional methods with modern methods to recycle waste some of it which the institute itself have developed.

After separating various materials like metal, wood and plastic the institute aims to recycle and use it for constructional purposes. “Nothing is wasted. Everything is reutilised,” said Bhalchandra Bhanage, dean, infrastructure and campus development at ICT .

The institute will also be installing solar panels to generate 750kW of electricity which in order will help the institute in saving ` 15 Lakh annually. Keeping the conservation of water in mind the institute has also installed ‘auto indicators’ on the 20water tanks in the building , the institute uses a borewell to water the plants pon the campus instead of using water given

by Brihanmumbai Muncipal Corporation (BMC).

10 • April 2017

Currently the institute is also planning to install facilities to treat chemical laden ‘grey’ material from laboratories and sewage water to residential areas. the technology to recycle sewage water has been developed in-house by researchers at the institute’s DBT-ICT Centre for Energy Bioscience. Under this technology, various species of algae are used to treat sewage water. The algae treatment plant is expected to treat an estimated 20,000 litres of water daily.

“We started this project in 2009 and have been improvising on it. It is a pilot project and will launch it on a larger scale in the next five to six months,” said Reena Pandit, a research scientist at the centre.

CHEMICAL & PHARMA INDUSTRY

CEW Press Release Pushing the Boundaries of Possibility With Innovative Coating Raw Material Developments Europe: Covestro, formerly Bayer MaterialScience is appearing at the European Coatings Show under its new name for the first time.

The focus is on innovative and sustainable coating raw material developments and their use in near-series projects. More than just examples of concrete applications, they also document the great interest of key industrial segments.

“For 80 years innovations have been the engine of progress for our company,” said Board Member for Innovation and Chief Commercial Officer Dr Markus Steilemann while speaking to journalists. “We don’t rely solely on our own research efforts here, but also collaborate intensively with partners along the value chains. This enables us to push existing boundaries and offer added value for our customers.”

Sustainability targets met “But all of our developments must also meet our sustainability goals,” said Steilemann. “They should drive energy efficiency and improve people’s lives, but also reduce our own use of fossil raw materials.

At the European Coatings Show we are using concrete projects to illustrate how they can also meet the sustainability goals of our customers.”

Covestro therefore wants to bring more bio-based products to the market, provided that they are cost-effective, have a small ecological footprint and their technical properties are at least as good as, if not better than, those of existing petrochemical-based products.

Renewable coating raw materials trending The use of bio-based coating raw materials is becoming increasingly important. One of the driving forces here is growing market interest in sustainable products. Covestro is committed to raw materials from biomass and has now expanded its portfolio once again.

The latest product is the hardener Bayhydur eco 7190. It is the first polyurethane hardener for waterborne, two-component polyurethane coatings and is well-suited for coating furniture more sustainably, for example. The raw material is the perfect complement to the hardener Desmodur eco N 7300 and the dispersion Impranil eco. All three products are made from up to 70 per cent biomass and do not compete with food production.

It contains the coating hardener Desmodur eco N 7300, which helps to improve the customer’s eco-balance without compromising product quality. “The three partners were very pleased with the results obtained when coating the test bodies on existing equipment at Audi,” said Daniel Meyer.

Debut in rail vehicle coating The bio-based hardener also recently made its debut in the coating of commercial vehicles. Polish rail vehicle manufacturer Newag SA used a coating formulated with Desmodur eco N to coat two diesel locomotives. Lankwitzer Lackfabrik of Berlin developed the coating in close collaboration with Covestro. The coating meets the specifications of the rail vehicle industry and offers 70 per cent better gloss stability and abrasion resistance than standard coatings.

Milan-based furniture specialist RiFRA, coatings manufacturer Sirca and Covestro conducted a feasibility study to demonstrate that waterborne furniture coatings could be formulated even more sustainably by reducing the content of fossil resources. They succeeded in doing just that with the new bio-based hardener Bayhydur eco 7190, which can reduce the carbon footprint of coatings formulated with it by roughly 30 per cent.

Coating furniture under extreme conditions RiFRA tested the first bio-based, waterborne, 2K polyurethane coating under extraordinary conditions. It exhibited very good mechanical and chemical resistance even in damp kitchen and bath environments. The company is currently presenting a line of designer furniture featuring the coating at the Salone del Mobile in Milan, Italy.

The bio-based, waterborne polyurethane dispersion Impranil eco opens up a new dimension in the sustainable coating of textiles. The newest product in Covestro’s INSQIN lineup, it offers an improved eco-balance over the entire life cycle of coated textiles while also helping to conserve water. Covestro is thus helping brand owners and textiles manufacturers to achieve their sustainability goals.

Unique design with DirectCoating Unique designs at competitive costs – this is Covestro’s aspiration for its DirectCoating technology. Carmakers want to meet customer demand for greater interior customization options even as they strive to increase productivity.

Covestro is presenting a number of visionary, and in some cases near-series, applications with these products at the European Coatings Show. “They are the results of close collaboration with partners along the entire value chain,” said Daniel Meyer, head of the Coatings, Adhesives, Specialties segment. “That underscores the strong industry interest in these developments.”

With the help of DirectCoating, coated plastic components can be produced in a single production step rather than the total of five forming and coating steps required by the conventional process.

DirectCoating can also reduce costs by up to 40 per cent and energy consumption by as much as 75 per cent. Covestro offers a complete package of coatings and plastics expertise.

First automotive coating with bio-based hardener The highlight of the Covestro booth is an Audi Q2. It is one of a number of test bodies to which a clearcoat containing a bio-based hardener was applied for the first time under realistic production conditions. The two-component coating was developed by BASF’s Coatings division.

New dimension of design freedom A successful joint project with Votteler Lackfabrik suggests that a breakthrough is imminent for DirectCoating technology. It can be used to create parts with new and attractive designs combining different shades, surface structures and haptic properties even on a single component.

CEW Press Release Global Push for Earth Observations Continues Geneva Switzerland: The Group on Earth Observations (GEO) has been working for more than a decade to open access to earth observation data and information, and increase awareness around their socioeconomic value. As GEO moves into the second decade four new global partners are announced to help support GEO’s vision.

The GEO community has been building a Global Earth Observation System of Systems (GEOSS) that links ear th obser vation resources worldwide across multiple Societal Benefit Areas (SBAs). These SBAs range from Biodiversity and Ecosystem Sustainability, Disaster Resilience, Energy and Mineral Resources Management, Food Security, Infrastructure and Transportation Management to Public Health Surveillance, Sustainable Urban Development and Water Resources Management. The SBAs serve as lenses through which the Member governments and Participating Organizations (POs) that constitute GEO may focus their contributions to GEOSS, with a goal to make the open EO data resources available for informed decision-making.

The four organizations include Conservation International (CI), Earthmind, Global Open Data for Agriculture and Nutrition (GODAN) and the United Nations Children’s Fund (UNICEF). Each organization has now joined GEO as a Participating Organization, taking the total number to 110 working internationally to advocate, engage and deliver on open EO data.

“CI empowers societies across the globe to sustainably care for nature through science and partnerships. We are excited to join the GEO community, which has long recognized the power of collaboration in leveraging earth observation to benefit humanity.”

Said Daniel Juhn, Senior Director, Integrated Assessment and Planning Program at Conservation International. “Though we face obstacles to achieve the SDGs, we are at a critical juncture where the science of valuing ecosystems, and understanding the full services nature provides to people expands our knowledge and options. We hope this partnership exemplifies bringing together that science, the right policies, necessary collaboration, and advanced technologies to generate the solutions we need to tackle global sustainability challenges.”

“Earthmind supports positive efforts by private, public and non-profit stakeholders to conserve and responsibly manage nature. As one of our main programmes is to recognise conservation in the areas where people live and work, we are most honoured and indeed excited to join the GEO community. In so doing, we hope to further encourage voluntary efforts to observe how we managing our planet in order to take better care for it.” said Francis Vorhies, Founder and Executive Director of Earthmind.

“GEO, its Members and the broad new set of tools provided by geodata constitute a fantastic step forward in the quest to help farmers from all corners of the world improve their yields and Governments to improve their policies to further stimulate agriculture in their respective countries. This is why GODAN is very glad to become part of GEO and to count the GEO partnership among the GODAN network. We believe that this collaboration will be most fruitful for 22 • April 2017

all parties involved” said André Laperrière, Executive Director of the GODAN Secretariat.

“UNICEF has learned through experience that problems that go unmeasured often go unsolved,” said Toby Wicks, Data Strategist at UNICEF. “We will work with the GEO community to link the needs of the world’s most vulnerable populations to a rapidly expanding set of data informed solutions, including GEOSS. This partnership signals an effort to build a world in which a near real-time understanding of risks and global challenges, particularly water resources management and disaster resilience, allows us to work harder and faster, for children.”

The key engagement priorities for GEO in the coming years involve using open earth observations to respond to a number of global policy issues. The priorities are tied to the Sendai Framework for Disaster Risk Reduction, the Paris Agreement on Climate Change and the United Nations 2030 Agenda for Sustainable Development. These new partnerships will complement existing ones and also help deliver in line with the GEO engagement priorities.

CEW Press Release Honeywell Generates High Demand for New Paper Tissue Measurement Technology New Delhi, India: Honeywell Process Solutions (HPS) today announced its award-winning Crepe Structure Measurement sensor has received overwhelming global acceptance from pulp and paper industry customers.

The new technology, which is unique to Honeywell’s Experion MX integrated quality control and process knowledge system, provides users with a tool to optimize creping in real-time for improved production quality and efficiency. This substantial change in paper tissue and towel production has gained rapid acceptance in the industry, and HPS has seen significant orders from paper manufacturers around the world. Some customers have even replaced their entire quality control system to reap the benefits of this new measurement tool.

Introduced less than two years ago, HPS’ technology has earned recognition within the pulp and paper industry, receiving two awards recently. In November 2016, the sensor won the bronze award for innovation at the annual conference of the French paper industry association (Association Technique de L’Industrie Papetière) in Grenoble, France.

Previously, Markku Kellomäki, HPS Senior Scientist, was awarded the Jasper Mardon Memorial Prize by the Technical Association of the Pulp and Paper Industry at its 2015 PaperCon Conference in Atlanta. The international organization presents this award for a specific technical achievement that makes a significant contribution to advancing the science and technology of papermaking.

“While it has been great to see the power of this innovation recognized with awards by leading paper industry associations, the best evidence of the sensor’s value is the demand we have seen and continue to see from producers,” said Marko Jämsén, leader of HPS’ pulp and paper business in Europe.

Sandvik Launches Thermocut System Mumbai, India: Sandvik has announced the introduction of an innovative new hot air-based cutting device that integrates into its Rotoform pastillation system to deliver perfectly formed pastilles from high viscosity melts.

The ThermoCut® system has been designed to overcome a problem commonly known as ‘angel hair’. This refers to the formation of threads during the pastillation of hot melt adhesives and resins, products that can have viscosities as high as 40,000 mPas. These threads or tails, created when the melt is deposited on the steel belt cooler by the Rotoform, can result in a less than perfect pastille shape with more dust pollution and increased c l e a n i n g r e q u i r e m e n t s. T h e d eve l o p m e n t o f t h e S a n d v i k ThermoCut system overcomes this to deliver a significantly better quality end product.

The system works by blasting a narrow jet of high pressure, heated air at the precise place where the droplets are formed between the Rotoform and steel belt. This powerful blade of hot air cuts the threads before they have chance to develop further.

As well as delivering a more stable production process with better quality pastilles, the use of ThermoCut equipment also eliminates dust pollution and reduces cleaning and maintenance requirements.

The ThermoCut tool has been specifically designed to work with Sandvik’s flagship Rotoform, a system widely used across the chemical industry for the production of pastilles directly from the melt.

The Rotoform system consists of a heated cylindrical stator which is supplied with molten product, and a perforated rotating shell that turns concentrically around the stator, depositing drops of the product across the whole operating width of the steel belt.

The heat from the pastilles is transferred to cooling water sprayed against the underside of the belt, resulting in quick, controlled solidification and a consistent end product.

CEW Features CASE STUDY

Innovative Commercial and Technical Solutions for CSG Produced Water Treatment Project The coal seam gas (CSG) exploration and appraisal activities by Santos in Narrabri, New South Wales (NSW), Australia results in produced formation water (PFW) that is stored in specially constructed double lined ponds.

Santos is seeking to treat this water for beneficial reuse in irrigation, dust suppression, construction and drilling, and emergency firefighting purposes. Santos have outsourced this requirement to Osmoflo under a hybridized build, own and operate model, which includes the design and delivery of a water and brine treatment plant (WBTP), and specialist operation and maintenance services for 3 yrs initially, with a possible extension to 5 yrs. The WBTP is containerized to allow demobilization and future possible re-deployment, and to find an appropriate balance between the often competing drivers of the projects technical objectives, and the commercial requirements of delayed and minimized capital expenditure.

The PFW and legacy brine has a wide salinity range of 18,000 to 51,000 mg/L and algae counts up to 8.8 million cells/mL These need to be desalinated to produce irrigation quality treated water of salinity <600 mg/L. Osmoflo has selected disc filtration followed by a microfiltration (MF) system as pretreatment prior to desalination through reverse osmosis (RO). The RO system has been designed with a two stage configuration with an interstage booster pump to allow variable water recovery from 55 to 70% depending on the PFW salinity. The brine from the RO system is further concentrated through Osmoflo’s Brine Squeezer (OBS) process which is an innovative, cost effective, ultra-high recovery RO process. The Brine Squeezer process is designed to concentrate the brine to a salinity >90,000 mg/L in order to minimize the brine volumes

of its kind for the CSG industry. It has been centered around a fit-for-purpose WBTP, where the design, construction and operation must comply with all applicable Australian Standards, good water industry practice and any related project approvals from the Government.

The payment structure has two principle components: • Operating Lease for the Facility (offbalance sheet as Osmoflo retains ownership and risk over the term).

This payment has ‘fixed’ charges under the operational lease and for the O&M services, and a ‘variable’ charge based on actual throughput.

• Lump-sum component for the Associated WTP Infrastructure – which is mainly the fixed or buried infrastructure. Osmoflo constructs and owns the Associated WTP Infrastructure until Practical Completion date and then transfers ownership to Santos on payment of the lump-sum fee.

WATER AND BRINE TREATMENT PLANT Pond Transfer and Feedwater Each pond will have a containerized pump station to transfer the water from the pond to the WBTP. The container will be bunded internally so that any leakage or spillage from flanged connections and pumps will discharge back into the pond.

The container also consists of the pond return pipework to allow discharge of washwater or final brine (via manual valve selection) to each cell from the WBTP. 34 â&#x20AC;˘ April 2017

The HDPE pump suction line extends to 2729 m into the cell from the pond embankment and is attached with polyethylene pipe floats to allow it to float with the pond water level. At the end of the suction pipe the intake strainer drops 1 m below the surface to minimize algae concentration in the raw water. Similarly, the return pipeline extends approximately 136 m into the cell and floats on the pond surface.

The HDPE pipework from the pond to the WBTP bunded area will be PN16 (>6 times more than the maximum operating pressure) and there will be no flanged

connections or air release connections in order to mitigate risks of leakage to the environment.

Site Facility The WBTP site (refer to Figure 1) will be located on a new earthworks pad and the treatment process areas will be fully bunded to contain any spillage or leakage of PFW, brine or chemicals and allow controlled discharge of rain water. The bunding is achieved with geosynthetic clay liners on top of compacted sandy clay and is at 800 mm height at the top level of the Chemical Engineering World

bund. The bund surface will have a rubble finish. The chemical storage and loading area on the southern side of the bund will be sealed with 40 mm asphalt surfacing with heavy duty binder. Gradient within the bund is towards closed sumps so that any overland flow, including rain water, can be tested and confirmed to be harmless before release.

Water storage tanks within the bund will be heavy duty polyethylene tanks with multiple modes of tank level detection to minimize the risk of overflow. These include tank level transmitter with high level shutdown interlock, high level switch in the tank and a high level switch in a sealed (from rain) drum where the tank overflow is directed into.

The majority of equipment is containerized, which will minimize on site construction. All containers will have drip drains where all drain and sample lines are directed into. The drip drains will be piped to sumps to prevent uncontrolled spillage into the bund.

Other major infrastructure outside of the bund includes generators and a treated water storage tank that is a 5,000 kL bolted modular panel tank with plastic liner. Power generation is an important part of WBTP as power is a major part of the operating costs. It has been designed with three generators. The 1400 kW generator is a containerized reciprocating gas engine that supplies all the necessary 36 • April 2017

power with spare capacity. It uses fuel gas from Santos’ CSG operations to significantly reduce the operating costs of the WBTP. The 656 kW and 240 kW diesel generators are backup generators.

Water Treatment Osmoflo’s extensive experience of membrane filtration and RO treatment of CSG produced water was a key to ensuring robust and flexible treatment design with high level of automation. The high algae counts in the pond water ensure the need for a robust pretreatment process and could be compared to the issues of dealing with algal blooms in seawater RO desalination. Laboratory analyses showed that the algae are of small particle size mostly <150 µm. The legacy brine had the highest counts (up to 8.8 million cells/ mL), the PFW in the pond has high counts (mostly <1 million cells/mL) and the PFW water in the pipeline feeding the ponds had the lowest counts (<20,000 cells/mL).

Osmoflo wanted to keep the treatment processes simple including pretreatment and decided to reduce the algae counts of the feedwater by blending the sources of available water. This facilitated selection of membrane filtration as pretreatment without the need for more extensive pretreatment such as dissolved air flotation. Pall microfiltration (MF) equipment was selected as it had a track record in treating similar produced water and that it could treat up to

The high algae counts with the high organic levels combined with the fact that CSG produced water tended to have high biofouling potential meant the pretreatment design needed to include for disinfection. A provision for shock dosing of three different biocides has been included to mitigate biological fouling in the RO process. These include isothiazolinone, Kuriverter IK-110 (Kurita Industries) and DBNPA (2,2-dibromo3-nitrilopropionamide) and ensures that the ‘bugs’ do not become tolerant to one particular biocide. In addition, manual shock chlorination of the pond transfer pipelines to disinfection these pipeline has been provisioned.

The feedwater blending also has the benefit of reducing the TDS variation between the PFW and legacy brine. The RO system, called Primary RO (PRO) is designed as a two stage concentrator with interstage booster to allow flexibility in treating the variable feed water TDS and temperature and ensure the highest recovery possible while distributing the membrane flux properly to minimize fouling. The PRO recovery will vary between 55 and 70 per cent for the blended feed water. The PRO system consists of two trains for some level of redundancy similar to the pretreatment.

Treated water from the PRO (called PRO permeate), blended with the permeate from a polishing brackish water RO (BWRO) system that desalinates the Brine Squeezer permeate is dosed with calcium chloride. The calcium chloride Chemical Engineering World

increases the calcium in the blended permeate and ensures the sodium adsorption ratio (SAR) or sodicity is <5 and suitable for irrigation.

Brine Treatment It is expected that the PRO will produce a brine TDS of 70,000 mg/L while contractual obligations require >90,000 mg/L for the final brine TDS. One of Osmoflo’s key strength in securing this contract was the use of the in-house developed and patented Brine Squeezer process to reduce the RO brine reject volumes cost effectively. It has been demonstrated in two applications to increase the overall plant recovery 9295 per cent from 70-75 per cent resulting in only 5-8 per cent brine to dispose of. The Brine Squeezer (OBS) process incorporates many existing and available equipment and learned techniques to manage and mitigate fouling and scaling of increasingly concentrated brine streams - with some innovative features and techniques including: • • •

Use of unique combination of membrane properties Use of sacrificial coating (when required) to manage fouling and scaling Use of innovative cleaning strategies to effectively clean foulants/scales.

40 • April 2017

Other simple features to manage fouling and scaling include operation at high crossflows, low fluxes and higher ionic strength.

The OBS is expected to produce a brine concentrate 100,000-120,000 mg/L and in blending with the small amount of PFW or legacy brine remaining in the ponds the final brine TDS of >90,000 mg/L is able to be achieved. The higher final brine TDS allows for more costeffective further concentration and salt recovery as part of the CSG industry’s vision for beneficial reuse of salts and solids disposal offsite.

The OBS system has the highest level of automation, intelligently adjusts operating parameters for the higher fouling and scaling conditions and automatically cleans the membrane. Frequent CIPs are expected and the membranes are used as a semi-consumable as they are operating outside the normal boundary of RO. The innovative hot water CIP technique on the OBS will easily remove biofouling, organic fouling and some of the scaling.

The unique sacrificial coating will only be used to enhance scale removal and reduce CIP chemicals.

Solids Dewatering DAF and centrifuge were selected for solids dewatering due to proven tracking records in algae laden water and flexibility in handling variations in flows and solids concentration. The jar testing correlated that the use of filtered feedwater (same ionic species as the PFW or legacy brine) for backwashing the MF (which forms the majority of the solids to be dewatered) will cost >$200,000 per month in chemicals in the dewatering process. This was costly and a more cost-effective design of using the permeate from the OBS for MF backwashing was developed. The significant lower TDS and alkalinity of the OBS permeate are expected to significant reduce the chemical consumption from extensive field experience.

The DAF design incorporates a conservative detention time of approximately 30 mins for coagulation to ensure adequate reaction time since experience indicated algae are one of the more difficult types of solids to coagulate.

The hydraulic loading of the whole DAF has been sized conservatively so that there is a 40 per cent contingency over the normal feed flow.

The centrifuge has also been sized conservatively to treat the DAF sludge under 16 hours and incorporates an automatic greasing which will reduce maintenance frequency and effort. It is designed to produce a sludge cake of 18-20 per cent dry solids that is suitable for disposal off site via trucking.

CEW Features CASE STUDY

WSSC Achieves Over 60% Reduction in Hydraulic Plan Review for Water and Wastewater Systems Helped complete hydraulic plan analyses more efficiently than WSSC’s in-house system Hydraulic Plan Review Scope Washington Suburban Sanitary Commission (WSSC) Development Services Group reviews hydraulic plans for approximately 160 proposed development plans per year. This includes water and sewer system extensions as well as approximately 172 small-site utility plans (commercial private systems) that connect to the existing water and sewer network in two large Maryland counties.

Each system extension is hydraulically reviewed and mains are properly sized

by WSSC hydraulic engineers during the hydraulic plan analysis (HPA) process. In this process, engineers use hydraulic-grade benchmarks developed by the planning group within the existing system to analyze the proposed extensions and connections.

These benchmarks are developed using system-wide modeling while considering the severest conditions in the system.

The WSSC hydraulic engineers determine the appropriate sizes for the proposed mains while considering various scenarios that focus on the system integrity and future needs to provide adequate fire flow and pressure to new developments.

When the creation of a new pressure zone is sometimes required to serve a new development, the hydraulic reviewer interacts with the planning group that models the system-wide network to help with zone creations.

The project’s overall goal was to increase customer service levels by implementing a workflow process improvement. To meet

this goal the Development Services Group implemented Bentley’s WaterGEMS and SewerGEMS to increase the turnaround time on reviews and keep pace with one of the most rapidly developing areas in the United States. The reviews were critical to the success of the projects as they serve as the primary planning mechanism for growth.

Increased Review Efficiency Prior to using WaterGEMS and SewerGEMS the Development Services Group completed the hydraulic plan analyses with small-scale software developed in-hozuse that was less advanced and less user-friendly. Using WaterGEMS and SewerGEMS, as well as group restructuring, the Development Services Group increased review efficiency through a standardized model between projects, improved quality assurance of

reviews, and reduced review cycle times from an average of 73 days to 27 days for moderately complex projects over eight years, despite a two-fold increase in reviews.

The following examples illustrate review time improvements: • WaterGEMS and SewerGEMS’ scenario and alternative capabilities allows organized and systematic modeling, so that other reviewers are able to use the model from where the original reviewer left off. And because model scenarios are created for each development phase of a project phase, each project can be reviewed for hydraulic integrity and adequacy easier and faster. This means that the developers who choose to move forward with a partial release of project phases can receive a quicker response from WSSC. • Environmental issues can also cause development engineers to re-consider alignments midway through the design process. Because hydraulic engineers have developed consistent models for each proposed development and system extension, the amendments to original alignments can be rapidly adjusted and re-analyzed. This means development engineers can make changes based on environmental issues more quickly and with less review time.

44 • April 2017

•

The Development Services Group can also be more responsive to system inspection changes during the construction process as they have access to the completed models.

On a larger scale, the increased review efficiency is improving customer service and the overall delivery speed of an estimated 160 annual development projects from planning and design phases to constructionready status. And because construction began sooner, revenues (through permit fees or new billing accounts) were collected sooner.

Reduced Project Deliver y and Operation Costs WaterGEMS reduced the time needed to accurately size pipes to meet WSSC’s system constraints and standards. This resulted in faster communication and turnaround to consultants and developers.

As WSSC can process development reviews more quickly, the organization can expedite its revenue collection by allowing more customers to connect to the system sooner.

Safer Water and Sewer Infrastructure Adequate fire flow is essential for safety. The fire flow capability in WaterGEMS enabled reviewers to perform fire flow analysis for numerous locations throughout a large or small network used for a project in a single run. Reviewers could model multiple scenarios under various system outage conditions, including routine inspections of large diameter pre-stressed concrete cylinder pipe (PCCP) mains, to optioneer the best solution that allows adequate fire protection.

Using SewerGEMS also enabled WSSC to analyze system issues in wastewater infrastructure during the development process. This resulted in a better quality hydraulic design and ultimately protected the environment from future sanitary sewer overflows in new development areas.

Information Mobility Increased Collaboration Workflows have been developed to help streamline collaboration between engineering, GIS, and consultants. For instance, simple GIS capabilities and the Model Builder functionality in WaterGEMS and SewerGEMS allowed reviewers to incorporate proposed pipelines within a development with existing pipelines in WSSC GIS container. WSSC improved workflow efficiency with more than an estimated 60 per cent reduction in review cycle times for hydraulic analyses of development and system extensions.

Author’s Details The use of WaterGEMS and SewerGEMS has also enabled the Development Services Group to spend less time modeling and analyzing a larger network of the system, identify problem areas

Explosion Hazard and Safety in Industries Handling Metal and Alloy Powders Some of the metal and alloy powders handled in industries manufacturing and using these are combustible and have inherent explosion hazard. This article presents explosion parameters – minimum explosible concentration, maximum explosion pressure, deflagration index, minimum ignition energy and minimum ignition temperatureof 25 materials- aluminium paint ground, aluminium-grit, aluminium-iron alloy (50:50), aluminium-nickel alloy, bronze, calcium-aluminium alloy (50:50), calcium-silicon alloy (50:50), calcium-silicon-aluminium alloy (30:50:20), calcium-silicon-barium alloy (30:50:20), copper-silicon alloy, ferrosilicon, ferrochromium, ferromanganese, iron, iron-silicon-magnesium alloy, magnesium-silicon alloy (60:40), neodymium-iron-boron alloy, nickel-aluminium alloy, silicon, steel(100 Cr6), tantalum, tantalum-niobium alloy, titanium, titanium-niobium alloy and zinc - measured with CSIR-CBRI 20-L sphere, Hartmann apparatus and Godbert-Greenwald furnace for a range of particle sizes (74,37,22 and 10µm). The data may be used for evaluating explosion hazard involved in their manufacture, transport, storage and use and designing explosion safety measures.

T

he powder metallurgy industry has grown over the past few years due to economic gain in manufacturing net-shaped components in comparison to conventional metal working methods like casting. Many of the metal and alloy powders processed in these industries are combustible and pose explosion hazard in various powder metallurgy related activities and other metal working operations eg. material charging, grinding, sieving, milling, dust collection, casting, pneumatic transport, machining, welding, etc. Dust explosion may occur in these units/areas due to simultaneous presence of explosive dustair mixture and potential ignition source viz. electrical or mechanical spark, static electricity discharges, hot surfaces, etc.

It takes only microseconds for a violent explosion to occur in a confined space.

Subsequent rise in explosion pressure can have devastating consequences.

The explosion parameters for identifying probability and severity of dust explosion and designing explosion safety measures are: minimum explosible concentration (MEC), maximum explosion pressure (P max), rate of rise of explosion pressure Chemical Engineering World

((dP/dt) max), deflagration index (K St), minimum ignition temperature (MIT) and minimum ignition energy (MIE). The explosion characteristics of number of dusts handled in industries are available for some particle sizes (Eckhoff, 1991; BIA,1997). However, there is always a need of measurement of explosion characteristics of dusts with specific sizes. The present work reports the explosion characteristics of various metal and alloy dusts for a range of particle sizes measured at CSIR-CBRI. The information and data from this study add to the current literature on explosion characteristics of dusts processed in metal industries and will be used to evaluate explosion hazard of units/areas handling similar dusts and designing the explosion safety measures.

Experimental Procedures The explosion characteristics were determined for 25 dusts- aluminium-paint ground, aluminium- grit, aluminium-iron alloy (50:50), aluminium-nickel alloy, bronze, calcium-aluminium alloy (50:50), calcium-silicon alloy (50:50), calciumsilicon-aluminium alloy (30:50:20), calcium-silicon-barium alloy(30:50:20), copper-silicon alloy, ferrosilicon,

ferrochromium, ferromanganese, iron, iron-silicon-magnesium alloy, magnesium-silicon alloy (60:40), neodymium-iron-boron alloy, nickelaluminium alloy, silicon, steel(100 Cr6), tantalum, tantalum-niobium alloy, titanium, titanium-niobium alloy and zinc. The particle sizes of dusts selected for study are: 74, 37, 22 and 10 µm.

Samples for particle sizes 74 and 37µm were prepared using traditional sieve analysis. Other samples were collected from manufacturers. Some dusts were investigated for all the particle sizes chosen while others for limited sizes.

Explosion indices- MEC, P max and (dP/ dt) max were measured in 20-L Sphere (Mittal, 2012) consisting in a spherical combustion chamber, a dust storage container connected with chamber via a dust outlet valve, a pair of electrodes holding two pyrotechnic ignitors at sphere centre, and two piezoelectric and one strain gauge pressure sensors to record explosion development. Typical pressure-time curve recorded during dust explosion experiments is shown in Figure 1. Pressure trace starts at partially evacuated value of 0.4 bar(a). The blast April 2017 • 49

of air that disperses dust starts at 40 ms and ends at 90 ms on pressure-time trace. Ignitor is activated at 100 ms at a chamber pressure of 1.0 bar(a). P ex is the maximum explosion pressure. Value of P ex, for a test at a given concentration, is highest deflagration pressure (absolute) minus pressure at ignition (normally 1 bar). (dP/dt) ex is maximum rate of pressure rise reached during the course of explosion.

MEC, the lowest concentration of dust in air that ignites on contact with an ignition source and propagates a dust explosion, is determined following the standard procedure (ASTM, 2007a) using chemical ignitor (2.5kJ energy). The test commences with experiments at a high powder concentration. If this concentration of powder ignites, dust concentration is reduced in steps until no ignition is evident.

An ignition is deemed to have occurred if maximum explosion pressure is at or above 2 bar(a). The test is then repeated with a lower dust concentration which is reduced further until a concentration is reached at which no ignition of dust/air mixture is observed in three consecutive tests.

Explosion severity measurement experiments are conducted over a range 50 â&#x20AC;˘ April 2017

of dust concentration in accordance with standard procedure (ASTM, 2010).

Pyrotechnic ignitors (10kJ energy) are used. P max is maximum pressure and (dP/dt) max is maximum value for rate of pressure increase per unit time reached during the course of explosion for optimum dust concentration and equals maximum slope of a tangent through the point of inflexion in rising portion of pressure vs. time curve. Deflagration constant, K St, characterizing explosibility of the material is maximum value of dP/dt normalized to 1.0 m 3 volume measured at optimum dust concentration and defined by equation 1 (Eckhoff, 1991):

where, P - Pressure, bar T - Time, s Vs - Vessel volume, m 3 KSt- Dust deflagration index, bar.m/ s K St values rounded to nearest integer are used. Dusts are given explosion severity classifications St1 (K St<200 bar.m/s), St2 (200 bar.m/s >K St <300 bar.m/s) and St3(K St>300 bar.m/s).

MIE, used to represent the ease or difficulty of powder ignition by electrical sparks

and arcs or electrostatic discharge was measured in 1.2-L Hartmann apparatus as per standard procedure (Mittal, 1996; ASTM, 2007b). The apparatus consists of a glass tube placed over a dispersion cup and fitted with two brass electrodes (3 mm diameter, 2-6 mm spacing) connected to a spark generating system having three units: variable capacitor bank; variable voltage supply/ continuous spark unit; and step-up transformer. With variable combination of capacitance and voltage, it is possible to obtain sparks with ignition energies in the range 0.5 mJ â&#x20AC;&#x201C; 3.2 J using this circuit. There is precise electronic synchronization between dust dispersion and spark onset. The ignition delay times can be selected between 20 to 200 ms with an increment of 20 ms.

Energy discharged from the capacitor is calculated from the following formula (2)

Where, W - Discharge energy, J C - Total capacitance of discharge circuit, F V i - Initial voltage of charged capacitor, V V f - Final voltage of charged capacitor, V To establish MIEs, the tests are done by starting at relatively high spark energy levels using relatively large discharge capacitance which is reduced in steps until no ignition occurs for ten ignition trials. A weighed sample of dust is placed in dispersion cup. A blast of compressed air is used to disperse the dust in the glass cylinder where it is ignited by spark between two electrodes. Ignition trials of this dust-air mixture are attempted, after a specific ignition delay time, by spark discharge from the charged capacitor.

The stored energy discharged into the spark and occurrence or non-occurrence of flame is recorded by visual observation of flame propagation away from the spark gap. If flame propagation is observed, the energy of the spark is reduced until no flame propagation is seen for Chemical Engineering World

Features CEW ten consecutive tests. The minimum ignition energy is sought by varying dust concentration, spark discharge energy and ignition delay time. Experiment is started with a dust loading corresponding to dust concentration twice as high as the experimentally determined MEC or 250-500 g/m 3 and â&#x20AC;&#x2DC;go/no-goâ&#x20AC;&#x2122; spark energy is estimated. Once a limit is found for a particular dust concentration, the procedure is repeated for higher and lower dust concentrations until a roughly parabolic curve is obtained for ignition energy verses dust concentration.

MIE is determined from the MIE vs. concentration curve.

Figure 2: Maximum explosion pressure for metal and alloy dusts

MIT, lowest temperature of a hot surface that will cause a dust cloud to ignite and propagate flame, determines temperature classes of electrical equipment. GodbertGreenwald furnace (heated section: 3.9 cm diameter, 23 cm long, 0.27 l volume) was used to measure MIT as per standard procedure (Mittal, 1996; ASTM, 2006).

The initial tests are carried out at dust concentrations at which the maximum pressure, P max, and the maximum normalized rate of pressure-rise, K St, are found. The dust is placed in a dust holder at the top of temperature controlled furnace with an open bottom. Temperature of the furnace is set at a predetermined value.

The dust is dispersed by the compressed air downwards past the hot surface of furnace to see if ignition occurs and flame is produced. Ignition is defined as the flame exiting from furnace chamber.

Furnace temperatures, as well as dust concentrations are varied to ensure that auto ignition temperature is measured at most easily ignitable concentration.

Results & Discussions The MEC values measured for the dusts ranged from 20 to 400 g/m 3. These are given in Table 1 and can be used for evaluation of probability of explosion in a stated dust-air environment.

CEW Features all sizes of dusts. Pressure-time curves were recorded. Experimental curves were analysed and values of P ex, (dP/dt) ex and K St(=dP/dt)ex.V 1/3 were estimated for each experiment. The values of P max and K St corresponding to optimum dust concentration were determined for each particle size. The Pmax and KSt values at optimum dust concentration for dust particle sizes studied are presented in Figure 2 & 3. These figures indicate that P max and K st both increase significantly with decreasing size of dust particles from 74 to 10µm.

Explosion severity experiments examine consequences of dust explosion.

Maximum explosion pressure (P max) and pressure-rise rate, (dP/dt) max, describe violence of combustion of dust-air mixture in a closed vessel. The dust deflagration index is used to describe the severity of explosion increasing from dust explosion class St1 to St3. Figure 3. shows maximum explosion pressure for the dusts varies from 6.4 to 12.8 bar.

The deflagration index values presented in Table 1 indicate explosion class of dusts as: St1- aluminium grit (74 µm), aluminium-iron alloy (37 µm), bronze (10-22 µm), calcium-silicon-aluminium alloy (37-74 µm), calcium-silicon-barium alloy (10-74 µm), copper-silicon (1074 µm), ferrosilicon, ferrochromium & ferromanganese(10-22 µm), iron (10-37 µm), iron-silicon-magnesium (10-22 µm), neodymium-iron-boron alloy(22-74 µm), nickel-aluminium alloy (37 µm), silicon (10-22 µm), steel (2237 µm), tantalum (10 µm), tantalumniobium(10-22 µm), titanium(22-74 µm), titanium-neobium (10-22 µm) and zinc (10-37 µm); St2 - aluminium-iron alloy (10-22 µm), aluminium-nickel alloy (22 µm), calcium-aluminium alloy (37 µm), calcium-silicon alloy (22-74 µm), calcium-silicon-aluminium alloy (10-22 µm), magnesium-silicon alloy (22-74 µm) and nickel-aluminium alloy (10-22 µm); and St3- aluminium paint (37-74 µm), aluminium grit (10-37 µm), aluminiumnickel alloy (10 µm) and calciumaluminium alloy (10-22 µm). Out of 25 52 • April 2017

dusts examined, 16 are St1; 2 are St2; 1 is St3; and 3 are St1 & St2, 1 is St1 & St3, 2 are St2 & St3 depending on particle size.

MIEs were determined for 12 dusts for their various particle sizes over a range of dust concentration following the procedure explained above. Experimental results on MIE measurement are presented in Table 1. The minimum value of MIE was <1 mJ for 22µm titanium. The experimental data indicate that ignition sensitivity increases (MIE decreases) when moving from higher size to lower micron-particle dust clouds.

The MIT is an indication of the sensitivity of a dust cloud to auotoignite at elevated temperatures. The MIT for each particle size of dust was determined in GodbertGreenwald furnace starting with dust concentrations at which the maximum pressure P max, and the maximum normalized rate of pressure-rise, K St, were found as per standard procedure.

Experimental results are presented in Table 1. MIT decreases with decreasing particle size, increasing the probability of explosions with small-sized particles over larger particles. The MIT for the dusts tested ranged from 270 to 950 oC. The experimental values of MEC, Pmax, KSt, MIE and MIT for the dusts studied in present investigation are in close agreement to that published for dusts having sizes closer to that involved in present study (Eckhoff, 1991; BIA,1997).

Explosion Safety Measures- Overview Control of explosion hazard in industries manufacturing/handling metals and alloys should involve: evaluation of material processed; identification of areas/units susceptible to formation of combustible dust-air mixture; and defining parameters including the explosion characteristics of powders handled forming the basis of safety measures for various unit operations early in the project or process life cycle; and communication of hazard and control strategy to personnel involved in various plant operations and other concerned persons.

The explosion characteristics are used for designing explosion prevention - control of dust cloud concentration (equipment maintenance, local exhaust, ventilation, and housekeeping) and control of ignition source and explosion mitigation measures- explosion venting, explosion suppression, explosion isolation and containment. Every equipment has a list of safety measures depending on explosion/safety characteristics of the powders being handled.

Explosion suppression system is designed to detect the pressure wave/ flame at very start of an explosion and deliver dry, inert chemical extinguishing agents into a developing initial deflagration. The suppression system can be activated either by pressure, optical or vent sensors. Any deflagration travelling through interconnected equipment is quickly and efficiently extinguished, preventing any spreading explosion damage. Venting is passive method to relieve explosion pressure in a confined unit containing combustible material. Open venting is not the popular choice in industries. Flame-quench vents may be used for venting the explosion.

Mechanical isolation is a cleaner means of explosion protection. Explosion pressure is determined by use of isolation valves. When an explosion actually occurs, the pressure travels into a single or double acting valve which seals the pressure wave inside the valve and prevents it from spreading through the equipment.

The safety measures are designed in accordance with standards (NFPA,2013,2014,2016, 2017b).

In explosion-prone areas having probability of dust explosion outside the process units, it may be recommended to provide explosion venting or blast resistant walls as per building codes and an electrical area classification should be used as per standard (NFPA, 2017a) Chemical Engineering World

CEW Features Conclusions Explosion hazards associated with metal and alloy powders influence the specifications of operating procedures, equipment, air conditioning systems, electrical area classification and room construction, etc. It is therefore necessary for metal/alloy manufacturers to understand the explosion hazard of the powders handled in their facilities and assess the level of deflagration risk.

Dust explosion data specific to metals and alloys for different sizes of dusts is a powerful tool in explaining the real risk from explosions to those managing and operating these facilities. The information and data presented may be used for designing explosion safety measures for units/areas handling similar types of dusts.

New Marine Breakaway Coupling

T

he Mar ine2 launched by KLAW is 32 per cent shorter and 25 per cent lighter than alternative Marine Breakaway Couplings on the market and is designed to reduce stress on hoses used on offshore hose reel applications.

The shorter design as shown in illustration A reduces coil disruption on the hose reel; unlike alternative designs (illustration B) that are longer and therefore increase hose stress and fatigue.

The KLAW Marine Breakaway Coupling provides a safe parting point within the hose transfer system in ship-to-ship, shipto-shore and vessel to offshore platform transfers. The coupling is designed to activate in an emergency such as vessel drift in stor my conditions or pressure surge. When activated, the valves within the coupling shuts both upstream and downstream flow within the hose transfer system and allows immediate separation of the line.

The KLAW Marine2 therefore minimises risk of spill and reduces the risk of

damage to assets, injury to personnel, extended downtime and contamination of the environment.

Like its KLAW predecessor, the Marine2 is designed to resist those bending moments and torsional forces expected f r o m f l o a t i n g wave m o t i o n s a n d t h e rigours of the marine environment and reacts only to those axial forces that occur in an emergency.

The KLAW Marine2 also continues to use the proven and reliable KLAW Flip-Flap Valve system which delivers 100 per cent instant closure.

KLAW Easy Reset Facility is also fitted as standard on the Marine2 which means the coupling can be serviced or reset after activation within the line – again reducing downtime and stress on the hose due to the reduced need for additional handling.

Marine2, the new KLAW Marine Breakaway Coupling, is 32% shorter and 25% lighter than alternatives and has been designed to reduce stress on reeled hoses.

Reverse Osmosis and Ion Exchange – Unique Process Steps to Minimize the Liquid Discharge

T

he application of water treatment technologies to achieve minimal liquid discharge (MLD) or zero liquid discharge (ZLD) is increasingly under consideration in today’s water stressed world. MLD and ZLD are processes that minimize or eliminate the discharge of water or liquids from a plant process. The reasons to implement these processes can be;

compounds. Another technology that can be used is ion exchange treatment (IX). This technology should be applied if a selective separation is preferred, eg, to remove specifically some ionic contaminants from the process water or to recover valuable ionic or non-ionic substances selectively.

This separation can be achieved using a special IX product called scavenger, selective resin or adsorber resin.

Regulatory Cost saving from water recycling, and reduction of water discharge costs Environmental - Increase sustainability of industrial sites in water stressed regions

When interception technology is not possible, the client should consider an end-of-pipe treatment solution. In this case, the plant wastewater is collected and treated depending on the type of c o n t a m i n a n t s by e i t h e r m e c h a n i c a l , biological, or filtration steps to produce a water quality that can be reused in an upstream plant process.

•• ••

••

T h e r e a r e t wo t r e a t m e n t o p t i o n s fo r process water: internal recycling and the end-of-pipe treatment.

The internal recycling is conducted inside the plant processes, and implemented by analyzing the water composition and the water quantity to make a so-called “pinch point” analysis. In this analysis, the water quality and water quantity are determined for a specific production step, and a decision is made as to whether it is possible to use the wastewater from a certain production step as the water supply for a separate production step. If usage is not possible, an interception technology may be used to get the water quality to the level suitable so that it can be reused.

A typical technology for this is membrane technology. Depending on the type of contaminants, it can be microfiltration (MF) to remove bacterial substances, ultrafiltration (UF) to remove particulate a n d h i g h m o l e cu la r we ig h t o rg a n ics, nano-filtration (NF) to remove divalent salts and organics, or reverse osmosis (RO) to remove salts and small organic 56 • April 2017

In MLD/ZLD processes, it is common that both interception and end-of-pipe treatment options can be applied for overall wa t er management. Whic h treatment process is adopted usually depends on the size of the plant, and whether the treatment process is added to an existing plant. If an MLD/ZLD process implemented to an existing plant, in most cases an endof-pipe treatment is preferred since less new piping, and less interference with the existing process is required.

In the following industrial examples, two MLD (minimal liquid discharge) processes, which were implemented in existing plants in India, are presented. These examples represent two different industries: the textile and the chemicals industry.

Chemical Industry This zero liquid discharge wastewater treatment plant is located inside the wa t e r t r e a t m e n t fa c i l i t y s e c t i o n o f a

m a j o r s p e c i a l t y c h e m i c a l s p r o d u c e r.

The wastewater plant processes treated s ewage water v ia UF ( u ltra filtra tio n ) pretreatment, cartridge filtration, and RO membrane desalination. The desalinated water is further treated by degasification, and ion exchange mixed bed columns installed with Lewatit MonoPlusS108H and MonoPlusM800 to prepare boiler feed water. The RO installation is a two-stage system with a capacity of 38 m 3/h. The feed water to the RO has a TDS in the range of 600–1,300 mg/l. The permeate has a TDS below 20 mg/l, and after mix bed application, a final boiler feed water quality of < 0.1 mg/l TDS and 0.02 mg/l silica.

The concentrate is fur ther treated by high pressure RO. The permeate of this concentrate RO is reused in the process, and finally the brine concentrate is treated via an evaporation step to achieve the zero liquid discharge operation.

Marketing Initiatives The aim of this MLD process was to reuse the process water and recover y of the salt to •• Save feed water costs •• Realize cost savings by recovery of the •• Produce less waste T h e k e y t e c h n o l o g i e s t o a c h i ev e a water quality, which could be reused in the process, were the application of a scavenger resin, a softening resin process, and a reverse osmosis process.

Membrane Performance The water treatment installation was o r i g i n a l l y d e s i g n e d a r o u n d “ u l t ra l ow energy” seawater RO elements. However, after three years, these elements were replaced with Lewabrane RO B400 HR elements since a performance projection ( p r e p a r e d w i t h t h e L ewa P l u s d e s i g n software) showed that the required permeate quality could be achieved with standard test pressure BW elements operating at an even lower feed pressure.

After start-up, the predicted performance advantages of the Lewabrane BWRO membranes were confirmed during routine daily operation. The RO feed pressure with Lewabrane RO B400 HR was throughout t h r e e ye a r s b e l ow 9 . 5 b a r ( w i t h t h e previous SWRO elements feed pressures were on average12 bar). The RO system salt rejection was approx 98.6 per cent (as compared to the 97.3 per cent rejection achieved with the SWRO elements). The new Lewabrane elements also provided an increased silica rejection (from 94 to 96.6 per cent) resulting in an increase of the cycle time between regenerations for the mixed bed ion exchange system. After three years in operation (with monthly cleaning), the RO system rejection level is still in the order of 97.5 per cent. Recently, the first stage Lewabrane RO elements were Chemical Engineering World

replaced with a Fouling Resistant Type (Lewabrane RO B400 FR) incorporating a 3 4 m i l fe e d s p a c e r ( r e c o m m e n d e d for wastewater application), which has resulted in a reduced cleaning frequency.

Textile Industry The second industr ial example is a n i n n ova t i ve p r o c e s s i n t h e t ex t i l e industr y. The dying process requires high concentrations of salt to fix the dyes on to the cellulose textile. At the end of the process, the wastewater stream consists of a high concentration of salts and organics. Discharging the untreated wastewater would not only be harmful for the environment, it may also impact existing drinking water sources. Since the textile industry is an important employer, the Indian government strongly supports projects with MLD processes.

In this process, the wastewater is first treated with a biological treatment (tertiary treatment) to reduce the amount of organics in the wastewater. This step is followed by quartz filtration. The process water is then passed through an ion exchange treatment stage consisting of a scavenger resin to remove the organic substances, followed by high TDS water softening. Since sodium sulphate is added during the process, calcium must be removed to avoid the precipitation of calcium sulphate.

After the ion exchange sequence, the water is passed through a reverse osmosis system to remove salt and other remaining organics. The RO system operates at a recovery rate of 80 per cent. The RO br ine reject is fur ther treated by NF (nano-filtration) membranes to recover the sulphate, while the sodium chloride, which passes through the NF membrane, i s c o n c e n t ra t e d by a mu l t i p l e e f fe c t evaporator. Sodium chloride salts are

finally dried in a solar pan (as solid waste).

The concentrated sulphate from the NF process step is reused in the process.

The efficiency of the different treatment steps can be seen in Table 2.

The MLD treatment process is extremely efficient, and this underlines the advantages of an ion exchange pretreatment for an RO process. The lifetime of the RO elements in this process is 3-4 years, with the added benefit of reduced COD content from the scavenger resin treatment step to reduce the potential of bio-growth.

Conclusion Th e above industr ial ex amples show that the reduction of wastewater, even in challenging process industries is possible using the right tools. Ion exchange and reverse osmosis is a smart and efficient combination to treat wastewater with a high organics load and high salinity.

Even with wastewater as feed solution final water quality, that can be used for boiler feed water, can be achieved by the combination of an RO system followed by polishing ion exchange mix bed.

organics from the wastewater that can pass through an ultrafiltration process and lead to potential biofouling in the RO process.

Finally, for MLD/ZLD processes, it must be noted that it is often challenging to achieve standards, but innovative combinations of existing technologies make it possible to reach the targeted goal.

The use of scavenger resin as a pretreatment before RO should be considered, to remove

Level Switch Coat-Endure-T is an innovation resulting from an unmet need of a compact coating immune admittance based level switch. Whereas compact vibrating forks for liquids have proven to be very successful for space constrained silos; slurries and pastes tend to be sticky, where vibrating forks could malfunction due to a coating of application material.

Coat-Endure-T is an improvement over traditional principle of admittance such that the coating immunity is controlled by the on-board microcontroller and can be adjusted easily. Suitable for both conductive and nonconductive media, the sensor is immune to fluctuations in process parameters like temperature, dielectric constant of the media and variable build-up patterns. It allows material independent calibration, faster installation and commissioning, and offers an easy to clean tri-clamp mounting for hygienic applications.

The sensor works well with powders, solids, liquids, pastes and slurries, and comes with RoHS compliance.

Products CEW Densify Screw Feeder The densifying screw feeder is offered where the product to be bagged is fluidised. Density of such material is very low owing to entrapped air in the product. Such products are very difficult to handle owing to highly free flowing characteristics of the product. Due to low density of the product and high quantity of entrapped air, such products require bigger size of bag to accommodate the given weight of the product. The densifying screw feeder removes entrapped air from the product. Density of the product thus increases sufficiently enough to accommodate this material into the given size of the bag. However, some percentage of air still remains inside the product which controls the flow-ability of the product.

Paddlewheel Flow Meter Malema’s paddlewheel (also called Tangential turbine) flowmeter line utilises sophisticated circuitry to foster signal conditioning, resulting in flowmeter systems that are smaller, easier to install and more accurate than ever before. Paddlewheel flow meters continue to be the most common way to measure flow electronically in a wide range of industries.

The rotational velocity of the rotary wheel varies linearly with the average velocity of the fluid flowing through the flow meter. A square wave pulse is generated from magnets embedded in the vanes of the rotor wheel. Depending on the output version of the M-10000, the pulse signal is relayed directly, converted to a 0-10 V DC output or a 4-20 mA output. The voltage and current models are span adjustable over the flow range of the flow meter.

Solartron ISA’s Dualstream meters are designed for direct installation at a wellhead or flow line, either top side or subsea.

Stable and reliable with a typical lifespan greater than 20 years, Dualstream meters are ideal for unmanned platforms and marginal field development as well as for ultra deepwater installation. The Dualstream family consists of four products Dualstream Venturi, the original wet gas metering system, is a cost-effective solution for allocation or monitoring gas flow rates. Applications include tie-ins to existing infrastructure and multi-well fields, in which production fluids remain relatively constant throughout the field’s life. The Dualstream Venturi is generally used in combination with test separators or tracer dilution techniques. Dualstream 1 is a multiphase measurement solution for allocation or monitoring gas condensate wells. It is typically used on a per well basis at the wellhead or in the flow line. Standard field instrumentation makes it ideal for remote wellheads or unmanned platforms. The Dualstream 1 is recommended when real-time, high-accuracy gas measurement is a fundamental requirement, and water measurement accuracy is required for efficient well operation. Dualstream 1 replaces the need for test separators or tracer dilution techniques.

Dualstream 2 is a multiphase measurement solution typically used on wells with high levels of liquids, which can cause gas rate over read.

The Dualstream 2 uses a dual pressure differential technique to measure liquid levels and a proprietary algorithm to achieve real-time, multiphase measurement. Dualstream 3 utilizes a unique, patented Solartron approach for water fraction measurement for real-time measurement of phase fractions in wet gas applications. Its flow meters incorporate multipath, non-intrusive sensors that have demonstrated excellent performance in oil and water continuous flow and proven to be extremely robust in handling changes in field hydrocarbon compositions.

CEW INTERVIEW

“ We have emabrked around `1500 crores for the next phase of growth”

“There is significant interest across international companies who are looking at India as an alternative source to procure specialties chemicals to reduce dependency on Chinese market. With the growth of Indian economy, certain import substitutes are witnessing a good demand across end user industries, which was not the case earlier. Many such chemicals will see a positive trend in growth and I believe that we will be able to capitalize on these opportunities” says Rajendra Gogri, Chairman & Managing Director, Aarti Industries Ltd in an exclusive interview with Mittravinda Ranjan.

Where does Aarti Group stand today since the company commenced its journey?

Our journey started way back in 1975, when the Indian Government was encouraging small scale investments in chemical manufacturing to develop indigenous chemical industry for import substitution.

My brother Chandrakant Gogri – Chemical Engineer from Bombay University and his partner saw an opportunity and set up the first small scale manufacturing unit in Dombivali near Mumbai. I joined the business in 1983 after completing my Masters in Chemical Engineering from USA, and over the next couple of years, we added more small scale manufacturing units in Tarapur and later in Sarigam Though we always wanted to set up larger units, but it was only during 1990 80 • April 2017

after the end of licensing raj era that the chemical manufacturers could set up large scale facilities. In the due course we started expanding our facilities through backward integration to have feedstock security and continued to have strong focus on developing inhouse R&D capabilities which has been a strong growth driver for our organization.

Today, Aarti Group has 16 factories spread over 10 different locations where have developed diversified product portfolio of 125 specialty products through our in-house R&D which includes intermediates for dyes and pigments, agrochemicals, pharmaceuticals, rubber chemicals, home and personal care and serves over 800 valued customers in Indian as well as international markets.

How has Aarti Industries achieved strong global presence and recognised as one of the leading specialty chemicals player globally in a span of slightly over 40 years?

Chemical industry as such has a very wide number of chemicals, but from the time we commenced on our journey, we wanted to be niche in our own space and develop our own R&D capabilities. Over the years, we have built key chemistries and wide customer base that we will continue to leverage as we further expand our capacities and operations.

In-house research is on-going process for us at Aarti Industries to strengthen our technical competence and our technical teams work very closely with our customers to understand their needs and supply products to meet their specific requirements.

Chemical Engineering World

INTERVIEW CEW We have developed strong customer relationships that are based on integrity, care and excellence. In the times of crisis like product shortage etc. we have always stood by our customers and honored the contracts, which has earned us the reputation of being credible long term suppliers for our customers.

How are the market dynamics changing across various geographies and what part of production Aarti Industries exports?

Initially, it was only the dye stuff intermediates that were being exported, but as the dyeing industry moved from West of Suez to the East, the exports of dyes intermediates saw a sharp decline in exports. However, our business remained immune to the market shift since we still had the same as also new clients who had set up their facilities in India and had continued buying from us.

Moreover, there was thrust on the other sectors such as pigments, polymers, additives, agrochemicals where the developed nations started looking at India as a key supplier for products which is what gave the push in the last 10 years to our business as well.

Globally crop protection companies are very bullish as far as growth is concerned and in the years to come we are witnessing a strong demand from this sector. Worldwide, there is a strong shift from metals to innovative engineering polymers on the materials side driven strongly by the application in the space of automobiles, aerospace, electrical and electronics sectors.

We export almost fifty per cent of our total production to various countries.

North America, EU, Japan and China are the key markets for us and in terms of volume, one third of exports are for North America, one third for EU countries and then for rest of the world. China is a big market for us and accounts for almost 16 per cent of exported products. Because of the slowdown the product prices have marginally declined but since we have Chemical Engineering World

a very wide geographical spread and expansive product portfolio, we are in a pretty good shape.

In the years to come, we see a good demand for existing as well as new products across all segments from all key markets in North America, EU countries, Japan and China as well.

Though Aarti Industries has been at the forefront of being a sustainable solution provider right from the beginning, initially did you face any issues in being accepted as the preferred supplier from the global chemical majors?

No, we never faced any such issues right from the early years since we proactively engaged in following sustainable practices. While we offer niche chemistries to our customers, on the other hand we have continued to invest in improving our processes and efficiencies through our in-house research to comply with the changing regulatory standards.

We have always believed in selfregulation and one such example in this direction was to set up effluent treatment plants across all our manufacturing units out of which some have now been upgraded to zero liquid discharge.

Through our in-house research, we have developed several in-house technologies and introduced several process innovations like process to produce dry HCl to produce chlorosulfonic acid, a reactive dye intermediate. This new process offered two major advantages as it allowed us to utilise Dry HCl gas that was generated as the by product and eliminated the restriction of limiting capacity as there was no water. This technology picked up very fast since it allows the manufacturers to set up standalone plant with sulphur trioxide (SO 3 ) and there is no restriction on capacity due to lack of water content which are the major advantages of this process.

Strong thrust on innovation and R&D has been one of the key drivers for our business which has enabled us to carve our niche in the market space and become a preferred business partner for organisations of high repute not only from India but even seek strong international partnerships.

We have pioneered in introducing various technologies in India, such as commercialising Continuous Loop reactor for Eco-friendly Hydrogenation Process and become a key global player for various hydrogenated products. There are few more process innovations that we have introduced in India especially for by-product recovery and reduction of effluents and energy conservation.

We have been able to leverage on sustainability and convert it to our advantage and self-regulation has enabled us to gain the confidence of our customers. Credit also goes to the founders, accomplished technocrats with strong business acumen, who could foresee the changing market trends and nurtured the culture of research and development in the DNA of the organisation.

And now you are getting into Toluene chemistries targeted for the same users as for the benzene derivatives.

Do you see an overlap here and if this will create a challenge internally for the company?

There is no overlap here! Around 75-80 per cent of our specialty products are benzene derivatives and now we are getting into toluene chemistries, which have their own specific downstream usage. Though the products are targeted for the same end use industry it does not mean replacing the existing products but the intent is to expand product portfolio by leveraging on chemistries and customer base which will be a win-win situation for us as well as our customers.

April 2017 â&#x20AC;˘ 81

CEW INTERVIEW What are your thoughts on the Make in India campaign and its impact on the specialty chemicals industry?

Overall, it will be a very good move if the end users come and invest in India since this will create more opportunities for specialty chemical manufacturers like us.

For the manufacturers, India will be a good market since the economy is growing, but backward integration may not be a very viable option because of lower volumes since, this makes sense only when the volumes are high. For lower volumes, procurement of chemicals would make economic sense which means good business for specialty chemical manufacturers.

Just to give you an example, one of our customers backward integrated and ended up with the challenge of handling the co-product and still

had to procure product from us. However the government will need to address the challenges of infrastructure and policy related issues to create a level playing field for Indian and international players.

We have backward integrated and positioned ourselves strongly in the market which has been a strong driver for our growth and we are confident to maintain a strong growth momentum in the years to come.

What are the future plans of Aarti Industries?

Presently, we are trying to stabilize our new plants and working on products for B2B segment to supply in domestic as well as international markets. In the years to come we may get into B2C as well but that is too far at this point of time.

We have established synergistic technology partnerships with international players to

develop new product pipelines and R&D will continue to be our core focus area to understand and serve the needs of our customers.

There is significant interest across international companies who are looking at India as an alternative source to procure specialties chemicals to reduce dependency on Chinese market. With the growth of Indian economy, certain import substitutes are witnessing a good demand across end user industries, which was not the case earlier. Many such chemicals will see a positive trend in growth and I believe that we will be able to capitalize on these opportunities.

In the past we have invested around Rs. 1200 crores over the last 4 years and have earmarked around ` 1500 crores for the next phase of growth.
