CEW Industry News Chemical Industry to Touch USD 300 billion by 2025 Mumbai, India: The chemicals industry is expected more than double and touch USD 300 billion by 2025 from USD 147 billion now, according to Chemexcil. "The chemical sector is expected to double to USD 300 billion by 2025, clocking an annual growth rate of 15-20 per cent. To achieve this, government is also working on a draft chemical policy that will focus on meeting the rising demand for chemicals and reduce imports," chemicals export promotion council (Chemexcil) chairman Satish Wagh told PTI here. The industry is also targeting chemical exports of USD 18 billion by 2020 from USD 12 billion in FY17. In the first half of these fiscal, exports rose almost 27 per cent to USD 7.19 billion. The domestic chemical industry is the third largest in Asia and seventh in the world. The impact of measures initiated by government will be visible from the current financial onwards, he said. "We are unable to increase production to meet the demand. Over the past five years, there has been no capacity expansion by any of the companies because we don't get clearances from PCBs. This has dented our expor ts which provides huge oppor tunities and, of late, is also impacting domestic industries," said Wagh, adding this has led to large scale impor ts from China. Several policy measures taken by the commerce ministry in its review of mid-term foreign trade policy for 2015-20 and incentives for MSMEs in the Budget will help us in achieving our growth target, he said.

Cabinet Approves Continuation of Urea Subsidy via DBT New Delhi, India: The Cabinet on Wednesday decided to continue urea subsidy to ensure adequate quantity of the fer tiliser is available to farmers at controlled prices and to implement direct benefit transfer in the sector to reduce diversion and plug leakages. “The Cabinet Committee on Economic Affairs, chaired by Prime Minister Narendra Modi, approved the proposal of Department of Fertilisers to continue urea subsidy scheme from 2017 up to 2020 at a total estimated cost of ` 1,64,935 crore and implementation of DBT for disbursement of fertiliser subsidy,” the government said in a statement. The Department of Fertilisers is rolling out DBT in the sector nationwide. “DBT would entail 100% payment to fer tiliser companies on sale of fertilisers to farmers at subsidised rates. Therefore, continuation of urea subsidy scheme will facilitate the smooth implementation of DBT scheme,” it said. 8 • March 2018

CEW Industry News Agrochemical Sector Expects Uptick in Exports Next Fiscal

AVEVA Completes Transformational Combination as a New Software Leader is Born

Mumbai, India: The Indian agrochemical industry expects an uptick in export revenue next fiscal after suffering slowdown in two successive fiscals caused by lower usage of agrochemicals by farmers in key export markets like Latin America on the back of unremunerated prices for agri produce.

Mumbai, India: AVEVA has combined with Schneider Electric’s industrial software business to drive digital transformation across the asset and operational life cycle for capital-intensive industries. This unmatched, end-to-end offering unlocks the power of two industry leaders to deliver improved profitability and operational excellence to maximise return on capital.

Latin American nations, which account for large exports from Indian agrochemical firms, reported a fall in growth rate to 4% against 10% growth repor ted earlier. This has led to higher inventory levels of agrochemicals in those markets. With agro-commodity prices looking up in Latin American markets, coupled with fall in exports from China, sectoral analysts now expect a growth of 10-14% in export revenues for Indian agrochemical sector next fiscal. Further, new product launches could help in improved business volumes. India is the fourth largest global producer of agrochemicals after the US, Japan and China with an industry size of around $4.9 billion in FY17 with exports accounting for nearly half of it, says rating agency Icra. Latin American markets, which account for nearly a third of Indian agrochemical exports, suffered slowdown in both the last fiscal and ongoing fiscal, said Rahul Veera, assistant vice-president, Elara Capital. This, he said, was mainly due to low agro-commodity prices arising out of a deflationary trend in the global markets.

B l a ck & Ve a t ch N a m e d L N G I n d u s t r y E P C Contractor of the Year Mumbai, India: Black & Veatch, a global leader in the design, construction and delivery of innovative floating liquefied natural gas (FLNG) production and regasification solutions, has been named EPC Contractor of the Year. The award, presented to Black & Veatch at the recent LNG USA Summit 2018 in Houston, cited the company’s advanced capabilities in executing complex projects and coincides with increasing investor interest in flexible, cost-effective LNG solutions that can more quickly move supply to end users. “Being named EPC Contractor of the Year at the LNG USA Summit demonstrates our commitment to helping clients meet their objectives, regardless of project size, by being the top EPC solutions provider for FLNG developments,” said Bob Germander, Senior Vice President and Managing Director of Floating Oil & Gas Solutions for Black & Veatch. “This honour at the LNG USA Summit recognizes the core strengths behind Black & Veatch’s leadership position in the natural gas marketplace. Our innovative solutions combined with efficient, cost-effective and on-time EPC capabilities make us a one-stop solution for clients,” said Javid Talib, Vice President and Director of Floating Technology Applications for Black & Veatch’s Oil & Gas business. 10 • March 2018

The combination brings together AVEVA’s design, engineering and construction capabilities with Schneider Electric’s industrial software business, which ranges from simulation through to real-time manufacturing operations management. It creates a global leader in engineering and industrial software, expanding the markets and industries the company serves. Customers can benefit from improved profitability, efficiency and performance. “The combination of AVEVA and Schneider Electric’s industrial software business brings together CAPEX and OPEX, creating a path to digitalisation from conceptual design to commissioning, and from operations back to revamps. Many industrial businesses already use software from both companies and look forward to the benefits of having these products under one developer umbrella. Adding in real-time production performance moves the industry one step closer to realising a digital asset that operates with full knowledge of its physical layout as well as the underlying physics of the process being conducted. I’m excited to see how AVEVA integrates processes, products and people.”

Coyotex to Showcase its Pioneering Technology for the Production of Multiaxial Carbon Fiber Preforms Überlingen, Germany: Coyotex is revolutionizing the production of carbon fiber composites: Thanks to this newly developed production process, the company’s customers can reduce their expenses by up to 40 percent. Coyotex can manufacture multiaxial preforms with significantly higher lightweight potential on an industrial scale. Ordering the products is completely digitalized, and production takes place on demand. The first-ever public presentation of this technology will be held at the JEC composites trade show in Paris (March 6-8). Coyotex has also been nominated in Paris for the Startup Booster award, which recognizes innovative solutions in the composites field. “Our new technology will fundamentally change the production of carbon fiber composites,” says Rainer Kehrle, Managing Director of kejora GmbH, which owns the Coyotex brand. Although the company’s idea isn’t new in itself, the results definitely are: Until now, producing non-crimp fabrics (NCFs) in near net shape has involved high production and equipment costs as well as modest output. In contrast, fast production processes come at the expense of lightweight potential and lead to significantly higher costs further on in the process chain. Chemical Engineering World

Cooling System and Petrochemical Industry Petrochemical industries generate large quantities of waste heat. Therefore, cooling system considerations constitute an important aspect of petrochemical development schemes. Technically feasible and economically favorable industrial cooling solutions are essential. To best optimize the efficiency of a cooling system, a “systems approach” should be used to identify potential savings and performance enhancement. This approach looks at the entire cooling system, including the pumps, motors, fans, nozzles, fill, drift losses, evaporative losses, blow down, makeup rate, chemicals, flow rates, temperatures, pressure drop, as well as operating and maintenance practices. By focusing on the whole system as opposed to just individual components, the system can be configured to avoid inefficiencies and energy losses. Cooling systems do not operate under one condition all the time and system loads vary according to cyclical demands, environmental conditions, and changes in process requirements.

ooling systems are either “Oncethrough” or “Recirculating”. A Oncethrough system uses the cooling water only once before it is discharged. A Recirculating system recycles the cooling water after it has been cooled at a heat sink. Cooling systems are also classified as “Closed” or “Open”.

Once Through: Coolant passes through heat exchanger once before returning to its source. • River/lake/ocean/sea to process and return back to source.

Open Systems: Process medium is in contact with the environment. Only applied to a wet system but may be a once through or recirculated design. • Forced and natural draft cooling towers, cross flow towers (water/air)

• Sensitive to fouling, scale, corrosion, and fish intake. Uses large amount of water and risks putting additives into water source.

• Cooling ponds use evaporation to discharge heat, prior to reuse in the process. • Some systems such as a wet surface air cooler combine open and closed design Closed Systems: Process media is inside tubes or heat exchanger and is not in contact with the environment. May be a wet or dry system and may be a once through or recirculated design1. • Heat exchangers of the shell & tube or plate & frame type. • Tubed fan cooler - fluid in tubes, air blowing over the tubes for cooling. Once through or recirculated design. Designates whether the primary coolant is returned to its original source or returned to the process for reuse. A direct cooling system may contain one of these design features whereas an indirect system may contain both. 14 • March 2018

• This is the easiest and most efficient system to use although high discharge temperatures must fall within permissible limits.

Recirculated: Primary coolant is reused whereby heat is absorbed in one exchanger and then transferred to a second coolant in secondary exchanger. • Eliminates environmental impacts to water supply. Direct or indirect systems, also known as primary and secondary systems. This term indicates where the primary process media is discharging heat directly to the environment or to a secondary media. Direct: System with one heat exchanger or cooling tower, and only the process media and a coolant. Indirect: There are at least two heat exchangers, and a closed secondary coolant between the process media and the primary coolant. Indirect cooling systems are applied where leakage of process substances into the environment must be strictly avoided. • Efficiency is not as high as direct due to extra heat exchanger stage.

• Common in nuclear plants or with hazardous chemicals. Wet or dry cooling system, refers to whether or not cooling water or ambient air is used as primary cooling media. Dry: Uses forced air over tubing with fluid process media. • Only applied to closed systems. • Typical in areas without cooling water source available. • Tubed fan coils Fin/fan coolers – fluid in tubes, air blowing over the tubes for cooling. Wet: Involves either the use of the process fluid being cooled with air in an open cooling tower, or being cooled by water in a closed heat exchanger. • Cooling towers – Evaporative heat transfer. Include cross-flow cooling towers, hyperbolic towers. The fluid to be cooled is in contact with cooling air flow and there are some evaporative losses. • Shell and tube or plate and frame heat exchangers. The type of cooling system chosen may also reduce or eliminate environmental impacts. An air/water cooling tower may be used instead of a once through cooling system to minimize water usage or thermal water pollution. The air and water permits will generally specify certain design features such as the type of cooling system, maximum permissible withdrawal volume & discharge temperature for once through Chemical Engineering World

CEW Features systems, cooling tower drift rate, and other permits may specify water consumptive use, cooling water discharge temperature, noise levels, etc. Application of Technology Efficiency gains are available with each cooling system design. New systems have the most potential for optimization using the latest technology, although existing systems have potential as well but will generally be limited by layout and construction issues. The type of cooling system selected requires extensive evaluation at the design stage of a project using many design inputs including costs, layout and size, water availability, energy consumption, energy efficiency, ambient conditions, seasons and weather, and many others depending on the project. Annual variations in local water and air temperatures have the largest influence on the efficiency of the cooling system. System efficiency is a function of the costs of the energy and resource input needed to operate the system vs the amount of cooling achieved. Electricity is used to operate fans and pumps, and other costs incurred include make up water costs as well as regulatory costs and penalties. Cooling Towers – Wet evaporative systems are limited by the wet bulb air temperature and dry systems are limited by the dry bulb air temperature both which fluctuate throughout the year. These limitations may cause a plant to run at reduced capacity or run at lower cooling efficiency. Cooling capacity may be increased by adding additional cooling cells or by correcting design sizing errors. Fans and Pumps – Fans, blowers, and pumps may be idled or slowed during times of favorable weather conditions or low plant load to reduce energy consumption Variable Speed Drives (VSDs; also called Adjustable Speed Drives, or ASDs) are commonly used on fan, blower and pump motors because they greatly improve cooling system energy efficiency at partial loads, relative to continual operation. Automation – Modern controls offer ways to improve efficiency by continuous monitoring of key system parameters with automated adjustments to pumps and fans. 16 • March 2018

Cooling Medium Temperature – The efficiency of cooling systems depends on the temperature of the medium to which the heat is being expelled. Cooler mediums are easier to transfer heat to, so less cooling medium flow is necessary, reducing pumping/blowing energy demands. In many cases, the temperature of water sources is lower than the surrounding air temperature, so using water-based cooling systems can be more energy efficient. Exchanger Approach Temperature – The temperature difference between the cooled working fluid (as it leaves the cooler) and the incoming cooling medium is called the approach temperature. It is important for designers to not specify approach temperatures any smaller than required, as smaller approach temperatures require greater cooling capacity (e.g. larger cooling equipment, higher flow rates). Offshore Cooling Systems – Cooling systems on offshore facilities often use seawater as the cooling medium, given its plentiful availability and low, steady temperature. Such systems, however, must resist corrosion from this salt water. Operational Issues/ Risks Cooling systems require regular cleaning, maintenance, and scheduled overhauls to operate at high efficiency. This can range from simple preventative maintenance activities (i.e. flushing) to repairs that require the tube bundle to be removed from the heat exchanger shell for cleaning or even replacing entire cooling towers. This down time should also be taken into consideration when sizing the heat exchangers.

can disrupt operations if not properly handled. Cooling towers are used to cool this process water for reuse. The towers must be able to handle the heat load as well as any problems unique to the industry. Leaks in the process can cause hydrocarbons to contaminate the cooling water and vice versa. Lower quality, no potable water often is used to cool plant processes. Meeting environmental regulations limiting hydrocarbons, water usage and drift rates present challenges to plant operators. New industry regulations often require cooling towers to lower the drift rate to 0.0005 percent of circulating water flow, which can be difficult to achieve in older evaporative cooling towers. Many cooling towers currently in use are not equipped to handle these demands. A few decades ago, field-erected towers commonly used wood structural members. These cooling towers are coming to the end of their service lives, experiencing mechanical failures, requiring unplanned maintenance that interferes with production and impacting facility productivity. The heat transfer fill in the towers also degrades over time, getting plugged with waste from dirty cooling water and breaking down from the weight of debris.

Thermal Design Aspects of Shell and Tube Type Heat Exchanger Heat transfer is the most important and applied operation in chemical and allied industries. Economy and Energy of plant operations are controlled by effective utilization of heat energy. From the viewpoint of engineering, an optimum design is obtained via maximum heat transfer rate at minimum cost. Shell and tube type is the most dominant type of heat exchanger in process plants today and in many cases it is the best or only option. On the other hand, too often shell-and tubes are selected almost “by default” because of familiar technology. The design procedure depends on using the acceptable pressure drops in order to minimize the thermal surface area for a certain service, involving discrete decision variables. Designers need to consider some additional aspects such as geometrical features and velocity conditions for an efficient design. The optimization algorithm is based on an exploration of different factors involved including the tube count where the established constraints and the investigated designers are employed to eliminate non optimal alternatives, thus the number of rating run simulations executed get reduced which also stands for time management.

hell and tube heat exchangers (STHE) are important components in energy conversion systems in oil, Refinery, Petrochemical and chemical industries. In these industries, the heat transfer rate and the total cost of the shell and tube exchangers significantly affect system designs. Due to their compact design, these heat exchangers contain a large amount of heat transfer area and also provide a high degree of heat transfer efficiency. A good working knowledge of the mechanical features of STHEs and their influence in thermal design serves as an effective tool for the designer. The principal components of an STHE are shell, shell cover, tubes, channel, channel cover, tube sheet, baffles and nozzles including some other components include tie-rods and spacers, pass partition plates, impingement plate, longitudinal baffle, sealing strips, supports, and foundation. For designing of any STHE, critical information like flow rates of both the streams, operating pressures, inlet and outlet temperatures, allowable pressure drops, heat duty, line size, etc. has to be collected from the process licensor. Additional factors like fouling resistance, physical properties of the fluids, and material of construction are 18 • March 2018

required before designing the exchanger. Further, specific instructions given in the project specifications are also considered as inputs. Although thermal design of STHE is done by sophisticated simulation software, a good understanding of the underlying principles of exchanger design, STHE classification, tube layout, exchanger components, etc. is needed to reach at an optimal design. TEMA Selection & Main Thermal Design Aspects The TEMA (Tubular Exchanger Manufactures Association) Standards recognize three classes of heat exchanger construction. Class R: for the severe requirements of petroleum processing (and usually including most large scale processing applications). Class C: for general commercial application. Class B: for chemical process service. Based on the end connection and shell type, the STHE are classified using three letter codes; the first letter indicating the front-end head type, the second the shell type, and the third the rear-end head type.

Know Your Heat Duty: The duty specified should be consistent for both the shell side and the tube side. The heat duty is calculated by the formula: Q= U D Ao Δ Tm where, U D= Required Overall heat transfer coefficient. Ao = Effective heat transfer surface based on tube outside area. ΔΔTm= Effective mean temperature difference. Next step is to determine U actual based on shell side and tube side film coefficient. For optimal geometry U actual should be greater than U required. Generally Heat Exchangers are over designed and the amount of over design is arrived at using the following formula: (U actual – Urequired) % Over design = ------------------- X 100 (U required) For an optimal design the overdesign is maintained around 10-15%, unless there is a specific requirement from the process licensor.

CEW Features Fluid Allocation and Pressure Drop Calculation: The fluid allocation for a heat exchanger is often governed by requirements which have implications on the safety, cost, and ease of maintenance of the heat exchanger. Generally highly viscous fluids having low heat transfer rate are passed through the shell side and dirty, corrosive fluids which contain non condensable gases & solids are passed through the tube side.

Corrosion Allowance: Corrosion allowances are required for the various heat exchanger components to allow for the material loss due to corrosion in service. Corrosion allowances are specified according to the severity of corrosion and the corrosion resistance property of the material. Film Co-efficient: The heat transfer coefficient of tube side and shell side fluid is very important and the individual heat transfer coefficients must be high enough to attain high overall heat transfer coefficient. The individual film coefficients of Shell side and Tube side fluid are taken from simulator output sheet. Mean Metal Temperature: The determination of the mean metal temperatures should be based on the operating temperatures of both the shell side and tube side fluids with due consideration given to such factors as the relative heat transfer coefficients of both fluids , the relative heat transfer area of parts in contact with both fluids, etc.

Tube Passes: The number of tube passes will be optimized from a single pass, 2, 4, 6, 8, 10, 12, 14 and 16 passes. Increasing the number of passes in tube side, increases tube side velocity which will give high heat transfer coefficients and a higher pressure drop. Tube Length: Tube length may be used for both straight and U tubes are 2438 mm, 3048 mm, 3658 mm, 4877mm, and 6096 mm. The optimum tube length to shell diameter will usually fall within the range of 5 to 10.For U-tubes the length shall be taken as the straight length from end of tube to bend tangent. Effective tube length mainly indicates the tube length to be used to calculate the heat transfer surface area but also will be used to tube side pressure drop or baffle spacing calculation. Shell: Up to about 24” (610 mm) shells are normally constructed from standard, close tolerance, pipe; above 24” (610 mm) they are rolled from plate. The shell diameter are commonly used is 8”, 10”, 12”, 16”…….60”. Baffle: Baffles must generally be employed on the shell-side to support the 22 • March 2018

tubes, to maintain the tube spacing, and to direct the shell-side fluid across or along the tube bundle in a specified manner. Baffle cut is the segment opening height expressed as a percentage of the shell inside diameter or as a percentage of the total net free area inside the shell. The types of baffles are – •

Segmental Baffle: Simple and most frequently used and is strongly recommended when baffle cuts between 20 to 35 % is employed. Baffle cuts are Horizontal cut (Perpendicular cut) which is used mostly in single phase & Vertical cut (Parallel cut) mostly used in condensers.

•

Double Segmental Baffle: For the same total flow rate of the shell side fluid, double segmental baffles give the pressure drop of 1/3 of the segmental baffles having the same spacing and cut.

•

Impingement Baffle: Inlet impingement plates are used to prevent the incoming fluid from directly impinging upon the tube bundle. An impingement plate should be provided depending on the value of ρV2 of the incoming fluid.

Baffle Spacing Baffle spacing is the center line-to-center line distance between adjacent baffles. Total baffle and support spacing is equal to the effective tube length (Le). Segmental baffles normally should not be spaced closer than 1/5 of the shell inside diameter, or 2” (50 mm), whichever is greater. Vibration Analysis Selected values on the vibration report of simulator appear with an asterisk (*).These values exceed lower safe limits. Following steps need to be followed to reduce these.

Conclusion On the basis of above study it is clear that a lot of factors need to be considered for optimized designing of a SHTE which can affect the performance of the heat exchanger. During optimization it must be noted that the advantage in one of the output parameter can affect the other parameters, which can lead to increase in initial or operating cost. These days since the end users are expecting more cost competitive and schedule driven projects, detailed engineering consultants are expected to correctly and completely specify all the technical requirements/details in the requisite document to avoid changes at a later stage which may results in project cost and time over-run.

Process Monitoring Solutions for Boiler-Feed and Cooling Water Streams in Power Plants Nearly 50 per cent of unplanned downtime in power plants is caused due to contaminants or problems in the chemistry of the water-steam circuit, with corrosion being the primary factor. Every cooling circuit has a unique design and thus its own unique challenges. The specifics of the water che-mistry to be regulated (and therefore the applicable limits) depend on the type of power plant, the cooling circuit design, and construction materials. Timely and effective monitoring of power plant water chemistry is critical for maintaining efficiency and safety. By using online analyzers, operators gain the information they need to accurately identify trends and address operational issues before costly problems arise. In this review, we highlight the importance of such real-time analyzers in boiler-feed and cooling water streams to optimize safety and plant efficiency.

he rapid increase in the Earth’s population, which is growing by about 80 million every year, has also led to rising energy consumption. Calculations by the International Energy Agency (IEA) predict that the global energy demand will increase by about 65% by 2035. A major fraction of the required energy will continue to be provided by fossil fuel-fired and nuclear power plants. Various guidelines define the permissible operating ranges for water chemistry used by power plant operators, including standards provided by the Electric Power Research Institute (EPRI), the Association of Large Boiler Operators (formally known as VGB – Vereinigung der Grosskesselbesitzer e.V.), the European Power Plant Suppliers’ Association (EPPSA), and the International Association for the Properties of Water and Steam (IAPWS). Nuclear power generation is governed by the safety standards of the Nuclear Regulatory Commission (NRC) and the International Atomic Energy Agency (IAEA).

for most chemistry-related damage and efficiency loss are now very well understood, but the precise conditions at which corrosion and deposition activity begin are still not known. Past and present chemistry guidelines all serve to provide the operator with a warning as to when corrosion and/or deposition activities that place the power generation unit at risk may begin. Flow-accelerated corrosion (FAC) of the metal components in power plant watersteam circuits reduces the lifetime of water-exposed carbon steel pipework and copper heat exchangers. Zinc ions, phosphates, and phosphonates are commonly used as corrosion inhibitors in steel piping. Chloride causes pitting

corrosion on turbine blades and rotors. In combination with sulfate, it also leads to corrosion fatigue and stress corrosion cracking (SCC). Water Circuits in Thermal Power Plants Thermal power plants use the heat generated by combustion or nuclear fission to produce steam, which is fed into a turbine driving a generator that converts the mechanical energy into electrical energy. Downstream of the turbine, the steam is condensed to water in a condenser. This water is fed into a feed tank from where it is pumped back into the steam boiler. Cooling water flows through the condenser in a separate circuit and removes the heat of

CEW Features Not only do dedicated online analyzers help to safeguard plant operation and efficiency, but they also provide a continuous record of plant operating conditions for increased plant uptime and to facilitate long-term improvements in productivity. A strong requirement for integrated online analytical systems based on lab-proven methods in titration, spectroscopy, electrochemistry, photometry, TOC, ion chromatography, and ion selective measurements is clearly visible that contribute towards a reliable and sustainable operation of power plants to minimize costly downtimes. Nuclear Power Plants

condensation released by the steam via a heat exchanger. Nuclear power plants with pressurized water reactors have an additional water circuit known as the primary circuit. All thermal power plants use water as a central (operating) medium. As a liquid, it is used for cooling and as a gas, it drives the turbines. In nuclear power plants, it also moderates the fission neutrons and thus controls nuclear fission. A welldevised water chemistry ensures safe and efficient power plant operation. The water chemistry depends on the type of power plant, the cooling circuit design, and the construction materials. Dedicated Online Analyzers Effective cycle chemistry programs depend upon the selection of treatments customized to the specific unit and its characteristics. Treatment control and optimization, in turn, requires rapid, accurate sampling and analytical capabilities. While all power plants can benefit from online analysis of critical parameters such as corrosion indicators and inhibitors for optimum chemistry control, monitoring of diagnostic parameters such as chloride, sodium, sulfate, ammonia, hydrazine, silica and TOC can also be highly advantageous for protection and process optimization. 28 â&#x20AC;˘ March 2018

The most common types of nuclear reactors are the boiling water reactor (BWR) and the pressurized water reactor (PWR). The primary circuit of a PWR circulates cooling water at high pressure (up to 160 bar) through the reactor core, where boric acid dissolved in the primary circuit acts as a moderator for the nuclear reaction. Determination of boric acid concentration in the primary circuit is thus extremely important in controlling reactivity for reactor efficiency and safety. Fuel assemblies cannot be exchanged during operation of a PWR due to their use of light water, so a fuel reserve must be in place prior to the start of an operating cycle. The associated excess activity in the reactor is controlled by using a higher boric acid concentration.

Process Based Analysis of Boric Acid The Boric Acid Process Analyzer provides fast and reliable values via potentiometric titration for continuous monitoring of boric acid concentration throughout the fuel cycle, both during the process and in the spent fuel pool. Efficient use of an automated titration system eliminates the tedious pipetting of the sample, distilled water, and mannitol solution needed for boric acid determination through manual methods. Automated analysis improves accuracy, eliminates the potential for operator

error, and provides more rapid process feedback to maximize operational efficiency.

Fossil Power Plants Fossil power plants consume fuel such as coal, natural gas, or oil, generating electricity via a steam turbine. The steam generation process requires cooling water, either in a closed loop or open loop system, so that the steam can be condensed for either re-use or discharge depending on the type of system. Cooling water composition must be monitored to optimize power generation, ensuring plant efficiency and safety.

Cooling Water Cycle Cooling water is used to condense the exhaust steam from the turbine to water, traveling through kilometres of piping in the condenser before being sent back to the water-steam circuit as feed water. The cooling water itself is cooled either by once-through cooling, in which heat is transferred to water taken from a river or in a circuit in a wet cooling tower via heat dissipation into the atmosphere. Continuous circulation of the cooling water in either system increases the concentration of contaminants, and requires water analysis to control corrosion and deposition processes taking place in the cooling water circuit. Thus, cooling water composition must be monitored to optimize power generation, ensuring plant efficiency and safety.

In-line Monitoring of Silica Build-up of silica from boiler feed and cooling water can lead to reduced boiler efficiency and eventually blockage and rupture of pipes. Monitoring of the silica content in influent and cooling water can provide valuable information that is useful in preventing scaling and operational efficiency losses. A single parameter silica analyzer can monitor silica levels from low ppb to high ppm level, which Chemical Engineering World

CEW Features is critical for maintaining the required low levels of silica and preventing costly scaling and related issues.

In-line Monitoring of Phosphate Trisodium phosphate is used for corrosion prevention in boiler water systems, leading to the need to monitor phosphate levels at several points within the process. Phosphate levels are ideally kept low to prevent any precipitation and solids transport, yet must remain high enough for corrosion prevention. The phosphate used for this purpose can sometimes be carried over into other systems, particularly the steam system, leading to similar precipitation and scaling issues and thus a real-time analyzer proves to be a highly efficient solution.

In-line Nitrogen Species Analyzer Ammonia is added to cooling water streams to help maintain a slightly basic pH, thus slowing corrosion. Other nitrogen containing corrosion inhibitors such as azoles are sometimes used, which can degrade to produce nitrogen species such as ammonia, nitrite, and nitrate in water streams. A Nitrogen Species Analyzer delivers rapid, accurate measurements of ammonia, nitrite, and nitrate species simultaneously, and can be configured to handle multiple streams. Conclusion Compared to an expensive yet bench top based ICP-OES or GC-MS systems,

such real-time based process analyzers are cost-effective and efficient solutions to a variety of process analytical needs in power-plants. Not only are they capable of providing ‘real’ data for control parameters, they can alzso be recognized as the future guiding platforms for overall process sustainabilit.,

Water Level Gauges for Process Control in the Steam Power Industry Water level gauges or indicators are devices that measure, display and transmit, water level continuously. This article discusses the role water level gauges/indicators can play in monitoring the process and ensuring security, reliability, efficiency, and economy.

Why water level gauges are essential? During the entire operation of a boiler, a low water level condition in the boiler drum can damage the boiler tubes. On the other hand, a high water level can damage the steam separator or steam turbine due to carry over of water. The American Society of Mechanical Engineers (ASME) regards the water level in the boiler/steam drum as a crucial plant parameter. For coal/oil-fired boilers, the ASME code recommends minimum one water level visual gauge to provide a definite value of the steam drum water level.

mandatory to detect the presence of water in the interior or the exterior of the turbine prior to any damage that can occur.

In feedwater heaters, visual water level gauges, magnetic level indicators and transmitters, and high/low-level switches are used to determine the water level.

Specifics of the water level gauges

Design of the water level gauges

Water level gauges can be used for measurement up to 600 degrees Celsius temperature and 200 kg/cm 2 pressure.

While designing a power boiler steam drum visual water level gauge, the following points must be noted: • The pipes used for connection purpose must be minimum one inch in diameter to allow quick and free flow of water into and out of the level gauge.

In case of feedwater heaters, a low condensate level results in the steam being discharged directly to the next heater. This minimizes the efficiency of the feedwater heater. Likewise, a high condensate level results in the opening of the steam safety valve. In this state, the feedwater heater does not function at optimum efficiency. Thus, it is of significance that the low or the high water levels in the feedwater heater steam section must be monitored. Here too, the water level gauge comes in handy.

Water level gauges used with boilers must have minimum one gauge glass. This is transparent and facilitates to visually record the water level. To differentiate between the water level and the steam level, end-connected strip gauges or ported gauges, with bi-color indication facility are used. In a bi-color gauge glass, water portion is indicated by green/blue light and steam portion is indicated by means of red light. If the maximum permissible working pressure of the boiler is more than 28 kg/cm 2 , two disparate water level gauges or gauge glasses should be in use. If two water level gauges are in use, the one gauge glass can be maintained in usable condition and the other may be shut off during operation.

In case of steam turbines, each connection to a turbine is a potential water source, which may allow entry of water into turbine. It can be by means of collection of condensed steam or induction from external equipment. At times, the water source causes serious damage to steam turbine, which leads to reliability, security, and fiscal concerns. It is here that a water level gauge is

It may happen that the gauge glass cannot be easily seen by the boiler operator. In such a case, the optical image of the water level must be transferred to the control area by means of mirrors or a fiber optic cable. An alternative solution is to install an independent water level gauge or arrange for perpetual transmission and display of the water level in the gauge glass by means of CCTV.

Chemical Engineering World

• The minimum water column drain size must be 0.75 inches in diameter. • To avoid stoppage of water by sediment deposits, ‘Through Flow’ valves that indicate the open or the closed position must be chosen. At times, double block valves are essential. • A water column should be included to minimize the amount of condensate flowing through the gauge. If the condensate quantity is excess, the water level reading becomes difficult to read and also the reading is unstable. • For high-pressure boilers, the optimum design is of ‘Ported Bi-color’ gauges. • The inclusion of gauge isolation valves is useful in case of gauge failures for isolation of the gauge from a secure lower level. These valves are frequently used with chainwheel operators. March 2018 • 31

Procurement Transformation Roadmap Any manufacturing company needs to be masters at purchasing raw materials in order to produce their end products. This article intends to fathom the current state of procurement system and transformation reshaping every aspect of this field.

s your department called Purchasing,

•

Buyers are asked to get minimum three bids and go with the lowest

• Spend analysis,

•

Buyers take care of ordering materials and dealing with faulty materials

• Supplier evaluation/selection relationship management.

•

High number of suppliers means security

The typical characteristics of a Sourcing Department are:

•

Specifications are sent to the department to order the goods/ services

• The Procurement Department adds value to the bottom line of the company

•

Internal stakeholders always complain about the department

•

Maverick buying is quite common

• Terms like TCO, SLA, Risks, Hedging, SPM, Sustainability, or Supplier Collaboration are embedded in the day to day activities of the buyers

•

Purchase office always in fire fighting mode.

• The Procurement Manager reports to the CEO

Buying, Sourcing or Procurement?

Even if the definitions of the different terms seems quite similar, the name of the department can establish how important is the function within the organization and what level of maturity it has accomplished. Both sourcing and purchasing/buying can be considered a subset of Procurement. Tactical purchasing is simply executing routine tasks – receiving purchase requisitions, requesting quotes/RFP, placing orders, expediting, etc. on a repetitive basis, outside of the context of an enterprise-wide focus, and without pursuing continuous improvement or contribution to specific senior management goals. The Procurement function has developed considerably over the last several years, and is evolving daily. Most organizations start with a tactical Purchasing Department, which has to deal with all the administrative tasks associated with onboarding of suppliers and ordering. The typical characteristics of a tactical Purchasing Department are: •

Purchasing Department is a cost center

•

Price is the main decision factor and “negotiation cum squeezing” the suppliers for the lowest price a normal practice

Chemical Engineering World

Over time the department develops by adding the sourcing part, introducing new tools, processes and targets, and maximizing the control over the spend of the company. Strategic sourcing is a systematic, long term and holistic approach to acquiring current & future needs of an organization at the lowest total cost of ownership (TCO) and lowest risk to the supply line. This process creates a closed loop link between customer and the supplier to ensure continuous improvement in quality, delivery, cost and service while providing the means to achieve optimal efficiencies in both (customer & supplier) organizations. There are three very important components of strategic sourcing

Automated Device Commissioning with Intelligent Commissioning Wizard The new Intelligent Commissioning Wizard from Schneider Electric enables device commissioning in a single step by completely automating detection, configuration, commissioning and testing of HART field instrumentation connected to a Foxboro DCS. This articlediscusses limitations of the traditional methodology of configuration and commissioning of field devices and technologies that minimizes the duration of the process and minimizes error, which in turn reduces the risk of delays, improving business performance.

anufacturers face ever-increasing demand to speed up execution of megaprojects and shorten the period of plant shutdown, getting back into production as quickly as possible, so as to maximize operating efficiency in a fragile and rapidly changing economy. Larger projects mean larger & more complex automation systems configuration, commissioning of which constitute one of last but critical tasks performed before plant startup. Current practice for configuration and commissioning of automation systems including field devices is not only tedious and timeconsuming but also error prone. End users are now searching for new technologies and processes to eliminate, simplify and/ or automate steps in overall commissioning to minimizing cost, complexity & risk to the project. It is critical to the success of the project to implement solutions that save time, reduce risk and increase accuracy. The new Intelligent Commissioning Wizard from Schneider Electric enables device commissioning in a single step by completely automating detection, configuration, commissioning and testing of HART field instrumentation connected to a Foxboro DCS. Limitations with Traditional Methodology of Configuration and Commissioning Over the years, process automation projects are becoming increasingly complex and technologically demanding especially in large asset intensive industries — like mining, oil and gas, energy, utilities etc. The duration of project execution and risk Chemical Engineering World

of these megaprojects is becoming critical to the profitability of these companies. If executed successfully, these projects enhance shareholders’ value; poor execution can potentially impact the companies’ performance, significantly putting the organization’s profitability and shareholders’ value at risk. Recently, Booz Allen Hamilton, a strategy, technology, and engineering consulting firm with more than 100 years history did a survey with leaders from 20 companies—including supermajors, independents, and EPC firms, as well as some heavy industry companies from the United States, Europe, and Asia. More than half of the executives surveyed were dissatisfied with their companies’ overall project execution performance, citing high cost and schedule overruns that plague 40 per cent of their projects. A 2014 report by EY (formerly ERNST & YOUNG) one top 4 professional business consulting & management consulting firms reveals that almost two thirds (64%) of multibillion-dollar megaprojects continue to exceed budgets, with three quarters (73%) missing project schedule deadlines. As process industry projects becomes larger and larger, the resulting complexity of the automation systems also increase exponentially. Plant automation systems and field devices are not only fundamental building block of any asset intensive plant, but also represents significant capital and operational cost. Commissioning and configuration of field instruments and valves are the final but critical tasks on the critical path to plant start-up and the impact on

overall project schedule and performance is significant. While field instrumentation technology has made significant advances, device configuration and commissioning has remained largely manual and this does not help with the increase in the amount of data and parameters that field devices measures. Some of constrains associated with traditional method of device commissioning includes: • Manpower Intensive: Traditional commissioning and configuration methodologies are cumbersome, time consuming and labor Intensive. The time required to configure and commission can range from as little as 15 minutes for low-complexity devices like pressure transmitters to more than 50 minutes for more complex assets like flow meters etc. Testing and report generation adds even more hours to the process • Error Prone: The risk of user error during manual commissioning and configuration is huge. It is easy to make typing errors during manual entry of device data and setting of operational parameters. The technician may miss configuring a new device in the network or forgot to put the device back into operation after service • Expertise Dependence: Safe and reliable operation of control system is dependent on the field instruments and valves. This highly relies on the expertise of the technicians assigned. March 2018 • 35

CEW Features Taking into consideration constraints associated with traditional methods of configuring and commissioning of instruments and valves, business owners are looking for ways to simplify and/or automate the activity. In recent times, manufacturers are gravitating towards working with their instrument vendors to pre-configure devices before it is delivered to site. But the premise that faster commissioning can be achieved by “finetuning” the traditional approach is a fallacy and will only result in marginal improvements. The industry must make a paradigm shift by eliminating manual configuration, commissioning and testing altogether. The entire device commissioning process starting from device detection to configuration to commissioning, loop testing and reporting needs to be completely automated. Intelligent Commissioning Wizard - A Paradigm Shift in Hart Device Commissioning The new Intelligent Commissioning Wizard embedded in the EcoStruxure Field Device Expert is a technology-enabled approach to commissioning of HART field instrumentation of any make and version connected to the EcoStruxure Foxboro DCS. It enables commissioning of HART Devices in a single step by completely automating detection, configuration, commissioning, and testing. The Intelligent Commissioning Wizard even creates commissioning reports upon completion which further shortens the duration of the commissioning process. Two Use Cases Depening Upon Type Of Marshalling Cabinet Intelligent Commission Wizard supports both Traditional & intelligent marshalling approach With Traditional Marshalling Cabinets Testing and report creation represent significant time & cost in the project scope.

and commissioning duration. Intelligent Commissioning Wizard has the capability to verify the I/O card type and card channel assigned during the engineering phase vs what is built into system cabinets, cross wiring in the marshalling cabinets, field cables and field junction boxes. A Verification Report is automatically generated upon completion. With Intelligent Marshalling Cabinets Schneider Electric’s Intelligent Field I/O Cabinets (Pre-fabricated marshalling cabinets with Intelligent I/Os) for both Process and Safety, together with Intelligent Commission Wizard and Schneider Electric’s FLEX (Flexible, Lean EXecution) project execution methodology has dramatically changed the way automation projects are executed. System Configuration at the Project Office As soon as the initial P&ID designs are available, the project team located anywhere in the world can start building control loops without I/O assignments and without configuring HART devices in the system until the hardware is delivered to site. The Intelligent Commission Wizard enables late binding where I/O references are not defined until the field devices are installed and commissioned on site. This decouples hardware and software design freeze, reduces risk and provides greater flexibility in the project, taking automation off the critical path. Optimized Site Activities While the system configuration is being done at the project office, the field team can start field cable installation & termination simultaneously

• Automatic Loop Test • Automatic Report creation Commissioning and configuration of new devices have long been a time consuming, tedious, task when conducted manually. While configuration, commissioning, testing of low-complexity devices might take as little as 15 minutes, the more-complex assets can take more than an hour or more. Testing and reporting further add to the duration of the task. •

•

Automatic Binding and Configuration of HART devices Based on test done using automatic binding and configuration of HART devices, commissioning schedule has been demonstrated to be reduced by more than 70%majority of instrumentation like transmitters Automatic Loop Tests Loop Tests has traditionally been done using two technicians; one in the field to simulate an analog value at the transmitter and the other at the automation system to check the corresponding value displayed in graphics and faceplates. Automatic Loop Tests completely automates the process and reduces the manpower requirement to one instead of two. Automatic Report Generation The automated process delivers more than 70% savings in time and effort per device, and at the same time reduces errors and minimizes the risk of schedule overrun. Applying these savings across hundreds and thousands of devices required to get a new facility or an expansion up and running, the choice is apparent.

The name Diphyl denotes a family of products produced by mixing diphenyl oxide and biphenyl. The clear, slightly yellowish fluid has low viscosity and its solidification point is 12 oC. This is clearly lower than that of the pure compounds. Diphyl is consequently already liquid at room temperature, and can be easily filled into the plant. In contrast to water, its volume decreases when the liquid solidifies. This is an advantage for instruments and pipes: they are not damaged by the solidification of the Diphyl contained in them.

Comprehensive service Heat transfer systems work directly at “the beating heart”, as it were, of the industrial production plant – and it is therefore essential for safety that they function reliably. Every organic heat transfer medium ages due to the high temperature stress, with gradual dissociation reactions. Therefore, both the choice and the maintenance of the heat transfer medium must be exactly attuned to the relevant process and the design of the plant. It is worthwhile discussing the use of heat transfer media with experienced experts – preferably in the planning phase of a heat transfer system. Operating its own production plant, which works with Diphyl heat transfer media, for many years has familiarized.

Diphyl remains nearconstant in its properties for thousands of hours of operation, even under tremendous heat. At temperatures above 340 oC, the product is, in fact, unique. Compared with mineral-oil-based heat transfer media, Diphyl guarantees higher thermal stability with optimal heat transfer properties and a long life. Advantageous in the vapor phase In the vapor phase, particularly, Diphyl shows why the mixture of biphenyl and diphenyl oxide proves to be such a good one in practice. The composition of the mixture has an exact boiling point, which manufacturers can make good use of in the vapor phase.

this is often crucial to the quality of the manufactured product. Murdotec Kunststoffe, a Dortmund manufacturer of semi-finished thermoplastic products, makes high-quality plastics for mechanical engineering. The company uses Diphyl DT as the heat transfer medium in production. “In the manufacture of semifinished products from ultra-high molecular weight polyethylene, temperatures between 20 oC and 240oC are required in our pressing plant. Feed temperatures and film temperatures above 300 oC in the heating system and low viscosity at temperatures below 40 oC were the deciding reasons for using Diphyl DT. The outstanding service from the LANXESS distributor, Obermeier, from Bad Berleburg further vindicated our decision,” explains Josef Ikemann, CEO of Murdotec Kunststoffe GmbH & Co. KG.

The specialists in the distribution company LANXESS Distribution offer comprehensive pre- and after-sales service in terms of technical application. They also organize workshops for their customers. These are organized in cooperation both with plant manufacturers and pump manufacturers, so the participants receive far-reaching information at the one or two-day workshops.

Agitated Nutsche Filter Dryers The S2 ANFDs are innovatively designed and engineered to help improve plant operational process efficiency. S2 Engg’s ANFDs feature a differential mixing agitator that moves vertically for thorough mixing. It has a series of sharp curved blades that achieve mixing penetration in difficult cakes without causing undue product stress. While moving and lifting the cake media around the vessel, agitation mixing efficiency is achieved through differential velocities. A key benefit of the S2 design is that the dried/semi-dried cake can be washed after filtration by reslurrying the cake within an automated operational cycle for as many times as required. The cake is then discharged by lowering the agitator and rotating it in such a manner that it brings all the cake towards the discharge port. S2 Engg provides integral barrier isolator (glove box) technology for contained discharge and charging operations of hazardous potent and toxic products. The S2 solution minimises any waste cake through innovative equipment design. The automated dual piece ANFD model with detachable filter and bayonet or super clamp design improves filter access, maintenance and cleaning in a highly efficient and labour saving manner.

Products CEW Extruder-Spheroniser The extruder spheroniser is a self-contained compact system for the special purpose of making pellets with GMP compliance. System is specially used for making dense pallets for controlled release solid dosage of oral form with minimum expicients. Extruder is the necessary first step for spheronisation. Extruder is often used to eliminate dust in formulation even when spheronization is not the final objective. The raw material to be extruded is introduced axially from the feed hopper into screw housing where it is exposed to rotating screw which conveys the material towards rotor. Rotor forces the material to pass through the mesh with the effect of scraping impact resulting in formation of cylindrical extrudes. The size of the extruder screen operature will dictate the size of the spheroids. The extrudes are dropped axially from the feed hopper into the spheroniser on the rotating checker plate to get sized; further exposure to the checker plate results in conversion of the extrudes into the shape of spheres, ie, pellets. The groove pattern used for the checkered plate is cross-hatched square pattern, which forms a grid of truncated pyramids on the processing surface.

Products CEW COD Analysis System .

As a leading manufacturer in this field, Spectralab Instruments offer a broad range of environment products. COD analysis system is one of them. The chemical oxygen demand (COD) test is used to estimate the amount of organic matter in wastewater. Most types of organic matter are oxidized by a boiling mixture of chromic and sulphuric acid. A sample is refluxed in strong acid solution with a known excess of potassium dichromate. After digestion, the remaining unreduced K 2Cr 2O 7 is titrated with FAS to determine the amount of K 2Cr 2O 7 consumed and the oxidizable organic matter is calculated in terms of oxygen equivalent. The Spectralab COD test system is open reflux method. It is suitable for wide range of wastewater - a large sample size is preferred. This system is followed by the American Standard Test (APHA) method. There is no need to circulate water; precise digestion with digital timer and buzzer; results on display by using COD Titrator Model CT-15 are some of its features. COD digestor is being used by almost all regulating, environmental institutes and industries. Solid block heated units with provision for 6 and 15 samples at a time using air condensers with uniformity of temperature. COD titrator is a microprocessor-based design that speeds up the titration process giving advantage like automation, accuracy, result in storage, printout, etc. For details contact: Spectralab Instruments Pvt Ltd W-446, Rabale MIDC Rabale, Navi Mumbai 400 701 Tel: 022-62556868, 65015757 E-mail: marketing@spectralab.biz / sales@spectralab.biz or Circle Readers’ Service Card 38

Batch Mixer The batch mixer operates on the hurling and whirling principle introduced by Lodige to the mixing technology and technical literature. The mixing elements ensure constant and total involvement of all product particles - preventing the formation of dead or low movement zones. In that way components of extremely different bulk density and structure can be mixed; even mixing in of aerosils for example is achieved homogenously and without demixing. The resultant individualisation of the particles in the mix (fluid bed) allows the addition of liquids and coating of the particles with ease. If necessary, high-speed choppers provide additional support of the mixing process. Ploughshare Shovels can be modified for intensive and gentle mixing of fragile components even at low speeds. Reducing the peripheral speed to <1 m/ sec is possible, depending on the product properties. Pastes and pumpable mixture can be processed with suitably adjusted mixing elements.

CEW Project Update

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

CHEMICALS Coal India is planning a ` 10,000-crore joint venture along with GAIL India, Rashtriya Chemicals & Fertilizers (RCF) and The Fertilizer Corpn of India Ltd (FCIL) to set up a urea and ammonium nitrate chemicals complex that will run on gasified coal. Coal India has appointed Projects and Development India (PDIL) to conduct a feasibility study on the project. The plan is to use around 6-million tonnes of coal from coalfields at Talcher in Odisha and manufacture about 3-lakh tonnes of urea annually and around 300-400 tonnes of ammonium nitrate per day. Ammonium nitrate is the principal ingredient for making explosives used as blasting material at coal mines. The country is facing a crunch in the supply of ammonium nitrate and explosive suppliers often jack up prices, resulting in higher input costs for the company. Songwon Industrial Co Ltd 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. AkzoNobel a Dutch specialty chemicals company and Atul Ltd have agreed to jointly set up a manufacturing plant for monochloroacetic acid (MCA) at Atul’s facility in Gujarat. Each partner will hold a 50 per cent stake in the venture. The partnership will build on Atul's status as a leading global supplier of the herbicide 2,4-D (which uses MCA as a key raw material), and AkzoNobel’s leading global position in MCA market, with plants in the Netherlands, China, Japan and the US. The investment is subject to regulatory approvals and signing of final agreements. The partnership will use chlorine and hydrogen manufactured by Atul to produce the monochloroacetic acid, taking advantage of both Atul's existing infrastructure and the leading ecofriendly hydrogenation technology supplied by AkzoNobel. From an initial annual capacity of 32-kilotonnes (KT) at start-up, the plant has been designed for future expansion to 60-KT. The plant will produce enough MCA to meet the captive requirement of Atul; AkzoNobel will market the rest of it, primarily in India. Monochloroacetic acid is an essential building block in the chemical industry and is used in a wide variety of chemicals. For example, AkzoNobel customers use MCA to produce thickening agents for the food, oil, mining, personal care and detergent industries. The product is also used in agrochemicals, adhesives, pharmaceuticals, thermo-stabilizers, surfactants and cosmetics. Camlin Fine Sciences Ltd, which offers shelf-life solutions (anti-oxidants and intermediates), performance chemicals and aroma chemicals, has received environmental clearance from the State Level Environment Impact Assessment Authority of Gujarat for setting up a manufacturing 60 • March 2018

facility for hydroquinone (HQ) and catechol and their down-stream products at Dahej SEZ. The Dahej plant will expand capacities and provide CFS with a base to manufacture hydroquinone and catechol in India. The plant will also help Camlin Fine Sciences to add capacity for manufacturing of vanillin, for which catechol is a key raw material. The company expects to commission the Dahej plant in FY18. The plant will have capacity to produce 9,000-metric tonne per annum (MTPA) and 6,000-MTPA of HQ and catechol, respectively. Currently, food grade anti-oxidants account for approximately 56 per cent of CFS revenues in FY16, performance chemicals (PC) contribute about 22 per cent, diphenols (HQ and catechol) constituting 18 per cent while aroma chemicals (vanillin) accounting for 3 per cent. SRF is planning to invest ` 3,500-crore over the next four years, 70 per cent of which would go into its fast-growing chemicals business, to cater to rising global demand. SRF, which exports 90 per cent of its chemicals and counts global biggies as its clients, has over the years steered its focus away from technical textiles to chemicals, where it has witnessed a rapid revenue growth and fat operating margin. LyondellBasell, one of the world's largest plastics, chemical and refining companies, on April 7, 2016 completed the previously announced acquisition of the polypropylene (PP) compounding assets of Zylog Plastalloys Pvt Ltd. The company entered into a definitive agreement to acquire Zylog’s PP compounding assets in November 2015. LyondellBasell has supplied the Indian market through imports and tolling arrangements since 2009. In October 2015, LyondellBasell acquired SJS Plastiblends Pvt Ltd’s PP compounding business which is located in Aurangabad, Maharashtra. With the acquisition of Zylog’s manufacturing operations in Sinnar, Maharashtra, and Chennai, Tamil Nadu, LyondellBasell is now the third largest producer of PP compounds in India with an annual capacity of 44,000-metric tonnes. In addition to the already existing product lines offered at these sites, LyondellBasell will produce its Hostacom glass fibre-reinforced, mineral filled and unfilled coloured grades as well as Hifax high impact thermoplastic olefins. These compounds are used to manufacture automotive parts, home appliances and other products. The manufacturing facilities in India are owned and operated by Basell Polyolefins India Pvt Ltd, a wholly-owned subsidiary of LyondellBasell. Bodal Chemicals of Ahmedabad has received environmental clearance (EC) from the Ministry of Environment, Forests & Climate Change for the expansion of dyes and dyes intermediates manufacturing facility located at Vadodara, Gujarat. The company is expanding its dyes and intermediates manufacturing capacity from 2,200-metric tonne per month (MTPM) to 6,000-MTPM, and set up a co-generation power plant (5-MW) in Gujarat. Bodal Chemicals, one of the leading manufacturers of dyes and dyes intermediates in the country, has the capacity to manufacture over 25 varieties of dye intermediates and around 150 variants in dyestuff which are mainly used as raw material in textile, leather, paper and other dye consuming industries. Out of the total production, the company exports about 40 per cent to more than 35 countries across the world. Chemical Engineering World

Project Update CEW Perstorp a Swedish specialty chemicals firm is planning to set up a manufacturing facility for pentaerythritol (penta) in Maharashtra. To evaluate the opportunity to invest in a new world scale production plant for penta in India, the company has signed an MoU with Maharashtra Industrial Development Corporation (MIDC). Pentaerythritol, a white crystalline polyhydric alcohol containing four primary hydroxyl groups, is used as building blocks in alkyd resins for coatings, radiation curing monomers, polyurethanes, rosin esters, synthetic lubricants and explosives. Perstorp currently manufactures producing penta in three different production plants in Germany, the US and Sweden. The related market for coatings in India is growing fast in the country. Building a world scale production plant will be yet another important part of Perstorpâ&#x20AC;&#x2122;s ambitious plan to strengthen the position in the Asian market. In July 2015, Perstorp acquired the penta business from Koei Chemical Co Ltd, a Japanese chemicals producer. IOL Chemicals & Pharmaceuticals Ltd (IOLCP), a producer of active pharmaceutical ingredients (APIs), has increased the production capacity of ibuprofen to 6,200-tonnes per annum (TPA) at Barnala plant in Punjab. Expansion follows a de-bottlenecking project undertaken by the company at an estimated cost of ` 24-crores. IOL Chemicals already exports ibuprofen, a non-steroidal anti-inflammatory drug (NSAID) used as painkiller, to regulated and emerging markets, ie, Europe, Latin America, Middle East, etc. With the recent approval from US FDA, the company is expanding its ibuprofen business in the US as well. Being the only integrated ibuprofen player globally, IOL Chemicals aims to build and sustain the growth of its APIs business in coming years by exploring the higher value regulated markets. MINING Singareni Collieries Co Ltd (SCCL) the State-owned coal mining giant has initiated preparations to start Koyagudem Opencast Project-III (KOC-III) in Lingala Koyagudem coal belt of Godavari valley coal-field in Tekulapally Mandal soon. The extractable reserves in the KOC-III are estimated to be around 111.98-million tonnes as against the estimated geological reserves of 146.81-MT. The KOC-III project is expected to produce around 3.6-million tonnes per annum, SCCL sources said. In pursuit of its aggressive growth strategy, the SCCL has drawn up ambitious plans to open 31 coal mines including 20 OCPs and 11 underground mines in the next five years. It presently has 30 underground mines and 16 OCPs spread across the vast Godavari valley coalfield spanning Bhadradri-Kothagudem, Khammam, Karimnagar, Adilabad and a few other districts in the State. The company has set a coal production target of 66.06-million tonnes for the current fiscal. The company is aiming to set new benchmarks in coal production, dispatches and overburden removal besides enhancing the coal production capacity to around 900-lakh tonnes by 2020-2021. The SCCL has reportedly obtained the mandatory forest clearance from the Central government agencies concerned for the KOC-III. The project envisages use of 1,158-hectares of forest land and 448-hectares of non-forest land. The upcoming KOC-III, which is surrounded by the Koyagudem OCP-II, is expected to augment coal production in Yellandu area of the SCCL. The project is likely to be opened in the first week of July this year. GVMC has initiated a process to take up bio-mining of the accumulated waste renewing its efforts to re-mediate the solid waste dump-yard at Kapuluppada. To begin with bio-mining is proposed to be taken up in five acres of the dump-yard. GVMC has sought the involvement of private companies under corporate social responsibility (CSR) or by investing Chemical Engineering World

money to salvage the dump yard to which garbage is being transported for nearly two decades and piled up there. About 60 of the 100 acres in the dump yard has been filled up, according to officials. The cost of bio-mining is roughly put at ` 400 a tonne going by the experience of other civic bodies. With the city generating about 1,000 tonnes of garbage the cost comes to a whopping ` 4 lakh a day. Spending ` 1 crore a month on fuel alone to transport the solid waste to the dumpyard, GVMC has recently come out with plans to set up organic waste converters at six Rythu Bazars and Poorna Market and asked bulk generators like hotels to go in for OWCs. Also separation of waste in 72 colonies of as many wards has also been taken up. The Solid Waste Management Rules 2016 lay down that local bodies should investigate and analyse all old open dump-sites and existing operational dumpsites for their potential of bio-mining and bio-remediation. The rules also specify that only non-usable, non-recyclable, no-biodegradable and non-reactive inert waste and pre-processing rejects and residues from waste-processing facilities should go to sanitary land-fill. In bio-mining, the waste is levelled first and recyclables removed from it. The waste is then sieved and material useful for compost is again separated from it. The remaining waste goes to the landfill. NTPC Ltd the State-owned power generator hopes its captive coal production will reach 100-million tonne (MT) as soon as its five coal blocks commence operations, aided by faster regulatory clearances and the part-privatization model of Mine Development and Operator (MDO). The success of the plan would determine fuel security of the operations of India's largest power producer. KIOCL will revive mining after a decade in Karnataka, after the State granted the company a lease of over 474 hectares at Devadaru hills in Ballari. 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. The company's blast furnace Unit having a capacity of 216,000 tonnes of pig iron is ready for operation for producing foundry grade pig iron adding towards its profitability in the coming financial year. 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. 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. March 2018 â&#x20AC;˘ 61

CEW Project Update OIL & GAS Integrated Refinery Expansion Project (IREP) of BPCL Kochi Refinery, aimed at producing eco-friendly petrol and diesel conforming to Bharat Stage IV Standards, are nearing completion. The IREP envisages setting up of major units to enhance the refining capacity of Kochi refinery by 6-million tonnes at a cost of ` 16,500-crore. Pursuant to the mechanical completion of the process units, the commissioning activities are being taken up. So far, crude distillation unit, vacuum distillation unit, diesel hydro treating unit, vacuum gas oil hydro treating unit, sulphur recovery units and delayed coker unit have been commissioned. The commissioning of the remaining major IREP units, fluidized catalytic cracking unit (FCCU) and naphtha hydro treater-isomerization unit are being taken up now. Under IREP, BPCL Kochi Refinery has commissioned a state-of-the-art demountable flare. With a height of around 150 metres, the flare is visible over a greater area of the city and there has been an increased rate of flaring at times from the refinery during commissioning. The flare system which is mandatory in industrial plants such as petroleum refineries is a safety system to protect against the dangers of over-pressuring refinery plant equipment. The commissioning activities are expected to go on till the end of September IOC, HPCL and BPCL are set to form a company, Western India Refineries and Petrochemicals, to execute a $40-billion refinery project in Maharashtra. The three companies had in June signed a joint venture agreement for setting up a 60 million tonne refinerycum-petrochemicals complex at Babulwadi, a village in Maharashtra’s Ratnagiri district. The refinery, expected to be commissioned by 2022, will have flexibility to process a wide spectrum of light and heavy crude oil grades and will be designed for Euro VI and grades of transportation fuel above that. According to the MoU among the companies, IOC will have a 50 per cent stake in the refinery complex, and HPCL and BPCL will hold 25 per cent each. The main complex on 14,000 acres will be at Babulwadi and another 1,000 acre storage and port facility will come up 15 km away on the coast. The largest public sector refinery in India is IOC’s 15-million tonne Paradip refinery in Odisha. The world’s largest single location refinery of 33-million tonnes is run by the Reliance Industries at Jamnagar in Gujarat. Reliance Industries has another 27-million tonne capacity in the Jamnagar special economic zone. India has refining capacity of 232-million tonnes, about 38-million tonnes more than the country’s demand of 194.2-million tonnes in 2016-17. Petroleum Minister had suggested the setting up of a mega refinery in 2015 because India’s fuel demand is likely to touch 458-million tonnes by 2040, according to estimates by the International Energy Agency. Petronas the Malaysia's national oil company plans to look for equity partnerships in the liquefied natural gas (LNG) infrastructure segment in India. To expand its presence in the country, the company is also looking to secure long term LNG supply contracts. With over 30-million tonnes per annum supply capacity, Petronas is currently the third largest LNG player globally. However with around 15 LNG cargoes delivered to India, its exposure to India's LNG business so far is insignificant. At present, the company's LNG exposure to India is through the spot market. However, the company will focus on procuring long term LNG contracts in India 62 • March 2018

GAIL the gas transmission major recently launched the ` 6,283-crore Bengaluru City Gas Distribution (CGD) project. The project is expected to cover 4,395 sq km in urban and rural Bengaluru, broadly covering eight sectors - Nelamangala, Dod Ballapur, Devanahalli, Hosakote, Bengaluru East, Bengaluru North, Bengaluru South and Anekal. As part of the project, about 60 Compressed Natural Gas (CNG) stations are to be set up. The project will provide cheaper fuel for the transport sector and also facilitate a healthy lifestyle by creating a pollution-free environment. During the event, GAIL also launched a mobile app to provide a one-stop platform for customers to view/pay PNG bills, locate CNG stations, know about the benefits of CNG/PNG and get emergency instructions. Oil Marketing Companies (OMCs) like Indian Oil Corporation (IOC), Bharat Petroleum Corporation and Hindustan Petroleum Corporation are set to jointly add ` 25,000-` 30,000-crore to expand their liquefied petroleum gas (LPG) infrastructure in the next three years. The investment push is aimed at achieving 95 per cent LPG penetration in the country by 2020. Currently, India is the second largest LPG consumer in the world with the government adding 60-million connections in the past two years. In 2016-17 only, the country added 20-million connections under PMUY and another 10.25-million connections through the non-Ujjwala route. Under the PMUY scheme, the government is looking to provide 50-million gas connections in three years, for which the government has allocated ` 8,000-crore. The government support comes to the tune of ` 1,600 for each family. Numaligarh Refinery Ltd (NRL) signed a MoU with Paradip Port Trust (PPT) and Indian Oil Corpn Ltd (IOCL) for imports of crude oil through the major port. The crude oil imports are meant for catering to NRL’s capacity expansion wherein it is augmenting capacity of its refinery at Numaligarh (Assam) to 9-million tonne per annum, from 3-MTPA now. Under NRL’s proposed refinery expansion project, a 28-inch diameter, 1,400-km crude oil pipeline of 1-MTPA capacity will be laid for transporting 6-MTPA of imported crude oil from Paradip Port in Odisha to Numaligarh in Assam. The MoU provides for utilising IOCL’s spare capacity of existing SPMs (Single Point Mooring) at Paradip. PPT will extend land space for installation of crude storage tanks, pump house and township at Paradip. This will lead to an estimated investment of ` 1,000-crore in Odisha and generate direct and indirect employment. The tripartiate MoU was signed between Chairman of Paradip Port Trust, Director (Technical) at NRL and Executive Director (Pipelines) of IOCL in the presence of Union minister for Road Transport, Highways and Shipping and Minister Of State for Petroleum & Natural Gas. NRL is a joint venture between Bharat Petroleum Corpn Ltd (BPCL), Oil India Ltd and the Assam government. CEMENT Chettinad Cement Corpn Pvt Ltd and KCP Ltd of Tamil Nadu are planning to invest ` 1,350-crore and ` 531-crore respectively to establish their new units in the Andhra Pradesh State. The State Investment Promotion Board headed by Andhra Pradesh Chief Minister has cleared six investment proposals, including these two, involving a total investment commitment of ` 3,303-crore. Chettinad will set up cement grinding unit on 75 acres and a manufacturing plant on 1,000 acres of land in Vizag and Guntur Districts respectively. The Chemical Engineering World

Project Update CEW mega project will start production in March 2019. KCP Ltd will be setting up a unit on 100 acres of land in Krishna District with the first phase scheduled to start operations in a year's time. The cement industry in South India in general, and in Telangana and Andhra Pradesh in particular, is facing a huge capacity overhang with an installed base of around 150-million tonnes against a total demand of around 60-million tonnes. An additional 20-million tonnes goes to the neighbouring markets in the eastern and western parts of the country from here. The two Telugu-speaking States together possess more than 30 per cent of the country's limestone reserves, making them attractive destinations for cement companies. Among the other major investment proposals, Hyderabad-based Rain Group, which also has cement manufacturing operations, has expressed interest in establishing a calcined petroleum coke plant, a cement grinding unit, an R&D facility and a waste heat recovery power plant at Achutapuram SEZ in Visakhapatnam district, the government said. The company proposes to invest ` 1,096-crore in these projects Birla Corpn will set up a 3-million tonnes per annum (MTPA) clinker plant in Maharashtra to help it expand its presence in the western India market. The firm wants to build on the recent acquisition of the ` 4,800 crore cement business of Reliance Infrastructure (RInfra) through which it will also get mining lease of Mukutban limestone mines situated in the Yavatmal district of Maharashtra. Besides, the firm expects that the acquisition will help it become a pan-India player in the foreseeable future. Cement accounted for 91.34 per cent of its total sales in 201516. The company's turnover stood at ` 3,768.42-crore in the period. Maharashtra has limestone reserves of around 1,371.43-million tonnes with extensive deposits located in Yavatmal, Chandrapur and Gadchiroli Districts. Mukutban mines are known for its cement-grade deposits of limestone. In the report, Birla Corp had said that its profitability in 201516 fiscal was impacted due to outsourcing of limestone at higher prices, which is a key ingredient in making cement. Reliance Cement Co Pvt Ltd (RCCPL) has 3 plants located at Maihar in Madhya Pradesh (MP), Kundanganj in Uttar Pradesh (UP) and Butibori in Maharashtra. It has a total installed capacity of 5.8-MTPA and 3.30-MTPA respectively. Birla Corp has seven cement plants, two each at Satna (MP), Chanderia (Rajasthan) and Durgapur (West Bengal) and one at Raebareli (UP). It has a total cement capacity of 10-MTPA. With this acquisition, its total capacity will increase to over 15-MTPA. Burnpur Cement plans to invest ` 500-crore for expansion of its production capacity to 3-million tonnes per annum (MTPA) in the next 3-4 years. The cement producer has two plants, one in Asansol in West Bengal and the other in Patratu district in Jharkhand. Each plant has 0.3-MTPA installed capacity. The company also aims to increase its sales revenue to ` 250-crore in the next year from ` 100-crore in the last fiscal. The cement producer plans to build a 2-MTPA greenfield plant in West Bengal. The company has already bagged two limestone mines through auction mode. JSW Cement, a unit of Sajjan Jindal-led JSW Group, plans to bring down its cement-making cost by as much as three-fourths by setting up grinding units closer to markets, in contrast to the traditional model of clinker units placed near the source of raw material. The new units will use clinker imported from countries that have a surplus, Chemical Engineering World

thus allowing JSW Cement to add 1-tonne of capacity at about ` 180-crore, against ` 840-crore required to set up a similar capacity under the traditional model. The company plans to establish several such grinding units on the country's east coast in West Bengal and Odisha, taking its cement capacity up by more than 14-million tonne (MT) to 20-MT by 2020. Jaypee Cement, a subsidiary of Jaypee Associates won the Majra mine in Maharashtra for ` 1,230 per tonne. The extractable reserves of the mine are 14.92-tonne and the floor price at which bidding started was ` 800 per tonne. The company will pay the State government ` 1,853.26-crore for a period of 30 years. Jaypee Cement had earlier won Mandla South in Madhya Pradesh during the first phase of auction at a price of ` 1,852 per tonne. As a group, this is Jaypee Associates’ fourth win in the three phases of auction till yet. It had earlier won one non-power block Mandla South during the first phase and one non-power block Mandla North and one power block Amelia North, both in MP during the second phase. Majra mine was earlier allotted to Gondwana Ispat before a Supreme Court order last August struck down all coal block allocations made over the past two decades. The first phase was for Schedule-III producing power and non-power blocks and subsequent phases were for Schedule-II about to produce blocks. The third phase of auction was strictly for unregulated sector, ie, iron, steel and cements manufacturing. There was forward bidding model for these blocks wherein the bidders quoted above the floor price and the highest bidder won the block. This phase had blocks which could not be auctioned in the earlier phases as they were involved in any legal tussles or whose allocation was cancelled by the government. The earlier two phases of the coal auction for 40 producing coal blocks were held in February-April 2015 fetching the mine bearing States cumulative revenue of ` 2.85-lakh crore for a period of 30 years. Both power and non-power sector participated in the same. FERTILIZER Nagarjuna Fertilizers and Chemicals Ltd is planning to invest ` 5,000-crore in expanding its fertilizer facility in Kakinada by setting up a 1.3-million tonne per annum brownfield urea project. The new expansion facility is slated to come up within the existing complex. It will take two years to complete. The company hopes to raise funds for the expansion through a combination of debt, equity and internal accruals Greenstar Fertilizers Ltd is kicking off ` 135-crore expansion of its phosphoric acid unit to meet the raw material demand for Di-ammonium Phosphate (DAP) production. The project is coming up on its existing facility at Tuticorin in south Tamil Nadu where it has adequate land for the expansion, according to the public hearing announcement by the TN Pollution Control Board. Greenstar Fertilizers, promoted by son of the promoter of SPIC, acquired the phosphatic businesses of SPIC, through a business transfer agreement in October 2011. Under this agreement, the DAP, aluminium fluoride, SSP units, sulphuric acid and phosphoric acid units came under Greentstar Fertilizers’ fold. Urea production was retained with SPIC. In the proposed project, the raw materials handling will more than double with rock phosphate handling increasing to 62,100 tonnes a month and sulphuric acid capacity to 54,900 tonnes. Phosphoric acid output will double to 1.5 lakh tonnes. The raw material for the proposed project will be brought March 2018 • 63

OCP of Morocco and Kribhco have entered into a 50:50 joint venture to develop a greenfield NPK fertiliser plant at Krishnapatnam in Andhra Pradesh. This fertiliser plant will require an initial investment of approx $230 million and have an annual production capacity of 1.2-MT of NPK fertilisers. Furthermore, the project also includes the development of logistical infrastructure in the region. The venture would provide indigenous NPK fertilisers to Indian farmers by leveraging Kribhco’s deep knowledge of the market and farmers’ requirement, as well as OCP’s expertise. The venture is expected to be the first step in a broader strategic cooperation between both the groups that could include Kribhco’s investment in a phosphoric acid unit in Morocco. Indian Farmers Fertilizer Cooperative (IFFCO) has awarded a ` 300-crore contract to Essar Projects, an engineering procurement and construction (EPC) company, for construction of a new phospho gypsum stack at IFFCO’s Paradip unit in Odisha, which is India’s largest phosphatic fertiliser complex.This is Essar Projects’ fourth major contract from the Indian fertiliser industry giant. The project will be completed in two phases. Phase I, valued at about ` 190-crore, involves completion of approx 60 per cent of the total construction and must be completed in 20 months. The second phase involves construction of the remaining 40 per cent and will have to be completed in 10 months. Until date, the company has, completed three major projects for IFFCO Paradip, handing them over well ahead of the scheduled date of completion. Essar Projects’ previous contracts for IFFCO includes construction and commissioning of two 2,500-MT DAP/NAP silo, revamping of an existing sulphur silo, and EPC and commissioning of the eighth evaporator system of the phosphoric acid plant (PAP) at the IFFCO Paradip complex. Essar Projects has been involved in building mega fertiliser projects. It has the distinction of executing India’s first greenfield fertiliser project in recent times, the Matix Fertilizers plant, in Durgapur, West Bengal. The Matix Fertilizers complex is also the largest integrated fertiliser plant in India. NTPC and Coal India Ltd signed a joint venture agreement to form a new company for revival of the fertilizer plants of Fertiliser Corpn of India Ltd at Sindri, Bihar and Gorakhpur, Uttar Pradesh. The joint venture company will set up an ammonia urea plant at each location with a 50:50 equity holding from NTPC and Coal India.Subsequently, strategic partners can be inducted. This is the second time in two years the Coal India Ltd is entering into a joint venture to revive plants in the fertiliser sector. Last year, Coal India Ltd had signed an agreement with GAIL (India) Ltd, Rashtriya Chemicals and Fertilisers Ltd and Fertiliser Corpn of India Ltd to incorporate a firm to set up and operate new ammonia urea complex in Talcher, Odisha. RCF is likely to get clearance from the Public Investment Board (PIB) for establishing a new urea plant at its current manufacturing facility at Thal in Maharashtra with an estimated investment of ` 5,500-crore. As per the proposal, an ammonia-urea plant will be set up at Thal in Maharashtra with a capacity of 1.27-million tonnes per annum at the company's current manufacturing location. According to the source, tender for the plant's engineering and construction has been awarded to a consortium of Technip and L&T. The total estimated cost of the project is at ` 5,500-crore. Public Investment Board (PIB) examines the investment plans put forwarded by the individual ministries in lieu of the respective public sector undertakings. After getting the PIB nod a note would be moved for the cabinet approval. 64 • March 2018

The Mumbai-based PSU's annual urea capacity is more than 2-million tonnes and it also produces various grades of complex fertilisers at its two manufacturing units in Thal and Trombay in Maharashtra. RCF, along with Coal India, GAIL and Fertiliser Corpn of India (FCIL), has also formed a consortium to revive the sick unit of FCIL at Talcher at a cost of ` 8,000-crore to manufacture urea and ammonium nitrate via coal gasification. Ramagundam Urea plant gets green nod from MoEF Committee for the proposed ` 5,465-crore fertiliser plant in Ramagundam, Telangana. National Fertilizers Ltd (NFL), Engineers India Ltd (EIL) and Fertilizer Corpn of India (FCIL) had earlier signed an agreement to form a joint venture company (JVC) for setting up two new - Ammonia and Urea plants at the existing site of Ramagundam Fertilizer plant.The JV formed a new company called Ramagundam Fertilizers and Chemicals Ltd. The gas-based plant which will have the capacity to produce 1.1-million tonnes of urea per annum is expected to be commissioned in 2018-19. ENERGY JIPMER has drawn up an elaborate plan to collaborate with the Renewable Energy Agency of Puducherry (REAP) to commission during the first quarter of 2018, a rooftop solar grid at a cost of ` 7.63-crore. The 1,500 KW roof top solar grip being set up on the institute’s premises will help save ` 1.5-crore in power tariff every year. SPIC is working on setting up a 24-MW floating solar power plant. The idea is to put up the plant in a large water reservoir the company has within its precincts. This was revealed in a conference which was held here recently by the Southern India Chamber of Commerce and Industry (SICCI), an industry body, in collaboration with Aspiration Energy, a Chennai-based renewable energy company. However, it is learnt that the plant would be owned by AM International Holdings, the Singapore-based parent company of SPIC. EDAC Engg will provide the services of building the floating solar plant. AM International will sell most of the power generated by the solar plant to SPIC, though a part of the generation will be sold to the state-owned electricity distribution company. Sources also said that a European bank, with headquarters in France, would provide the debt for the floating solar plant. Floating solar plants are slowly but steadily gaining popularity. These barge-mounted plants have the advantage of not requiring land. The water below keeps the panels cool, enhancing their performance (heat depresses electricity generation by solar modules). Till date, the biggest floating solar plant is the one in the reservoir of the Yamakura dam in Japan, owned by the Japanese company Kyocera. However, many entities, including quite a few in India, have plans. Kerala has a 500-kW floating solar plant, while Andhra Pradesh has the biggest in the country. There have been reports that the Andhra Pradesh government is working on having 100-MW of floating solar power plants, while Maharashtra has expressed an ambition for 1,200-MW. The country has a large potential for floating solar plants, so much so that the entire 100-GW ambition of the government can entirely come on water. The country has close to 5,000 large dams, whose reservoirs spread over nearly 13,000 sq km Bharat Heavy Electricals Ltd has commissioned the fifth 68-MW unit of the Rampur hydro power project in Himachal Pradesh. The project is located on Satluj river. BHEL's scope of work in the project includes supply, erection and commissioning of six 68-MW Francis turbines, among others. According to the statement, nine hydro sets totalling 641-MW were commissioned by BHEL in 2013-14 period. The company is currently executing hydel projects having about 5,000-MW generation capacity.
