National Fertilizers Limited UNIT PROFILE: - National Fertilizers Limited was established on 23rd August 1974 for setting up two fertilizer plants at Bhatinda (Punjab) and Panipat (Haryana) based on partial oxidation of fuel oil. W hen Govt. of India undertook the task of reorganization of fertilizer sector in 1978; the Nangal Unit of Fertilizer Corporation of India was merged with National Fertilizers Limited. Later on NFL executed two numbers gas-based plant at Vijaipur (Madhya Pradesh) on HBJ gas pipeline. National Fertilizers Limited is now operating three fuel oil based plants located at Nangal, Bhatinda and Panipat and two gas based plants, at Vijaipur. The capacity of three fuel oil based plants is; 900 Te/day of Ammonia, and 2*1350 TPD of gas based plant at Vijaipur. 1000 TPD of urea at Nangal, which has been revamped to a capacity of 1448TPD in 2000-01 and 1550 TPD of urea at Bhatinda and Panipat. Capacity of gas-based plant at Vijaipur is 4*1100 TPD of urea. Company at present occupies the position of the largest producer of Nitrogenous fertilizers in the country. National Fertilizers Panipat. The Government of India approved the Panipat Project on 10th February 1975 for implementation. Prime consultants for design, engineering and erection and commissioning of the plants were M/s. Toyo Engineering Corporation of Japan and M/s. Engineers India Limited. Starting from the zero date of 30.4.1975, the feed in was achieved on 1.9.78. The unit went in commercial production from 1.9.1979. In 2001-2002, Panipat unit achieved Ammonia production of 299280 MT (100.77 % of installed capacity) and 511538 MT of urea (100.01 % capacity utilization). The unit has also produced 3104.775 MT Sulphur as by product during the year. Expansion of Panipat unit with Naphtha/LNG based plant of 1350 TPD of Ammonia and 2200 TPD of urea is under consideration by Govt. of India. ii Energy Consumption: Panipat unit consumes fuel oil, LSHS/HPS as feedstock for producing Ammonia as intermediate product and Urea as final products. It also consumes coal and furnace oil in auxiliary boilers for producing steam and generating power in captive power plant for meeting own requirement of power. In addition to captive power generation, provision for import of electricity from Haryana State Electricity Board grid has been made in the original set up of the plant. In 2001-2002, NFL Panipat unit consumed 242267 MT of fuel oil/LSHS/HPS as feed stock, 583198.773 MT of coal in captive power plant boiler and steam boilers, 38110.100 KL of fuel oil in Captive Power Plant and steam boilers and 15780 MW of purchased electricity. The unit has made consistent efforts in reducing the consumption by different ways such as Increase in Capacity Utilization: The unit has achieved more than 100% capacity utilization for the last 5 years except last year i.e. 2000-2001. This could be achieved by innovative management techniques, better maintenance procedures and improved operational methods. This could be achieved even though the plant is 23 years old. In spite of various constraints such as breakdowns, maintenance problems faced due to coal mills, Boiler and more no of equipments in comparison to the latest generation plants, the unit has been able to achieve energy consumption figure of 14.009 Mkcal per tonne of ammonia and 9.174 Mkcal per tonne of urea in 2001– 2002, which is excellent. NFL, Panipat utilized fuels worth Rs.116.83 crores and purchased power worth Rs.8.82 Crores in the year 2001-2002 iii) Energy conservation commitment, policy and set up: National fertilizers Limited, Panipat is wholly committed to conserve energy to the fullest possible extent. Unit is giving utmost importance to energy conservation by optimization of plant operation and process parameters, regular monitoring of fuel consumption, analyzing the reasons of higher consumption and eliminating bottlenecks. Since inception of the plant, unit has strived to improve the specific energy consumptions by way of devising and implementing energy conservation schemes. Company has Energy conservation cell under the Department of Technical Services. E.C.Cell is headed by Dy General Manager (Technical Services). This cell consists of one Ch. Mgr (TS), one Sr. Manager, and two Sr Asstt. Manager and one Asstt. Mgr who coordinate all matters pertaining to energy conservation. Performance of various energy conservation schemes and specific energy consumption of main product is evaluated and is discussed in fortnightly coordinating meeting where all managers including the General Manager (I/C) are present. The action plan required if any is prepared and is implemented. The fertilizer sector is one of the most energy intensive units. About 85% of the total cost of urea is consumed in energy alone. Even a minor reduction in energy consumption results in increasing the profit. Hence, the policy of the organization is to reduce the energy consumption to the minimum. The new schemes are being implemented based on the techno-economic viability. iv) Energy conservation achievements: NFL, Panipat has implemented various energy conservation schemes successfully during last five years. Implementation of these schemes has resulted in improvement in steam consumption rate, boiler efficiency, better process control and optimization etc. A substantial amount of energy has been saved by proper implementation of the energy conservation projects. v) Energy conservation plans and target: Company waits with eagerness for all opportunities coming in the way to conserve the energy to largest possible extent. The following schemes are under implementation for improving the energy performance further. Up gradation of critical control loops with micro processor based control system: Various control loops, which are very critical from consistent operation point of view, are identified and then these control loops are being upgraded to microprocessor based control system. An expenditure of about Rs. 25 lakhs is likely to be incurred on these schemes. Implementation of this scheme would result in increased on stream days of the plant. vi) Environment and Safety: A brief write up on Environment: A chemical factory is likely to produce some effluents in the form solid, liquid or gases, which may or may not be toxic. These effluents have to be necessarily treated before disposal to outside so that the ecological balance is not affected. At Panipat unit, utmost care was taken during the design stage of the plant/units to control all the pollutants at the source. Panipat unit is basically an Ammonia-Urea fertilizer complex having a capacity of 900 MTPD Ammonia & 1550MTPD Urea. There is auxiliary steam generation plant to produce high pressure steam to meet the needs of various processes; utilities plant to meet the requirement of Power; DM water-Cooling Water, etc and Effluent Treatment Plant to treat the liquid effluent. Type of effluents generated and procedure for their treatment are summarized below: A. Effluent Generation 1. Solid Effluents: The solid effluents generated in Ammonia plant on account of thermal cracking of heavy oil in Gasifier is being recycled back to the system as carbon oil after mixing with heavy oil. However, during start up / shutdown and in case of any disturbances in Carbon Recovery Plant, the carbon is being dumped to the LDPE lined (ski ten) nearby ponds in the form of carbon slurry. The dried carbon from the pond is being sold to the out side parties having authorization from Haryana State Pollution Control Board. The other solid effluent generated is ash in coal-fired boilers. The ash collected in ESP’s in the boiler is being dumped out in the form of ash slurry at Dahar pond @ distance of 7 Kms from factory premises. The over flow water from Dahar pond, which meets the MINAS norms, is being utilized for irrigation purpose nearby villagers. The ash slurry pond at Dahar is thoroughly LDPE lined to prevent leaching of pollutants if present. 2. Liquid Effluents: The liquid effluent generated from main process plant Ammonia, Urea plants are diverted to the Effluent Treatment Plant, waste water generated from DM Water plant during the course of regeneration of cat ion and Anion units are also diverted to Effluent Treatment Plant. The Sewage generated in the township as well as in factory premises are also diverted to Effluent Treatment Plant. The Effluent water containing Ammonia and Urea are treated by biological process with the help of other liquid effluent generated in DMW Plant and sewage water. The out going treated water from Effluent Treatment Plant, which meets MINAS norms, is being used for de-ashing purpose in SGP and CPP Boiler. 3. Gaseous Effluent: The gaseous effluent from Ammonia Plant In Ammonia plant two types of gaseous effluent are generated-one during the start up of the plant, which is burnt at 75-meter tall flare stack before release to atmosphere. The other gaseous effluent generated during normal operation of the plant is tail gas, off gases&H2S bearing Claus gas. The tail gas is being utilized in Steam Super heater to super heat the steam produced in Waste Heat Boilers in Ammonia plant, incinerator in Sulphur Recovery plant & in CPP Boiler. A little amount of tail gas is being utilized in flare stack to keep the flame on continuous basis. The off gases, which contains mostly CO2 & N2 and having no heat value is released to atmosphere through the 75-meter tall flare stack. The Claus gas, which is sent to Sulphur Recovery Plant, and elemental Sulphur, @ purity of 99.9% is being extracted by oxidation –reduction process. The effluent gas from Sulphur Recovery Plant after burning in incinerator where heat is being recovered to produce low-pressure steam is vented through a 50-meter tall chimney. The effluent gases from Sulphur Recovery Plant meets MINAS norm. Thus, not only the pollution is controlled but valuable substance i.e. elemental Sulphur is being recovered resulting in saving of foreign exchange. Flue gas from Boiler Chimney: The flue gas from Boiler chimney is vented through 80/90-meter tall chimney from SGP and CPP boilers after passing through electrostatic perpetrator having an efficiency of more than 99%. SPM content in the flue gas in the boiler chimney remains below the MINAS norms. Dust recovery from Urea Plant Urea dust recovery system has been installed at the tope of Prilling Tower 68 meter high. The dust evolved by urea prilling is being scrubbed by spraying water from spray nozzles in a header provided around the prilling tower. The remaining dust after scrubbing operation is being retained by the foam filters provided at the top. There are four Induced Draft Fans provided at the top having a capacity of 1,80,000 Nm3/hr each. The gases effluent so discharged contain less than 50 ppm of urea. Automatic washing of the foam filters is done to further improvement in the existing system. B Ecological balance: To maintain the ecological balance about 2.5 lakhs trees have been planted in and around factory premises, township and CISF colony area. A green belt @ area of 1400 sq meter has also been provided around the factory premises as per the environment control board advice. Besides it a dear park has also been developed in the township and bird century near the factory premises. All these means are very useful to keep the ecological balance To keep a close watch on the performance of pollution control on line monitoring equipments has been provided in various plants. ISO Kinetic stock samplers are monitoring stack emission regularly. This ensures the optimum level of emission at source as well as efficiency of the stacks. Some of the stacks are equipped with on line analyzers like smoke density, carbon monoxide, oxygen and Sulphur dioxide. Ambient air and stack monitoring is also got done by accredited out side agencies from time to time in order to ensure adherence to various emission norms. For the reference of dispersion of air pollutants, a computerized wind monitoring system has been installed at one of the monitoring stations. The system is automatic and computes average wind speed and direction after every ten seconds. In addition to this, max-min temperature, relative humidity, semi fall measurement is also done and the date is recorded continuously. ISO 14001 NFL Panipat is committed to achieve Pollution free environment and balanced ecology by adopting Environmental Management System. The Unit is conducting regular Environmental Audits and compliance with the statutory and legal requirements. Based on the environment Policy of NFL, Panipat the Unit engaged M/S KPMG Quality Registrar for carrying out audit leading to award of ISO 14001-1996 On successful completion of all the audits and statutory requirements, our Unit was recommended for this prestigious award and the Certificate was received on 1st June 2000. “THE AWARD OF ISO 14001-1996 CERTIFICATE TO THE UNIT IS COMMITMENT TO POLLUTION FREE ENVIRONMENT IN AND AROUND THE FACTORY AND SOCIETY AS A WHOLE.” It is a fact that pollution controls having no limits, but our efforts shall never be lacking to achieve lowest emissions.

ENERGY CONSUMPTION NFL Vijaipur Unit consumes Natural Gas (NG) and Liquid fuel Naphtha as raw material/ fuel. Overall Energy Consumption / MT Urea in the year 2001- 2002 is 5.984 Gcal/MT of Urea which Is lower than the previous year figure of 6.008 Gcal/MT of Urea. In the year 2001-2002, annual electricity cost was Rs.41.20 Crores which is higher than previous year value of Rs.37.49 Crores. This was due to increase in usage of electric motors. In the year 2001-2002 Naphtha usages was high due to Natural Gas Limitation from M/s. GAIL. Energy consumption (Cost Of Natural Gas & Naphtha) was 90% of the total manufacturing cost. 3. ENERGY CONSERVATION COMMITMENTS, POLICY AND SET UP MANAGEMENT COMMITMENT TOWARDS ENERGY CONSERVATION: Being one of the largest producers of Nitrogenous fertilizers in the country, NFL visualized the importance of energy conservation and consumption in the fertilizer industry and took the lead in this direction by establishing Energy Conservation Cells at the Corporate Office and at the Unit levels. The underlying policy is four pronged 1. Energy monitoring and control 2. New technology absorption and adaptation 3. Carry out Energy audits both internal as well as external 4. Energy consumption benchmarking with a target to achieve the best. The basic objectives of this energy cell are: -Monitoring daily and monthly energy consumption data from each plant. - Evaluation of energy performance by Steam and Material balance of each plant - Check list of steam traps, insulation, leakages, vent valve passing . -Machine and plant efficiency calculation- heat exchangers etc. -Process parameters and catalyst performance evaluation. - Inform the plant for remedial measures / actions. - Prepare action plans based on energy consumption analysis. In addition to the regular monthly energy audit by an in-house technical group, energy audit activities are also planned on the basis of energy audit conducted at an appropriate interval of time through out side agencies. CORPORATE POLICY OF UNIT ON ENERGY CONSERVATION: Energy conservation as corporate policy caries the highest importance in N.F.L. The energy consumption norms have been fixed for each operation and are closely monitored on daily, monthly, quarterly and yearly basis. Based on the energy audit studies, the following broad strategy was formulated for the reduction of energy consumption by NFL. -Increase capacity utilization -Increase On-stream efficiency and On-stream days -Improve operation and maintenance practices and implement other good house keeping measures - Implementation of major modifications and retrofits - Maximum utilization of waste and by products - Training and Motivation on energy conservation. 4. ENERGY CONSERVATION ACHIEVEMENTS Over the years since commissioning of plants, persistent efforts have been made to improve energy performances & various energy saving schemes have been implemented which have resulted in considerable monetary savings. With the commissioning of Vijaipur-II, energy level has further reduced. In the year 2001-2002 energy consumption was 5.984 Mkcal/Ton of Urea which was lower than the value for the year 2000-2001. Though normal industry practice is to take major turnaround every year, we have improved the reliability of plants and machinery by various past modifications and the shut-downs have been reduced to once in two years thereby increasing the on-stream days of the plant at optimum loads. In the year following energy conservation measures were implemented successfully. Brief description is listed below. In house study by technical services on Performance of Pumps in the Ammonia / Urea / Offsites facilities. On the basis of the study it was found that at various points it was possible with slight modifications to stop extra pumps which were in line. On the basis of pump report following pumps were stopped. Urea-I Plant: Two number pumps(P-6/P-22) supplying flushing condensate at various points were provided in Urea Plants. As per inhouse study Medium Pressure Flushing Pump P-6 was stopped by providing interconnection between P-6 and P-22 pumps. Similarly two number pumps (P-6/P-13 ) for LP Flushing was provided, one for exporting the condensate and another for supplying LP condensate at various flushing points of Urea Plant. As per inhouse study Medium Pressure Flushing Pump P-10 was stopped by providing interconnection between P-13 and P-10 pumps. Offsites: Two number service water pumps were required to be run to maintain the required pressure in the complex. With the running of both pumps capacity was not optimally utilized. With optimisation at consumption points it second service pump was stopped and around 22 Kwh power was saved. 5. ENERGY CONSERVATION PLANS AND TARGETS Though the energy conservation is a continuous and everlasting process, NFL, Vijaipur has been making all out efforts in the field of energy saving. With a view to improving the energy performance further and conserving energy, number of energy saving schemes, based on recommendations of energy audit, are planned to be implemented. Some of them are given below: (i) Replacement of two numbers back pressure turbine with motors, (ii) Replacement of GRP blades with FRP in Urea-I cooling tower fans. (iii) Replacement of defective steam traps. Further a Comprehensive in-house study is being undertaken to reduce energy consumption of Line-I Plants. Measures, which were being considered for implementation and are at various stages of approval stage are listed below: · Replacement of CO2 Compressor Turbine from 40ata to 105ata. · Installation of High Efficiency trays in Urea Reactors. · Augmentation of Sweet water cooling system of synthesis section. · Revamp of Benfield section. · Installation of DCS control system for Line-I Plants. 6. ENVIRONMENTS AND SAFETY 6.1 ENVIRONMENT National Fertilizers Limited, Vijaipur is an ISO-14001 unit. This certification has been given by KPMG Netherlands based on the audit carried out by them in the year 1998-99. At NFL, Vijaipur, utmost importance is given to 'Environment Protection' in and around the complex. The NFL management thought of an elaborate system of environment monitoring, treatment and controlled discharge of effluents right from the planning stage of the Vijaipur-I project. CONCEPT OF ZERO EFFLUENT DISCHARGE A unique concept of zero effluent discharge was adopted at N.F.L. Vijaipur due to the inadequate supply of water due to non-availability of large water sources near the project. The treated wastewater from the factory is exclusively used for irrigation purposes in the green belts as well as in kitchen garden with excellent results. ENVIRONMENT MONITORING CELL There is a cell called “Environment Monitoring & Control” which exclusively looks after environmental aspects. National Fertilizers Limited Vijaipur has won various environmental awards in view of excellent performance in pollution control and environment protection. It has won Annual State level award 2000 on Environment by Ministry of Housing and Environment and Jawaharlal Nehru Memorial National Award for year–2000 for pollution control and energy conservation methods. AIR POLLUTION CONTROL The generation of dust in Urea Prilling Tower is kept well within the stipulated limits by using a rotary bucket for prilling. Further the prilling towers are constructed sufficiently tall high (98 meter & 104 Mtr respectively in Line I & Line II) to facilitate proper disbursement of the dust from the prilling tower exhaust. The ground level dust concentration is well within the limits. Dust extraction systems have also been installed to reduce urea dust in the vicinity of plant. Natural gas or NGL/Naphtha is used as fuel in all the furnaces at NFL, Vijaipur. Since natural gas contains almost nil (<1ppm) sulfur and sulfur based compounds, the SO2 and S.P.M. are almost negligible in stack emissions. The concentration of NOX is also well within stipulated the limits as low NOX burners have been used in furnaces. GREEN BELT DEVELOPMENT To improve the ecological balance of environment an extensive programme has been taken up for tree plantation in and around the NFL Complex. About 2,00,000 trees of 86 different species have been planted so far by NFL Management covering approx. 206 hectares of land. In addition to the a forestation work, horticulture development has been taken up in an area of about 30 hectares. Based on the suggestions given by National Environmental Engineering Research Institute,(NEERI) Nagpur, the fast growing trees with thick canopy cover and thick perennial foliage have been planted. This barren stretch of land which had no tree to start with has now about 2,00,000 trees and the greenery around the complex is testimony to the efforts made by NFL for its development. 6.2 SAFETY At National Fertilizers Limited, Vijaipur, there is a constant endeavor to improve safety and working conditions. The safety policy of the company aims at elimination of Industrial Accidents in order to achieve the same, National Fertilizers Limited, Vijaipur has adopted several measures, e.g. integration of safety with various departments, provision of safe working conditions, familiarization of the employees with the general and special safety practices and enforcing them in their work place, deputation of employees in various in house as well as external programmes, celebration of safety day. Safety audit is conducted every year by external agencies. M/s PDIL, NOIDA, conducted safety audit for the year 2001-2002. National Fertilizers Limited, Vijaipur has won vide acclaims in the field of safety for maintaining high sta achieving record accident free period.
