PRESENTATION ON IFFCO (INDIAN FARMERS FERTILIZER CO-OPERATIVE LTD.)
SAURABH SINGH CHAUHANTRAINING DIRECTOR 11204730MR. D.KALIA
-:INTRODUCTION:-
The fertilizer in India consists of three major players:
The Government owned Public Sector undertakings Cooperative Societies like IFFCO units from Private sector.
The fertilizer industry has organized itself through Fertilizer Association India (FAI) to coordinate with the Government of India to achieve the macro-economic objectives related to agricultural sector and to provide other services.

IFFCO, is the world's largest fertiliser cooperative federation based in India which is registered as a Multistate Cooperative Society. On 3 November 1967 IFFCO was registered as a Multi-unit Co-operative Society.
Five units of IFFCO are:- Kalol Kandla Phulpur Aonla Paradeep
Aonla unit of IFFCO is one of the five natural gas based fertilizer plants to be setup in the country on HBJ( HAZIRA-BIZAPUR- JAGDISHPUR) pipeline which runs through states.
Two production units Urea-I and Urea-II and each of these two units has two sub units.
Storage of NEPTHA as a alternate fuel.
UREA MANUFACTURING PLANT
STEAM AND POWER GENERATION PLANT OFFSITE PLANT AMMONIA PLANT UREA PLANT
STEAM GENERATION PLANT
All the major rotating equipments of ammonia and urea plant are driven by electric motors ,so steam and power generators are required.
Two gas turbine generators. Capacity of 18 MW each. Involves three main sections ; Compressor , Combustion system ,
Turbine.
OFFSITE PLANT
To support the production plant Without it ,there is no existence of production plant. Offsite plants are LIKE :- RAW WATER SYSTEM WATER TREATEMENT PLANT COOLING TOWERS AMMONIA STORAGE PLANT
RAW WATER STORAGE
CHARACTERSTICS OF STORAGE TANK:- Total storage capacity= 32760 cubic meter one raw water storage tank=33696 cubic meter volume of storage tank= 78m * 108m *45m
DM PLANT
Underground water contains little impurities and high concentration of dissolved salts.
To get rid of these impurities (chlorides, sulphates , carbonates, bicarbonates) DM plant is used.
The water that could be used in plant should have following specifications:-
ph = 6.8 to 7.3 silica <0.02 ppm total electrolytes =0.1 ppm Hardness = nil
COOLING TOWERS
Most important unit of any chemical plant Cold fluid is water and the plant to cool the water is called the
cooling tower. A type of heat exchanger In IFFCO , Heat absorbing fluid is AIR and heat releasing fluid is water.
EFFLUENT TREATMENT PLANT
INSTRUMENT AIR PLANT
Atmospheric air can’t be used directly to open and close valves Air used in plants is moisture and impurities free and is known as
instrument air.
INERT GAS PLANT Inert gas (N2) is generated, which is used for purging and for Production of
Ammonia in Ammonia Plant.
AMMONIA STORAGE
In case of any problem in the Ammonia Plant, Ammonia could be supplied from these tanks.
Ammonia is stored at a gage pressure of 400 mm water at a temperature of -33 °C in liquid form. Gaseous Ammonia is continuously returned back to Ammonia Plant.
Storage Tank
AMMONIA PLANT
To get the Ammonia manufactured, the following steps should be followed:
Desulphurization High Pressure Catalytic Reforming Water Gas shift reaction Carbon Dioxide absorption and stripping Ammonia Synthesis Refrigeration
Continued…
REFRIGERATION
The effluent from the ammonia converter is cooled successively with incoming feed gas, cooling water, and refrigerated ammonia liquid.
At IFFCO refrigeration circuit is three level chiller (chiller cools but don’t change state while condenser changes state as well):
High Level Chiller Medium Level Chiller Low Level Chiller
Continued…
UREA PLANT
Urea is manufactured by direct synthesis of gaseous CO2 and liquid NH3. The process consists of following operations:
Urea Synthesis High Pressure Recovery Medium Pressure Recovery Low pressure Recovery Urea Concentration Waste Water Treatment Urea Prilling
