The plant had a production capacity of 570,000 tons per annum (TPA) and an initial construction cost of US$303 million. [12] The plant was supplied by Haldor Topsoe and was commissioned in 1982 after an additional investment of US$15 million. [12] As of 2024, FFC-I has a capacity to produce 403,000 TPA of ammonia and 695,000 TPA of urea. [13]
Auxiliary Boiler – The Ammonia and Urea plants are supplemented with an auxiliary boiler of 60 MT/h steam capacity at 75 kg/cm 2 pressure and 480 °C. Purge Gas Recovery Unit (PGRU) – The productivity of the Ammonia plant was increased by installing a PGRU in May 1984 of 4,800 Nm 3 /h capacity.
Specifically, highly alkaline soils (pH~8.2 or higher) have proven to increase urea hydrolysis. One study has shown complete hydrolysis of urea within two days of application on such soils. In acidic soils (pH 5.2) the urea took twice as long to hydrolyze. [7] Surface residues, such as thatch and plant stubble exhibit increased urease activity.
