The process was based on license from Stemicarbon, Holland, while detailed Engineering was made by Uhde, Germany.
The plant was designed to produce 229.4 MTPD of P2O5 or 1,015 MTPD of Nitro Phosphate (NP) having 22.6% P2O5 with 300 on stream days/annum. The plant could not produce NP product at its rated capacity both in terms of designed quality as well as quantity at the time of guarantees; Uhde was made to undertake modifications on the plant, which they performed through addition of 2-lines of Crystallizers making total six lines. Similarly 2 centrifuges were added to 4 existing ones and additional refrigeration capacity was provided. However, even after the modifications desired product quality could not be achieved. The plant consumes much higher energy level as compared with design.
In view of the fact that plant could not produce 22.6% P2O5, the specs were revised to 20% P2O5 and 22% Nitrogen (originally 22.6% each of Nitrogen and P2O5).
