The present ammonia plant is being replaced by a new and modern unit with a higher production rate of 900T/ day. Major portion of the ammonia will be converted into HNO3 which on digesting with rock phosphate will yield Ca (NO3). This is separated from the mother liquor solution on cooling down as crystals and finally converted to NH4 NO3 by passing through its melted solution, a stream of gaseous NE3 & Co2 and thus precipitating down CaCO3 as a by-product & part of it used as a filler. The acidic nitro phosphate solution still containing some dissolved Ca(No3)2 is neutralized with ammonia and finally converted and prilled as NP.
