Ammonia oil separator in urea plant

The manufacturing process of nitrogenous fertilizer are
highly energy intensive. About 80 % of the manufacturing
cost of urea accounts for the feed stocks costs. Substantial
savings can be achieved by incorporating even a minor
modification . In this article , efforts are made to highlight
the benefits achieved with pressurised operation of
Ammonia-oil separator of High Pressure (HP) ammonia
pumps in Urea plant.. Complete recovery of ammonia from
HP ammonia pump packing result in saving of 90 kg/hr of
ammonia and 950 kg/hr of LP steam in urea plant which is
equivalent to saving of Rs 45 lakhs per annum.
