Effect of operation of ammonia plants on the performance of heavy water plants (Paper No. 2.7)

Heavy Water Plant, Hazira has two streams and each stream is designed to process 48 MT/hr of synthesis gas to produce the rated quantity of heavy water. However in actual practice, it is observed that actual gas composition is different from the above due to various reasons. This article describes effects of various parameters of ammonia plant on the functioning of heavy water plants, such as concentration of D/D+H in synthesis gas, concentration of hydrogen in synthesis gas, concentration of inerts in synthesis gas, pressure of synthesis gas, on stream days of ammonia plant, and concentration of impurities like CO/CO2 in synthesis gas.
