Optimization Of Nitrogen Wash Column Operation

Nitrogen wash column is being used in the production of ammonia process. It is usually the purification step of H2 in the ammonia synthesis. The liquid nitrogen wash column has the function to remove residual impurities like CO, Argon and CH4 from a crude hydrogen stream and to establish a stoichiom...
