The CO2 removal system is one of the major energy consuming section in the ammonia units and very often a bottleneck to increase the NH3 production. This paper describes well proven GV technologies that can be applied to CO2 Strippers in the CO2 removal section of ammonia plants to save energy and boost ammonia production. Case histories are discussed to illustrate the results achieved in several revamped units.
