Abstract

Revamping of the CO2 Removal Unit in an Ammonia production line represents one of the most economically attractive expedient to revamp old plants. The conversion of one stage low-heat (multistages flash steam ejectors) system into Giammarco-Vetrocoke (GV) two stages (dual pressure regeneration) system provides the opportunity for simultaneously improving efficiency, saving energy and increasing capacity. The first revamped plant is satisfactorily operating since one year, while a second is under advanced stage of implementation.
