Novel Approach to H_2S Removal and Ammonia Recovery from Process Condensate

摘要

This paper focuses on novel approach adopted by GNFC for selective removal of H_2S and recovery of ammonia from process condensate. Calculations indicated that by using very small quantity of tail gas containing about 80 per cent CO_2, H_2S can be selectively stripped from condensate stream. Total scheme was developed with in-house efforts and has been successfully implemented.
