Abstract (English, WO 1998045211 A1)
Ammonia production is increased in an ammonia plant having a primary reformer, a secondary reformer and an air compressor, where the primary reformer and/or the air compressor is operating at its maximum capacity, without investing to expand the capacity of either. A portion of the feed can bypass the primary reformer and enter the secondary reformer directly. Oxygen and nitrogen streams are added separately and independently to form an ammonia synthesis feed gas. Methane concentration in the outlet stream from the secondary reformer is controlled by manipulating the oxygen stream. Nitrogen concentration or a H2:N2 ratio in the ammonia converter feed gas is controlled by manipulating the nitrogen stream.
