Abstract

See full text

An ammonia-producing system comprises a reactor that catalytically converts nitrogen and hydrogen feed gases to ammonia to form a reaction mixture of the ammonia, unreacted nitrogen gas, and unreacted hydrogen gas. A feed system feeds the nitrogen and hydrogen gases to the reactor at a reaction pressure of from about 9 to about 100 atmospheres. A reactor control system controls the temperature during conversion of the nitrogen and hydrogen to ammonia by maintaining a reaction temperature of from about 330° C. to about 550° C. An absorbent selectively absorbs at least a portion of the ammonia from the reaction mixture, and an absorbent control system controls one or both of a temperature and pressure at the absorbent during selective absorption of the ammonia from the reaction mixture. A recycle line downstream of the absorbent recycles the unreacted nitrogen and unreacted hydrogen to the reactor.
