ABSTRACT:
In the synthesis of ammonia, a process is disclosed for treating the gases flowing from the synthesis reactor wherein those gases flow through a film absorber countercurrent to a cooled aqueous film to extract ammonia which is withdrawn as a strong solution from the absorber and scrubbed gases are combined for recycle with a stream of fresh feed which is then dehydrated by injecting liquid ammonia into the stream so that it rapidly expands and condenses the water vapor therein, and the dried gases are thereafter fed to the synthesis reactor.
