Abstract
A process for manufacturing ammonium salts using a reactor which includes a first tubular reaction chamber having at least one acid feed and at least on ammonia feed which are arranged in a first up-stream part of the reactor. At least one second ammonia feed is introduced into a second part of the reactor which is arranged as an extension of the first and which includes, in a flow direction, a convergent segment, a cylindrical tube and a divergent segment. The second ammonia feed communicates with the second part in the vicinity of the convergent segment and the processes is controlled to obtain basic vapors at an outlet of the reactor.
