摘要

A method of effecting the substantially adiabatic expansion of a stream of liquid ammonia at room temperature, to produce a cold liquid ammonia stream and a cold gaseous ammonia stream, each at a pressure substantially equal to atmospheric or ambient, said method characterized by the steps of: introducing into a expansion chamber a stream of liquid ammonia placed under pressure, at room temperature; communicate a high-speed rotary movement to the liquid ammonia entering the chamber, in such a way as to produce a rapid flow of circulation around the interior of the chamber, in order to obtain a rapid separation of liquid ammonia and gaseous ammonia.
