ABSTRACT:
In a process for the production of urea from ammonia and carbon dioxide by feeding ammonia and carbon dioxide into a reactor, reacting the ammonia and carbon dioxide so as to produce an effluent aqueous solution of urea contaminated with ammonium carbamate, stripping the ammonium carbamate from the said solution in the presence of a stripping agent selected from ammonia and carbondioxide so as to produce an aqueous solution of urea substantially free from ammonium carbamate and a vapor phase of ammonia and carbon dioxide, and condensing ammonia and carbon dioxide to form a solution of carbamate for recycle into the reactor, and feeding ammonium carbamate to the reactor by entraining it in a stream of ammonia fed to the reactor through an ejector.
