ABSTRACT:
An integrated ammonia urea process where the reaction of carbon dioxide and ammonia is in a urea reactor having a condensing section, a reaction section having more than one stage and a stripping section. The raw ammonia synthesis gas containing carbon dioxide is introduced into the stripping section of the urea reactor at a pressure selected within the range of 2000 and 3500 psig. The stripping effluent removed from the stripping section comprises the raw ammonia synthesis gas, carbon dioxide and ammonia which is introduced into a state of the reaction section.
