Abstract

Process for the production of urea starting from carbon dioxide and ammonia, by synthesis, characterized by the fact that the ammonium carbamate present in the reaction products leaving the autoclave, is decomposed in ammonia and carbon dioxide, under pressure, supplying heat and simultaneously adding ammonia to said reaction products.
