摘要： The present invention discloses a process for the synthesis of urea wherein, in a process for the synthesis of urea in combination with a process for the synthesis of ammonia, the necessity of cooling the circulating gas of the process for the synthesis of ammonia for separating ammonia for use in the synthesis of urea is eliminated, thereby not only avoiding the heat loss due to the cooling but also rendering unnecessary the facilities for the cooling. Thus, the process is made simple and economical.

摘要： UREA RECYCLE PROCESS IN WHICH WATER CONTENT OF RECYCLED NH3 AND CO2 IS REDUCED AND CONVERSION IN UREA REACTOR IS INCREASED. MAJOR PORTION OF THE HEAT OF REACTION GENERATED FROM THE CONDENSATION OF THE RECYCLED NH3 AND CO2 GASES TO FORM AN AQUEOUS AMMONIUM CARBANATE SOLUTION IS RECOVERED IN HEAT EXCHANGE WITH REACTOR FEED STREAMS, TO PRODUCE STEAM IN A REACTOR COIL. HEAT GENERATED IN A UREA SYNTHESIS REACTOR IS USED IN ONE OR MORE RELATED OPERATING UNITS INCLUDING AMMONIUM CARBAMATE DECOMPOSERS, THUS PROVIDING AN EFFICIENT PROCESS HEAT BALANCE.
