PROCESS FOR THE UREA SYNTHESIS FROM AMMONIA AND CARBON DIOXIDE AND APPARATUS FOR CARRYING OUT THE PROCESS

A urea synthesis process starting from ammonia and carbon dioxide carried out under a pressure of 120x10 2 to 400x10 2 KPa and a temperature of 140 to 215° C., in which the reaction takes place in a reactor in which gaseous CO 2 is fed in the bottom of the reactor while liquid ammonia and the recycl...

Zusammenfassung:	A urea synthesis process starting from ammonia and carbon dioxide carried out under a pressure of 120x10 2 to 400x10 2 KPa and a temperature of 140 to 215° C., in which the reaction takes place in a reactor in which gaseous CO 2 is fed in the bottom of the reactor while liquid ammonia and the recycled ammonium carbamate aqueous solution are fed from the top of the reactor, and going downward the reactor, they meet in countercurrent the rising gaseous CO 2.
