Abstract:
Combined apparatus ( 1 ) for the synthesis of urea from ammonia and carbon dioxide, comprising an internal wall ( 3 ) which delimits two coaxial zones ( 4 ) inside the apparatus, operating respectively as reaction ( 4 ) and condensation ( 5 ) zones, and optionally also comprising a stripping zone and/or a scrubber integrated in the same apparatus.

Claim (Index 14):
A process for the synthesis of urea from ammonia and carbon dioxide, comprising:\n a reaction phase in which ammonia and carbon dioxide react producing an aqueous solution of urea containing unconverted ammonium carbamate and ammonia; a stripping phase of said aqueous solution which produces ammonia and CO 2  in gaseous form; and a condensation phase during which ammonia and CO 2  in gaseous form are at least partially condensed for subsequent recirculation to the reaction phase; wherein said reaction phase and said condensation phase are performed in a first zone and in a second zone of a single apparatus inside a single pressurized body, said first zone and said second zone being in communication, coaxial and arranged one around the other.
