An apparatus for the decomposition of non-converted ammonium carbamate in urea solutions in a urea synthesis process

摘要

An apparatus used for the decomposition of non-converted ammonium carbamate in a supplied urea solution in a urea stripping synthesis section. The apparatus comprises a number of heat exchanger tubes between a top chamber and a bottom chamber, a liquid distributor mounted on each heat exchanger tube and a gas/ liquid separator together with a perforated basket at the centre of the top chamber.
