Abstract
A hydrolysis reactor for removal of urea, ammonia and carbon dioxide from a liquid phase comprising urea in aqueous solution advantageously comprises a dividing baffle extending horizontally at a preset height in the reactor in which it defines a first and a second respectively lower and upper reaction space, means of collection and extraction from the reactor of a first portion of a gaseous phase comprising high pressure and temperature steam, previously fed into the first reaction space and means for feeding a second portion of the gaseous phase comprising high pressure and temperature steam to the second reaction space.
