An improved process for the removal of urea, ammonia, and carbon dioxide from process condensate derived from coupled urea and ammonia syntheses by hydrolysis of urea and desorption of ammonia and carbon dioxide. Process condensate poor with respect to ammonia is treated at a pressure of between about 15 and 42 bar and a temperature of between about 200.degree. C. and 320.degree. C. in a reaction column with steam to form a gas mixture containing ammonia, carbon dioxide, and water vapor, and an aqueous liquid virtually free of urea, ammonia, and carbon dioxide.
