Abstract

Process for the preparation of urea from ammonia vapors containing carbon dioxide and water occasionally, for example originating from vapors in the production of melamine based on urea, which process comprises introducing said ammonia vapors in a mixer device apparatus absorber, where they are condensed together with ammoniacal vapors of glue containing water, coming from the reaction column of the synthesis of urea and recycled with a regulated circulation speed in terms of the proportions of NH3/H2O and CO2/H2O and pumping to said reaction column the solution thus obtained in the aforementioned mixer-absorber.
