Claim:
1. An equipment, comprising: a distillation unit comprising a hydrophobic microporous membrane configured to operate at a temperature of 50 to 250° C. and at a pressure of 50 KPa to 20 MPa absolute; a feeding line connecting the distillation unit to a urea synthesis reactor; and a heating unit, wherein the feeding line feeds to the distillation unit an aqueous solution, which is a reaction effluent from the urea synthesis reactor comprising from 20 to 70% by weight of ammonia, from 10 to 60% by weight of carbon dioxide, from 10 to 70% by weight of water, and optionally urea; the distillation unit distils the aqueous solution and forms a residual aqueous solution and a permeated gaseous stream comprising ammonia carbon dioxide, and water; the hydrophobic microporous membrane contemporaneously recovers ammonia and carbon dioxide from the aqueous solution; and the heating units heats the aqueous solution.
