Abstract: The invention relates to a process for the preparation of urea from ammonia and carbon dioxide, which preparation takes places wholy or partly with the application of a synthesis reactor, a condenser, a scrubber and a stripper, wherein an outlet of the stripper, through which a gas stream is discharged during operation, is functionally connected to the inlet of the condenser and to the inlet of the reactor and wherein an outlet of the condenser is functionally connected to an inlet of the scrubber and wherein the obtained reaction mixture is stripped in the stripper in countercurrent with one of the starting materials, wherein the gas stream coming from the top of the submerged condenser is subjected to an extra washing step before this gas stream is supplied to the high-pressure scrubber. The submerged condenser operating as such may he for example a submerged condenser of horizontal or vertical design of a falling-film high-pressure carbamate condenser transformed into a submerged condenser.
