Separated gas flow comes out of the first reaction zone operated at high temperature and enters the second zone operated at lower temperature. Liquid stream containing ammonia and/or ammonium carbonate passes from the second zone into the first one, said gas flow preferably representing at least 5 wt % of the liquid stream coming out of the first zone and directed into following separation stages. Ratio of urea to the sum of urea and carbamate in stream leaving reaction stage is maintained above 70%.
