This invention describes a solution to separate pure ammonia from the recirculation section by introducing a washing column (packed bed column) with pure ammonia as reflux. In this way high temperatures can be applied in the bottom to remove as much as possible unconverted ammonium carbamate while in the top pure ammonia will be recycled.
