ABSTRACT:
The invention relates to a process for treating purge gas including carbon dioxide, water vapor, organics and ammonia. In accordance with the invention, the purge gas is scrubbed with water to absorb ammonia and water is added to the scrubbed purge gas in an amount in excess of the amount required to dissolve the maximum amount of ammonium carbonate which can be formed from any ammonia and carbon dioxide present in the purge gas. The purge gas is subsequently cooled to condense the remaining organics and water and to provide a purge gas suitable for venting.
