Abstract
A method of stripping volatile contaminants from ammonia plant process condensate and recovering a stripped process condensate and using same as a high quality makeup water for operating units within the ammonia process which comprises: (a) feeding ammonia plant process condensate to the upper stages of an evaporative stripping tower equipped with a collection basin, and (b) allowing said condensate to flow downwardly against an upward flow of air, and (c) operating the evaporative stripping tower in at least a once-through manner, and (d) collecting the stripped process condensate in the evaporative tower collection basin, and (e) recovering the stripped process condensate from the evaporative tower basin, and (f) reusing this stripped process condensate as water makeup for other process operating units.
