The feed in the previous service was 21 mt/hr of mixed amines with ammonia. A 316 stainless steel internal condenser is used in the top of this column to condense the ammonia in the overhead stream. The condensed ammonia is collected in a catch pan and further cooled in the recycle coolers before being sent to storage. In the previous service, 9 mt/hr of ammonia was recovered. Steam is used on the 316 stainless steel reboiler to provide the separation momentum. In the previous service, the bottoms flow was 12 mt/hr of mixed amines.
