Discussion on treatment technology of ammonia-containing acid gas in coal chemical acid water stripping unit
The current situation and main problems of the ammonia-containing acid gas treatment process in the domestic coal chemical acid water stripping unit were introduced,and the necessity of optimizing the ammonia-containing acid gas treatment process was explained.Two processes were introduced:ammonia extraction from the middle section of acid water stripper,and ammonia-containing acid gas co-production of ammonium bicarbonate.They were compared in detail from five aspects:utility consumption,product scale,economic benefits,product usage,and device advantages and disadvantages.Finally,it was determined that for the coal chemical industry,the ammonia-containing acid gas co-production of ammonium bicarbonate process had more advantages.
