摘要:

由于氨回收系统的高压洗氨泵和低压洗氨泵故障频繁,导致高压弛放气和低压不凝气因氨含量超标而放空。针对存在的问题,从中压锅炉给水泵出口管道引锅炉水至高压洗氨系统和低压洗氨系统,洗氨后的高压弛放气和低压不凝气中氨含量完全满足设计指标要求,取得了较好的经济效益和环保效益。

Abstract:

The frequent malfunction of high pressure ammonia washing pump and low pressure ammonia washing pump, which are used in ammonia recovery unit, leads to problem of high level of ammonia content in high pressure purge gas and low pressure non-condensable gas which have to be vented. In connection with the existing problem, boiler water is led out from the outlet pipe of medium-pressure boiler feed water pump to high pressure ammonia washing system and low pressure ammonia washing system, the ammonia content of high pressure purge gas and low pressure non-condensable gas from ammonia washing system fully meets the design specifications, better economic and environmental benefits are obtained.
