摘要：

针对影响7 m顶装焦炉煤气净化系统磷酸洗氨稳定的因素进行分析，通过优化吸收塔捕雾工艺、提高富液除油效果、优化换热器结构、完善贫液除渣等措施，磷酸洗氨系统稳定运行周期由3个月提高至12个月以上，磷酸耗率由2.3 kg/t降低至1.7 kg/t，为焦炉煤气脱氨净化及焦炉煤气稳定输送创造了条件。

Abstract:

Analysis is made to the factors affecting the operation of COG ammonia scrubbing by H3PO4 for 7 m top-charge battery.Measures are taken by optimizing the demisting process of ammonia absorber,improving de-oiling efficiency from rich oil,restructuring heat exchanger and improving lean liquor de-sludging,etc..After the optimization,stable operation of the ammonia scrubbing system by H3PO4 can be extended from 3 months to 12 months,and the H3PO4 consumption rate can be reduced from 2.3 kg/t to 1.7 kg/t,which plays a decisive role in COG purification and stable delivery.

Key words: COG, Ammonia scrubbing by H3PO4, Oil content in mother liquor, H3PO4 consumption rate
