摘要：

阐述了乙烯装置废碱氧化系统的波动情况，对碱洗塔操作参数、碱洗塔各段碱液和废碱进行了取样分析。基于取样结果分析了废碱氧化系统波动的原因，判断波动主要来源于220 kt/a乙烯装置废碱中的黑色固体颗粒，并基于此提出了相应的防范措施。

Abstract:

This article elaborates on the fluctuation of spent caustic oxidation unit in ethylene plant, and analyzes the operating parameters of caustic wash tower and the sampling of caustic liquor and spent caustic in each section of the caustic wash tower. Based on the sampling results, the reasons for the fluctuation of spent caustic oxidation unit were analyzed, and it was determined that the fluctuation mainly came from the black solid particles in the spent caustic of the 220 kt/a ethylene plant. Based on this, some corresponding preventive measures were proposed.

Key words: spent caustic oxidation, bed temperature, solid particle
