摘　　要：对广州石化乙烯装置CO2含量高的问题进行研究分析,确认裂解原料石脑油钠含量高是造成CO2含量高的原因。同时石脑油钠含量高对乙烯装置可造成裂解炉炉管运行周期短、碱洗系统CO2出现穿透等问题,提出了控制原料质量、对裂解炉管烧焦期间增加水洗浸泡及碱洗塔优化等调整措施,保证了乙烯装置的安全稳定运行。This article analyzes the causes of high CO2 content in the ethylene plant of SINOPEC Guangzhou Company.It is concluded that the high sodium content of the naphtha used as cracking raw material is the reason for the high CO2 content.At the same time,the high sodium content of naphtha may cause problems such as short operation cycle of furnace tube and CO2 penetration of caustic wash system.Some adjustment measures are proposed including the quality control of raw materials,the scrubbing and soaking during the coke burning of furnace tubes and the optimization of caustic wash tower,so as to ensure the safe and stable operation of the ethylene plant.
