摘要
在生产过程中,气分装置原料液态烃中的总硫逐渐升高,将丙烯精制系统的脱水塔T-502B改为脱硫剂,但精制后丙烯中的CO与CO2含量却逐渐升高,通过调整操作流程和带固碱塔等措施降低了其含量。
The total sulfur rises in liquid hydrocarbon of gas separation equipment. T-502B was modified to desulfurizer of refining propylene system. But the content of CO and CO2 rises in refining propylene. Adjusting operation flow and taking a solid caustic soda tower to reduce the content.
