摘要
对乙烯装置酸性气体的乙醇胺 碱洗联合脱除工艺存在的运行不稳 ,运行周期短 ,胺耗碱耗高等问题结合实际运行情况进行了分析 ,对我国大型乙烯装置该系统实施的不同改造方案进行了比较 ,提出了将乙醇胺 碱洗联合脱除酸性气工艺改为碱洗脱除酸性气工艺更具借鉴意义 ,可供同类装置改造时参考。
Problems, such as unstable running, short running cycle and high consumption of amine and caustic, etc., appeared in the acid gas removal process with alcohol amine succeeded by caustic wash in ethylene plant were analyzed. Through comparison of different technical transform schemes practised in the revamps of domestic large scale ethylene plants, it is proposed to adopt caustic wash alone for replacing the existed alcohol amine/caustic removal process.
