半贫液低温甲醇洗装置运行总结及探讨

Sum-Up and Discussion of Operation of Low-Temperature Methanol Wash Unit with Semi Lean Liquid

简要介绍了低温甲醇洗工艺的原理、特点、国内外发展历程及实际运行情况。根据半贫液吸收流程与全贫液吸收流程的理论分析,提出了该工艺进一步优化的方向。

A brief introduction is made of the principle, characteristics, development history both at home and abroad and actual operation situation of low-temperature methanol wash process. Based on theoretical analysis of the absorption process of semi lean liquid and absorption process of fully lean liquid, further optimization direction of the process is suggested.
