摘要
在介绍纤维膜脱硫技术工艺原理和特点的基础上,总结了在长岭分公司1号气体脱硫装置液化气脱硫工艺中的应用情况。在该技术的应用过程中,不断优化操作条件,液化气脱后总硫含量满足产品出厂的质量要求,脱硫碱液消耗量降低超过50%。纤维膜脱硫技术易于在原有装置上实施改造,具有较强的推广价值。
This paper introduces the process principles and characteristics of sulfur removal technology by fiber membrane.Based on this,the paper summarizes the application of such technology in the No.1 liquefied petroleum gas(LPG) sulfur removal plant in Changling Refinery.During the application of this technology,the operation conditions have been optimized continuously,the total sulfur in the LPG satisfied the quality demand of products for merchandise and the amount of alkali liquor consumption was reduced over fifty percent compared with the application of traditional technology.This sulfur removal technology by fiber membrane can be easily applied through reconstructing the original plants and it is worth popularizing.
