撬式过滤组合在低温甲醇洗工艺中的应用探讨

Application Discussion of Skidded Filter Combination in Rectisol Process

气体净化中的低温甲醇洗工艺是近年来脱除酸性气体普遍采用的一种净化工艺。该工艺以其技术成熟、溶剂廉价易得、净化度高、选择性好等特性,被广泛应用于合成氨、合成醇类等行业。甲醇循环液的纯净度是保证低温甲醇洗装置的长周期稳定运行的重要前提。撬式过滤组合被应用于低温甲醇洗工艺,能有效确保甲醇液的洁净度。

The rectisol process in gas purification is a common purification process used in the recent years for the removal of acidic gases. The process is used widely in the synthesis of ammonia, alcohol and other industries due to the fact that the technology is mature and has many good characteristics such as the high purification rate, good selectivity, easily acquired and cheap solvent. The purity of the methanol circulating fluid is an important factor for a stable and long period operation of the rectisol equipment. In this paper, Skidded Filter combination can be used in rectisol process to effectively ensure the purity of the methanol.
