低温甲醇洗的技术对比

Comparison of Technology on Rectisol Process

低温甲醇洗是目前煤化工项目普遍采用的脱硫脱碳工艺。国外主要有两家专利商的技术可供选择:德国林德公司、德国鲁奇公司。两种技术的原理相同、工艺流程类似,相应的设备选型、设备选材也有类似之处。本文参考国内两套采用水煤浆气化工艺、气量基本相同、分别采用林德、鲁奇低温甲醇洗工艺包的甲醇洗装置,在冷量提供、工艺冷损、热量等几方面进行了类比,并给出了建议。

Rectisol is nowadays a commonly used desulphuration and CO2 removal process for coal chemical projects. There are two optional foreign licensors' processes: Linde Rectisol and Lurgi Rectisol. These two processes have the same principles,similar process,similar equipment and materials.This paper makes an analogy in the aspects of cold supply,process cold loss and heat and proposes some recommendations with reference to the Rectisol units of two domestic methanol plants with coal slurry gasification process,identical gas flow,and Lurgi Rectisol Process and Linde Rectisol Process applied respectively.
