Shell煤气化净化工艺选择的探讨

Approach to the Selection of Syngas Treatment Section in Shell Coal Gasification Process

根据Shell煤气化技术的合成气的特点 ,通过对目前煤气装置中的脱硫、脱碳和变换净化工艺的比较和分析 ,同时考虑整个流程的衔接和匹配性 ,认为Shell煤气化工艺用于合成氨装置时 。

In terms of the characteristic of Shell Coal Gasification Process syngas and the linking up and matching of the whole process, A comparision and analysis are made. Among current gas purification including desulphidation, decarbonisation and CO shift process. It concludes that while Shell Coal Gasification Process is used in synthetic ammonia plant, gas purification process applying Co-Mo sulfur proof shift and one step Rectisol process is more reasonable
