| Abstract: | The paper analyzes the problems,excessive temperature of catalysis bed,high steam consumption,quantities of process condensate etc.,frequently occurred in CO shift system with high water to gas ratio process in Shell gas based methanol plant.Some measures to solve it were adopted,but the effect was limited.So the low water/gas CO shift process was presented.The paper introduces its design concept and revamp detail.The problems are solved effectively after revamping and the process converting is completed. |

| Keywords: | Shell gas shift sulfur-tolerant catalyst high water to gas ratio low water to gas ratio converting |
