Research and Application of Hydrodesulfurization Technology in Coke Oven Gas Project
Aiming at the main problems and situation of coke oven gas recovery in China are analyzed,and the composition characteristics of coke oven gas and the method and principle of hydrodesulfurization are studied and summarized.Fe-mo hydrogenation catalyst is suitable for the presence of CO environment,organic sulfur,especially mercaptan,thiophene and other organic sulfur conversion rate is high and the reaction is mild,at a certain temperature,can be all organic sulfur hydrogenation into easily removed H2S,and then series ZnO desulfurizer removed,this method is a very effective method for the removal of organic sulfide,this paper combined with a project example.This paper introduces the application of hydrodesulfurization technology in the actual project of producing LNG from coke oven gas,and optimizes the process,solves the problem of flying temperature in the production process,and obtains good results.
