Abstract: Application of Rectisol wash process in the Yitai 160000 t/a coal to liquids demonstration project is introduced. The problems of installation and operation, and the improvement measures are presented. Operation results show that good improvement is achieved, methanol consumption is controlled at 1.13kg/m3, water content is reduced to less than 0.5%, shift gas instead of low pressure steam saves steam consumption by 60680 t/a. The characteristics of the technological process is analyzed. Application of the Rectisol wash process in indirect coal liquefaction demonstration plant is successful. It is an advanced process with high degree of purification and stable quality of purified gas.

Key words: coal to liquids, Rectisol, coal gas purification, sour gas removal
