Start - up and running of coke oven gas purification system of Coking Plant of Baogang;

In accordance with some existing problems of gas purification and auxiliary system in the first Project, some processes and devices have been adjusted in the second project as well as the joint between old and new systems are also considered while designing.

The present production situation, main technical improvement measure and existing problems of full negative pressure gas purification system which has been commissioned for 15 year are described in this paper.

This paper indroduced the technology development,desulphurization mechanism and the application in coal gas purification of TGF high efficiency desulphurization sorbent.
