Abstract: This paper introduces the requirements of emission index of dust removal in CDQ (coke dry quenching) environment, the source and composition of dust removal flue gas in CDQ environment and the treatment scheme for reaching the standard, the advantages and disadvantages of moving bed activated carbon process, fixed bed activated carbon process and calcium oxide desulfurization process. It also gives the reason why coking plant chose moving bed activated carbon process.

Keywords: CDQ;SO2;process comparison; investment; running costs; raw materials and products
