DEVICE FOR PURIFICATION OF COKE OVEN GAS AND METHOD FOR PURIFICATION OF COKE OVEN GAS USING THE SAME

摘要

The present invention is an absorption tower in which the _{H 2S absorption liquid absorbs H 2} S from the coke oven gas; A regeneration tower connected to the absorption tower _{to remove H 2S from the H 2} S absorption liquid; And it provides a coke oven gas purification apparatus including a filter for removing naphthalene contained in _{the H 2} S absorption liquid discharged from the absorption tower, and a coke oven gas purification method using the same. According to the present invention, _{naphthalene is removed from the H 2} S absorbent liquid through the filter to prevent clogging of the heat exchanger and the H _{2 S absorbent liquid tank.}
