Abstract

PURPOSE: To prevent the condensation of steam in the recovery of gas-oil and naphthalane in coke oven gas with an absorbent oil, by recycling a part of gas-oil distilled off from the expelling tower, and keeping the molar ratio of the gas-oil to steam in the expelling tower at a specific level.
CONSTITUTION: Gas-oil and naphthalene in coke oven gas are collected and recovered with an absorbent oil. In the above process, the molar ratio of the gas- oil to be expelled to the expelling steam in the expelling tower is maintained at ≥0.2 by recycling a part of the gas-oil distilled off from the expelling tower, and joining with the benzene-containing obsorbent oil to be fed to the expelling tower.
EFFECT: Prevention of the lowering of the naphthalene oil purity and the corrosion of the expelling tower.
