ABSTRACT:
This invention concerns a process for cooling the crude coke oven gas drawn from a gas collecting main at a gas temperature of below 20.degree. C. after separating a collecting main flushing liquid fed to a tar separator. To prevent deposists of naphthalene on the cooling tubes of a precooler, the invention provides that the crude coke oven gas is treated before the precooler with tar or a tar-water mixture withdrawn from the tar separator. This effects a partial evaporation of the more volatile components, and the remaining tar or tar-water mixture is again withdrawn before the precooler. A flushing liquid from the edge zone of the tar separator that has definite proportions of low-solids and lighter tar is used in particular and it is fed in parallel with the cooling crude gas in the precooler.
