摘　　要：鼓冷工段横管冷却器冷却焦炉煤气下来的带轻质焦油的冷凝液，用于煤气直冷塔在冷却煤气同时进行洗萘，代替粗苯工段的富油冼萘工艺，为净化焦炉煤气中的萘提供了可靠的依据。The condensate with light-tar got in cooling the coke-oven gas in horizontal-tube cooler in blasting-cooling section can be used to wash naphthalene in the same time when gas is cooled in the gas direct-cooling tower. This can replace the rich-oil naphthalene-washing process in benzol section and offer the reliable reference for removing the naphthalene in coke-oven gas.
