Abstract

PURPOSE: A method of treating gas liquor in which treatment is stably made by lessening pressure loss in stripper.
CONSTITUTION: In a method of stripping ammonia present in the gas liquor 1 introduced into the stripper 9 from coke oven with steam or steam-containing gas, pressure loss in the stripper 9 can be reduced by cleaning scale adhered to and grown on the inside of the stripper 9 with the lapse of time with a 1W10wt% strong alkali aqueous solution of sodium hydroxide, potassium hydroxide, etc., kept at 50W100°C. The strong alkali aqueous solution can be recycled through the tank 32, and conduits 34 and 35.
