Abstract

PURPOSE: A stable treatment method for gas liquor in which the lowering of thermal transmission efficiency in cooler can be restored.
CONSTITUTION: The gas liquor 1 from coke oven is introduced into the stripper 9 to strip ammonia present, and the bottom liquor of the stripper 9 is cooled by the coolers 26 and 27 and then treated with activated sludge. In this method, the lowering of the thermal transmission efficiency of the coolers 26 and 27 due to the adhesion and growth of scale can be restored by cleaning the scale grown with the lapse of time with a 1W10wt% strong alkali aqueous solution kept at 50W100°C.
