Abstract
PURPOSE: To remove and recover tar or the like contained in a gas liquor from a coke oven by a closed system, while effectively utilizing the existing equipment, by extracting and washing the gas liquor with crude benzene and treating the washed product with precipitated breeze from a quenching tower.
CONSTITUTION: A tar-containing gas liquor obtained by washing and cooling gas produced in a coke oven gas production equipment is separated into tar and a gas liquor in a tar decanter. A gas liquor 7 obtained by passing the separated gas liquor through a coke filter is fed to the upper part of an extracting column 1. Crude benzene 8 obtained in an equipment for recovering benzene of the like contained in the coke oven gas is introduced to the lower part of the extracting column, in an quantity providing a definite ratio to the quantity of the gas liquor introduced from the top of the extracting column. Then, the gas liquor in a gas liquor tank 4 is fed to a filter 6. The filter 6 is packed with precipitated breeze from the quenching tower. The packed breeze adsorbs, filters and removes an emulsion or suspended matter consisting mainly of light oils in the gas liquor.
