Abstract
AbstractThe following methods of disposal and treatment of phenolic liquors from coke oven plants are studied: direct use on froth flotation media in coal washing plant. The coal absorbs 60% of the phenols present, but only half the normal output can be used in this way. chemical oxidation of the phenols by ozone. This is satisfactory for dilute liquors (100 p.p.m. of phenols) but is too costly for spent ammoniacal liquors. biological oxidation. The activated sludge process is satisfactory but somewhat expensive. An enclosed percolating filter containing coke activated with soil organisms gave promising results. extraction of phenols. The use of light creosote oil in a rotating disc extractor gave promising results. For liquors rich in phenols, the procedure recommended is method (4) followed by methods (3) or (1) and then method (2) if desirable. Final effluents with 10–50 p.p.m. of phenols can be obtained.
