Abstract

Aq. liquors contg. phenols are treated by adding caustic alkali, removing volatile material by a partial vaporisation with washing, distilling the liquid with caustic alkali bubble washing of the vapour, then disposing of the water and the mineral salts before incineration of the organic material. Caustic is pref. added to the aq. liquors to neutrality, the caustic used is taken from the bubble washing; the alkali is pref. NaOH. The vapour from the distillation is pref. condensed and carbon treated. The residue from the distillation is pref. treated with an organic solvent then filtered to remove mineral salts; the etract then being distilled followed by incineration of the residue or alternatively mixed with tar. Mineral salts are removed before incineration thereby greatly decreasing the volume to be burnt and the intensity of heat required, and avoiding the need to purify the gaseous exit from the incinerator. Partic. for effluent from coking plants.
