Single addition organic-inorganic blend emulsion breaking compositions suitable for breaking oil-in-water emulsions are prepared which consist essentially of an aqueous solution of a water soluble acidic aluminum salt and a water soluble quaternized dehydration condensation polymer of triethanolamine or acylated triethanolamine, or mixtures of triethanolamine and acylated triethanolamine, said polymer containing tertiary amino groups of which 20-100% are quaternized.

Single addition organic-inorganic blend emulsion breaking composition

A method of resolving water-in-oil emulsions resulting from the organic solvent extraction of uranium from aqueous leach liquors which comprises treating said emulsions with at least 20 parts per million of a water-soluble acrylamide copolymer which contains from 5 - 50% by weight of a lower alkyl substituted tertiary aminoethyl methacrylate and quaternary ammonium salts thereof.

Emulsion breaking

A method for dewatering tar-water mixtures obtained from the coking of coal is disclosed. The method involves adding to the tar from 150 to 3,000 ppm of a di-tri butyl ethoxylated phenol compound dissolved in water, heating the tar-water mixture, and then agitating it to allow contact with the chemical additive. This is followed by allowing the mixture to settle forming an aqueous upper phase and a lower dewatering tar phase.
