AQUEOUS DISPERSION OF AN OIL SOLUBLE DEMULSIFIER FOR BREAKING CRUDE OIL EMULSIONS

摘要

Demulsification of a water-in-oil, especially a water-in-crude oil, emulsion is effected by contacting it with an aqueous composition having at least one oil-soluble demulsifier and at least one water-soluble surfactant. These aqueous formulations are advantageous over conventional organic formulations of demulsifiers, as the need for toxic and/or flammable/combustible organic solvents is eliminated.
