Abstract
A method and composition for isolating a paraffinic hydrocarbon layer from a sludge comprising a mixture of paraffinic hydrocarbons, water, and solids are provided. The method comprises providing a paraffinic hydrocarbon isolation composition comprising isopropylamine dodecylbenzene sulfonate, a surfactant, and a solvent; contacting the sludge with the paraffinic hydrocarbon isolation composition; and allowing the paraffinic hydrocarbon isolation composition to separate the sludge into a three phase separation comprising a paraffinic hydrocarbon layer, a water layer, and a layer of settled solids.
