Abstract
A method and composition for isolating a paraffinic hydrocarbon layer from a sludge comprising paraffinic hydrocarbons, water, and solids. The method includes contacting the sludge with isopropylamine dodecylbenzene sulfonate, a cutter stock, and water. The isopropylamine dodecylbenzene sulfonate comprises a concentration of at least 1500 ppm. The ratio of sludge:cutter:water is at least 4:2:1. The method also includes determining if the sludge has separated into a three phase separation comprising a paraffinic hydrocarbon layer, a water layer, and a layer of settled solids.
