Oil Extraction Method and Composition For Use In The Method

Abstract

A composition is disclosed for aiding extraction of an emulsified oil from an oil and water emulsion. The composition includes silicon containing particles at a level of 0.1 wt. % to 30 wt. %; an emulsifying agent at a level of 1 wt. % to 30 wt. %; and water at a level of 40 wt. % to 99 wt. %. A method of extracting oil from an oil and water emulsion in a material is also disclosed. The method includes the steps of (a) dispersing silicon containing particles into the material using a mechanical blending device; and (b) separating the oil from the material. A method of extracting oil from an oil and water emulsion in a material is also disclosed. The method includes the steps of (a) providing a dispersion of silicon containing particles in water; (b) metering the dispersion into the material; and (c) separating the oil from the material.
