Benefits of technology

[0008]In one aspect, the invention may comprise a process for removing heavy oil or bitumen from oil sands and reducing the density of the heavy oil or bitumen, comprising the steps of contacting the oil sands with an aqueous emulsion of a monocyc

Problems solved by technology

This conventional hot water technique is energy intensive in part because of the elevated temperature of the initial hot water.
Additionally, the process produces an environmental issue in the form of the tailings byproduct which comprises a mixture of water, sand, silt and fine clay particles.
However, the leftover muddy liquid,

Example

[0034]The present invention provides for a process and composition for separating heavy oil and bitumen from solid particulate matter. Additionally, a plant for implementing the process as well as the recovered oil product are described. When describing the present invention, all terms not defined herein have their common art-recognized meanings.

[0035]The present invention is described herein with reference to cleaning heavy oil or bitumen from oil sands or tar sands. The invention may equally be applicable to removing hydrocarbons from any solid particulate matter and may be useful, for example, in cleaning oil-contaminated soil.

[0036]As used herein, an “emulsion” refers to a mixture of two liquids, where droplets of a first liquid are dispersed in a second liquid where it does not dissolve. The particles or droplets may be on a micron scale, or smaller. The dispersed liquid is said to form the disperse phase, while the other liquid is said to form the continuous phase.

Abstract

A process and composition for removing heavy oil and bitumen from oil sands is disclosed. The composition comprises an emulsion of d-limonene and water, with an anionic surfactant as an emulsifying agent. The emulsion is contacted with an oil sand slurry until the aqueous and hydrocarbon phases separate. The process may take place at temperatures less than about 80° C.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority benefit of U.S. Provisional Patent Application No. 60 / 511,315 filed Oct. 16, 2003, the contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a composition and a process for removing hydrocarbons from solid particulate matter. In particular, the present invention relates to a composition and process for separating heavy oil or bitumen from sand. The present invention also relates to a plant where the process may be implemented and the light oil product which is recovered.BACKGROUND OF THE INVENTION[0003]Considerable oil reserves around the world are locked in the form of oil sands, also called tar or bitumen sands. Particularly large deposits are known to exist in the Athabasca and Cold Lake regions of Alberta and smaller deposits are found in many areas in the United States including Utah. Oil sands are typically surface mined and the contai...
