Abstract

Herein disclosed is a method of removing at least one component from a feed by subjecting the feed to high shear in the presence of carbon dioxide to produce a high shear-treated product and separating the at least one component from the high shear-treated product to produce a component-reduced product. Also disclosed is a method of removing asphaltenes from asphaltenic oil by subjecting the asphaltenic oil to a shear rate of at least 10,000 sāˆ’1 in the presence of carbon dioxide to produce a high shear-treated product and separating asphaltenes from the high shear-treated product to produce an asphaltene-reduced product oil. Systems are also provided for carrying out the methods.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit under 35 U.S.C. Ā§119(e) of U.S. Provisional Patent Application No. 61 / 262,027, filed Nov. 17, 2009, the disclosure of which is hereby incorporated herein by reference.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

[0002] Not Applicable.BACKGROUND

[0003] 1. Technical Field

[0004] The present invention relates to systems and methods for enhanced recovery and processing of heavy crude and / or bitumen. More particularly, the present invention relates to the high shear removal of asphaltenes from feeds comprising bitumen and / or heavy crude oil and the high shear separation of water and mineral solids from tailings conventionally sent to a tailings pond.

[0005] 2. Background of the Invention

[0006] Large deposits of heavy hydrocarbon sometimes referred to as bitumen are located in many countries around the world. Bitumen may be recoverable by means of secondary or tertiary recovery processes that involv...
