Benefits of technology

[0005]It is also an object of the invention to have a very high through-put and yet take up minimal space so that capital costs and ongoing costs may be substantially reduced.

Problems solved by technology

The physical separation of oil, bitumen and kerogen, from sand or rock has been an ongoing problem with all the deposits throughout the world.
All of these processes have trouble dealing with the heavy fraction of the oil which contains the asphaltenes, as well, the colloids and new compounds formed make the remediation and disposal of their tailings very expensive.
Also by the very nature of current practices there are exceedingly significant losses in product such that only with extremely high capital investments in order to achieve economies of size or by high crude prices can the operations be made economically viable.
Other ongoing problems are the high use of both water and propane to the point that the provincial government is considering restrictions on their use.

Embodiment Construction

[0018]The composition of the Athabasca Tar Sands is such that the individual grains of silica (sand) are surrounded by a thin layer of nascent water containing ionic calcium.

[0019]According to one embodiment of the invention an electrochemical process is provided for separating oil or bitumen from sand or rock leaving clean sand and colloids and clean oil / bitumen. The process utilizes a solution of hydrogen peroxide and water held between two large carbon electrodes. A 100 volt DC current is then applied to the two electrodes. At this time it will be noted that the ammeter shows a current draw of one to two amps. The bitumen sand can be placed anywhere in the container between the two electrodes, but to facilitate the reaction it is placed on a fine plastic screen such that as the sand is released from the oil it automatically falls away from the tar sand and because of entrained gases the liquid hydrocarbons will then automatically float to the surface.

Abstract

The method relates generally to an improved method for the recovery of hydro-carbons from bitumen / oil deposits such as oil sands, tar sands, oil shales and conventional oil deposits. The method charges the silicon particles thus repulsing the oil, at the same time the hydrogen peroxide selectively reacts with metals, metal compounds and the charged silicon particles giving off energy and oxygen which then floats the oil to the surface, By reacting with the organo-metallic compounds it destroys them, thus freeing the oil from transition metals and producing a much cleaner product.

Description

FIELD OF THE INVENTION [0001]This invention relates generally to a method of separating hydrocarbons from another material and in particular to a process for recovering hydrocarbons from oil type deposits, such as bitumen / oil sands, oil shales, and conventional oil deposits.BACKGROUND OF THE INVENTION [0002]The physical separation of oil, bitumen and kerogen, from sand or rock has been an ongoing problem with all the deposits throughout the world. Current methods are usually pyrolysis, hot water and sodium hydroxide, or dilution with solvents such as xylene or toluene. All of these processes have trouble dealing with the heavy fraction of the oil which contains the asphaltenes, as well, the colloids and new compounds formed make the remediation and disposal of their tailings very expensive. Also by the very nature of current practices there are exceedingly significant losses in product such that only with extremely high capital investments in order to achieve economies of size or by...
