摘要:
A method of cleaning an industrial tank using electrical energy and critical fluid comprises the steps of transmitting electrical energy into an industrial tank to a first predetermined temperature, providing a critical fluid with a reactant or catalyst into the tank for diffusion into the contents of the tank at a predetermined pressure, transmitting electrical energy into the tank to heat the contents including the critical fluid to a second predetermined temperature to initiate reaction of a reactant in the critical fluid with a portion of the contents of the tank causing hydrocarbons and contaminants to be released for extraction as a vapor, liquid or dissolved in the critical fluid. A step of pressure cycling may be performed prior to a step of removing the contents of the tank including the hydrocarbons and contaminants. A further step includes separating the hydrocarbons, critical fluid, gases, and contaminants removed from the tank.
摘要:
The extraction of hydrocarbon fuel products such as kerogen oil and gas from a body of fixed fossil fuels such as oil shale is accomplished by applying a combination of electrical energy and critical fluids with reactants and/or catalysts down a borehole to initiate a reaction of reactants in the critical fluids with kerogen in the oil shale thereby raising the temperatures to cause kerogen oil and gas products to be extracted as a vapor, liquid or dissolved in the critical fluids. The hydrocarbon fuel products of kerogen oil or shale oil and hydrocarbon gas are removed to the ground surface by a product return line. An RF generator provides electromagnetic energy, and the critical fluids include a combination of carbon dioxide (CO2), with reactants of nitrous oxide (N2O) or oxygen (O2).

摘要:
An improved approach for cleaning and recycling materials is based on pressurized solvents including liquid propane, butane, dimethyl ether, and supercritical carbon dioxide. The approaches are particularly suitable for cleaning sorbent materials. The approach allows for recycling of the sorbent materials, the solvent and the contaminents, typically oils and the like.
