Patent ID: 10792587

Abstract:
A system and method for improving hydrocarbon fuel, such as diesel, particularly after contamination in underground storage tanks with other fuels such as gasoline, etc. High-gravity hydrocarbons present in diesel and/or water are removed via aeration of the (out-of-specification/contaminated) diesel. The removal of unwanted hydrocarbons and other contaminants can be accomplished in a number of fashions, including pumped air, exposure of the line, drawing of air into the line, etc. After removal from the diesel line, high-gravity hydrocarbons can be isolated and recycled or re-used, for instance to power the system. Following the conditioning, the diesel may be returned into specification for dispensation at a commercial or retail fuel center for use in vehicles and diesel combustion engines. The system and process may be portable and/or conducted locally at the site of an underground storage tank.
