ABSTRACT:
An on-site automated closed loop petroleum based hydrocarbon fluid filtration and recycling system that continuously recycles a spent petroleum based hydrocarbon fluid and simultaneously continuously dispenses the recycled petroleum based hydrocarbon fluid. The system includes a hollow and open-top fluid reservoir, a lid that selectively opens and closes the hollow and open-top fluid reservoir, inlet apparatus that inputs the spent petroleum based hydrocarbon fluid into the hollow and open-top fluid reservoir, outlet apparatus that outputs the recycled petroleum based hydrocarbon fluid from the hollow and open-top fluid reservoir, a first filtering stage that removes large particles of dirt and grease from the spent petroleum based hydrocarbon fluid passing therethrough, a second filtering stage that removes small particles of dirt and grease from the spent petroleum based hydrocarbon fluid passing therethrough, a submersible internal pump that draws in the spent petroleum based hydrocarbon fluid passing through the second filtering stage, a third filtering stage that adsorbs grease and dirt from the spent petroleum based hydrocarbon fluid passing therethrough, a fourth filtering stage that removes discoloration from the spent petroleum based hydrocarbon fluid passing therethrough.
