Abstract: A cleaning process for industrial rags to remove petroleum-based solvents in an environmentally safe manner comprises a series of steps. The industrial rags are initially subjected to high speed forces in a rotary drum to physically extract liquid solvent. The high speed extraction step is conducted while preferably maintaining a temperature within the drum of below the flash point of the petroleum-based solvent. Next, the rags are tumbled while being subjected to intermittent forced blasts of cold air and hot air to vaporize solvent remaining in the rags. The vapors are routed from the drum and condensed. The extracted liquid solvent and condensed solvent vapors are both routed to a waste solvent collection line. The industrial rags are finally cleaned with a dry cleaning solvent and dried to produce clean rags suitable for reuse.

Abstract: An underground storage tank system has an internal retained capacity area for receiving excess liquid from a filling operation. The storage tank system comprises a rigid storage tank, a fill pipe, a vapor recovery tube, a vent line, a dispensing line, and a trapped vapor release valve. A vapor recovery extension tube and vent extension line each extend into the storage tank. The uppermost of the lower end of the vapor recovery extension tube and lower end of the vent extension line within the storage tank defines a horizontal plane above which is an internal retained capacity area. The trapped vapor release valve is closed during a filling operation so that eventually a build up of pressure occurs within the retained capacity area to prevent further flow of liquid to the retained capacity area of the tank. Opening of the trapped vapor release valve relieves the pressure in the retained capacity area thereby allowing excess liquid in the fill pipe and delivery hose to drain into the storage tank.
