Case 5582 Revised 11/6/79 WASTE OIL RECOVERY SYSTEM ABSTRACT OF THE DISCLOSURE Oil, used as a lubricant and coolant in an industrial process, may become contaminated by foreign materials, for example, water and solid particulate. Because of its cost, continued use of the oil is desirous but impossible if the foreign materials are not removed when the concentration of such becomes excessive. By heating the contaminated oil and adding a chemical agent such as an alkaline solution of sodium metasilicate, the oil may be selectively separated from its contaminants allowing its further use. -i-
