ABSTRACT:
Disclosed is a process for treating oily wastes, which have a predominantly liquid phase, by mixing the oily waste with a granulating medium under turbulent flow conditions. The process comprises mixing the oily waste with a granulating medium under such conditions, wherein granules are formed having an attrition index of less than about 10 percent and a filtration index of greater than 0.20 gallons per minute per square foot. The contaminating hydrocarbons may then be removed by contacting the granules with a solvent capable of removing at least a portion of the contaminating hydrocarbons. The granules are then recovered by means known in the art.
