Abstract
Contaminating water and/or fuel material may be removed from a stream of internal combustion engine lubricating oil being circulated over parts of an operating engine. A suitable membrane material is supported in a suitable housing. At least a portion of the oil stream is flowed over one side of the membrane and water and/or fuel material diffuses through the membrane to its other side where they are gathered and removed from the housing. The water and fuel material may be recovered separately using different membranes or different regions of a membrane. They may be swept from the membranes and housings using streams of flowing air heated to a pre-selected temperatures using waste engine heat for disposition outside the housing. Application of this practice to other membrane-separable mixtures is described.
