ABSTRACT:
Inert gas blanket protects oxidatively labile substance from oxidation. For example, fuels and lubricants such as present in fuel tanks, bearings, crankcases, gear boxes, transmissions, and so forth, employed in or in conjunction with internal combustion, jet and turbine engines, or a combustible substance such as flour dust in a grain silo, can be protected with a nitrogen blanket provided from the separation of air with a membrane containing device. Useful life of oleaginous liquids and hydrocarbon-based lubricants can be extended. For example, with the practice of the present invention, it may be necessary to change automobile engine oil only after twenty to fifty thousand miles of use.
