The EPS Gas Membrane System includes a vapor recovery system comprising a gas blower or compressor, pressure vessels, colvent resistant membrane which is constructed from special selective gas permeable membranes. This product gas can then be reclaimed with the use of a vacuum pump and condensation. These elements can be operated in series to maximize the recovery of gases and make the most efficient use of input energy. The resultant purified air can be exhausted or recycled back for reuse in case there is an energy or BTU value, ie. industrial buildings. The EPA Gas Membrane System offers unique advantages over other gas seperation routes.
