Biogas Treatment

During anaerobic digestion or degradation in the absence of oxygen, organic material is decomposed by bacteria forming biogas, a mixture of CO2 and CH4 with trace amounts of H2S and H2O. The biogas can be used as vehicle fuel, in industrial processes or injected into the gas distribution grid, but first needs to be treated.

GENERON® membrane systems are used to reduce the CO2 and improve the heating value of the gas. The systems also reduce or remove the H2S, Siloxane and H2O content. The customized biogas membrane systems (which can also include the feed compressor) are manufactured in our ISO 9000 Certified facilities in Houston, TX while the membrane is manufactured in our Pittsburg, CA facility.

In a typical GENERON® biogas membrane system the feed gas is filtered to remove any entrained aerosols and liquids. The gas then enters the GENERON® membrane filters. The CO2 as well as any H2S and H2O permeate through the membrane. The non-permeated gas, mainly CH4, remains at pressure and is the product gas.
