Pipeline-quality natural gas after molecular-gate CO2 removal

The feed source of a proprietary molecular-gate CO 2 -removal system is a hydrocarbon-rich, water-saturated associated gas from waterflood operations. The feed CO 2 concentration varies and is typically more than 30%. The unit reduces the CO 2 level to less than 2%. The unit can remove the CO 2 , heavy hydrocarbons, and water, yielding pipeline-specification gas for sale to the local natural-gas utility company.
