Natural Gas Sweetening - CO2 Enhanced Oil Recovery [ Return towards Natural Gas Sweetening ]

• Enhanced Oil Recovery with CO2

Recover CO2 for reservoir re-injection to improve oil production
EOR gas typically contains high levels of CO2 (>50%), the CO2 content usually increasing significantly overtime. MEDAL membranes separate the EOR gas into a CO2 enriched stream and natural gas.CO2 enriched gas is recompressed and injected in the wells.
Benefits are extension of oil reservoir production life, environmentally friendly technology (CO, sequestration).
