Application of Wobo’s CO2 Separation Membranes in Oilfield Associated Gas Decarbonization

‌Oilfield associated gas is a valuable natural resource produced alongside oil. However, it often contains a significant amount of carbon dioxide (CO2), making it unsuitable for direct entry into natural gas pipelines. Many small oil extraction plants burn this CO2-rich gas on-site, wasting natural gas and releasing CO2 into the atmosphere, causing pollution. Compared to other CO2 treatment methods for associated gas, membrane separation is considered the most ideal due to its low energy consumption, small investment, and compact footprint.

Wobo has developed S-series, E-series, and H-series CO2 separation membranes to meet various CO2 separation needs in natural gas, biogas, oilfield associated gas, and flue gas. These membranes are widely used for decarbonizing and reusing oilfield associated gas, biogas separation, natural gas purification, and flue gas capture. The E-series membranes can be used for natural gas decarbonization, desulfurization, and helium extraction. The H-series membranes are specially designed to handle the light oil content in oilfield associated gas, offering excellent oil and gas resistance, making them suitable for decarbonizing and reusing associated gas and tertiary oil recovery tail gas.

Wobo’s CO2 separation membranes are primarily designed to preferentially allow acidic gases to pass through, making them also suitable for separating and concentrating hydrogen sulfide (H2S) and sulfur dioxide (SO2).
