Membrane separation is a cost-effective way to remove CO2 from natural gas. The typical membrane treatment package usually consists of a relatively complex pre-treatment step followed by a simple membrane system. This paper will present another innovative All-Membrane Solution This All Membrane Solution consists of:
• a first stage of (polyether ether ketone) PEEK-SepTM membranes resistant to the main impurities in natural gas removing water heavy hydrocarbons and H2S simultaneously essentially replacing the pre-treatment for CO2 removal membrane,
• a second stage of polyimide membranes MEDAL PIX with extremely high CO2 / CH4 selectivity for CO2 removal
Key benefits are simplicity of operation and compactness of footprint.
