Success Stories Built on Existing Membrane Materials and Formation Technology

Success Stories Built on Existing Membrane Materials and Formation Technology 

Valuable savings are possible even using available gas and vapor-separation membrane units, while aggressively pursuing development of nonaqueous RO and its larger energy payoffs over the next decade. Vapor-separation processes are operationally similar to gas-separation units but often use a moderate vacuum downstream, depending upon the vapor pressure of the components at the feed temperature. 

Membrane technology for natural-gas separations is gaining broad acceptance and a number of major membrane-separation plants have come into operation in recent years. These include the Cakerawala production platform (CKP) that processes 700 MMScfd with a 37% C02 feed and a plant in Qadirpur, Pakistan that processes 500 MMscfd of 6.5 mole% C02 feed to 2% C02 pipeline specification [26]. Current plans are being made to double production at the CKP facility [27].
