Document Type and Number:
WIPO Patent Application WO/2016/088538
Kind Code:
A1
Abstract:
Provided are a device and a system for refining natural gas, each of which are compact in the configurations thereof, are reduced in the amounts of energy consumption, and can refine natural gas with high quality. A natural gas refining device 1 according to the present invention incorporates a first separation membrane unit 11 which has a separation membrane therein and a second separation membrane unit 12 which is located downstream of the separation membrane unit 11 and has a separation membrane therein and through which an amine solution can pass, wherein unrefined natural gas that contains CO2 is allowed to pass through the first and second separation membrane units 11 and 12 to separate a CO2-rich gas through the separation membranes, and CO2 is absorbed by the amine solution that passes through the second separation membrane unit 12 to refine the unrefined natural gas.
