NONHYDROCARBON GAS SEPARATION DEVICE AND NONHYDROCARBON GAS SEPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/056135
Kind Code:
A1
Abstract:
[Problem] To provide a nonhydrocarbon gas separation device which, while avoiding upsizing, can raise the discharge pressure of a nonhydrocarbon gas towards the outflow side. [Solution] In this nonhydrocarbon gas separation device, a first and second separation module 2a, 2b connected in series separate a nonhydrocarbon gas from natural gas by means of a separation membrane 20. The nonhydrocarbon gas separated from the natural gas is discharged to each of discharge lines 202, 204. At that time, the pressure in the first separation module 2a on the side of the discharge line 202 is higher than the pressure in the second separation module 2b on the side of the discharge lines 204, 202.
