Abstract:
A production method for natural gas according to the invention includes a step of adiabatically compressing a raw natural gas containing helium gas, a step of separating the helium gas from the raw natural gas by passing the adiabatically-compressed raw natural gas through a separation membrane unit, a step of conveying the raw natural gas from which the helium gas has been separated to a terminal through a pipe line, and a step of pressing the helium gas separated from the raw natural gas into an underground storage formation.
