  • Helium gas separator material and method for producing the same
    Patent number: 9486734
    Abstract: The helium gas separator material includes a base portion and a gas separation portion joined to the base portion. The base portion is composed of a porous ?-alumina material which has communication holes with an average diameter of 50 nm to 1,000 nm; the gas separation portion has a porous ?-alumina portion containing a Ni element and a silica membrane portion which is disposed on the inner wall of the communication holes in the porous portion; and the average diameter of pores surrounded and formed by the silica membrane portion is 0.27 nm to 0.60 nm.
    Type: Grant

  • Production method and production system for natural gas
    Patent number: 9417008
    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.
