826,135. Storing gases under pressure. MUCK, O. H. Jan. 19, 1956 [Jan. 19, 1955; May 18, 1955; Aug. 8, 1955; Oct. 31, 1955], No. 1854/56. Class 8(2). [Also in Group XXXIII] Natural gas mostly methane is liquefied at source by countercurrent heat exchange with liquid nitrogen having been transported in a container from a distant low temperature air separation plant, the so liquefied natural gas is then passed at substantially atmospheric pressure into the container previously occupied by the liquid nitrogen and is transported to said distant place where is it revapourized in heat-exchange with compressed nitrogen gas issuing from the air separation plant which nitrogen is thereby liquefied and is fed to the tank space vacated by the methane. The container which may be carried by a road vehicle or in a ship's hold (see Group XXXIII) may be of steel lined with concrete or of aluminium sheathed by concrete or metallised plastic. Specification 766,128 is referred to. |
