Abstract: 1,066,719. Liquefied gas storage containers. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Jan. 12, 1966, No. 1538/66. Heading F4P. A heat insulated liquid methane storage reservoir of vertical cylindrical form is divided by a horizontal vertically movable wall (8), Fig. 1 (not shown) into a lower space (9) to which iso-pentane is admitted and withdrawn through a duct (7) and on which the wall (8) floats and into an upper space (11) to which liquid methane is admitted and withdrawn through ducts (17 to 24) extending through the reservoir side walls (3, 4) and the dividing wall (8). The latter comprises a metal box charged with compressed nitrogen and having sealing rings (15) engaging the inner wall (3). In operation and assuming the wall (8) being adjacent the reservoir top (2) liquid methane is pumped from a tanker into space (11) and the isopentane forced from space (9) into the tanker space vacated by the liquid isothane and the cold content thereof is used to liquefy gaseous methane prior to shipment. Similarly liquid methane removed from space (11) is used to liquefy gaseous isopentane prior to it being supplied to space (9). The reservoir may be mounted on a concrete foundation (6) or it may be set in a ground excavation.
