  • Patent number: 7617848
    Abstract: A method and device for filling a container with liquid gas from a storage tank includes removing the liquefied gas from the storage tank and feeding it to a container via a liquid feed line through use of a delivery system. The gas is compressed in the container and is removed from the container in its gaseous state and is at least partially liquefied by cooling in a heat exchanger. The at least partially liquefied gas is fed into the liquid feed line at the suction end of the delivery device.
    Type: Grant
    Filed: July 19, 2005
    Date of Patent: November 17, 2009
    Assignee: Messer France S..A.S.

  • Patent number: 6948323
    Abstract: Supply of liquefied gases. The plant is characterized in that: *the withdrawal outlet is provided with a transfer pump (16) and with an ejector (17) which are located upstream of the fitting (11); *the ullage space of the container is equipped with a gas phase recycling line (5) equipped with a fitting (15); and * heat exchange means (19) are interposed in order to:—condense all or a portion of the recycled gas phase from the container and reinject it in liquid form into the ejector where any further condensation is completed,—vaporize a portion of the liquid phase from the tank in order to maintain the gas phase occupying the ullage space of the latter. Application to the filling of several containers by a mobile tank.
