    Abstract: A movable pressure vessel has an insulated wall portion for limiting the temperature rise of liquefied gas therewithin. A relief valve is provided for limiting the pressure within the vessel to establish a working pressure. The filling means of the vessel includes a relief valve for limiting the maximum pressure of the gas entering the vessel to a pressure of approximately 15 p.s.i.g. less than the working pressure of the vessel. Liquefied gas is loaded into the vessel at a maximum temperature and pressure as determined by the relief valve in the filling means, and temperature rise of the liquefied gas during transport is limited so that the pressure produced by the gas does not exceed the working pressure of the vessel. A vapor return means extends along the bottom of the vessel and opens therewithin at a point remote from the outlet means of the vessel and adjacent the front end of the vessel.
