Abstract

An apparatus for storing liquefied gas having a boiling point below 233º k at atmospheric pressure and supplying gas material therefrom, including the combination of a pressure vessel for containing a supply of liquefied gas, and having normal liquid spaces and gas; heat insulation surrounding said container, of a thickness and type such that the heat input through the insulation to said container is restricted to no more than 0.420 kilocalories, per hour, per square cm dcm of the container surface under a differential temperature of 200º c; a service connection for consumer apparatus that requires gas material at a desired service pressure; automatic pressure devices comprising an external vaporizer having a connection to the liquid and gas spaces of said container and an automatic fluid control device interposed and having an operating element to respond to the pressure changes endin container for controlling the vaporization of liquefied gas parts in response to the pressure of said vessel to maintain the pressure therein at a predetermined substantially constant operating value within the chosen limits; and extraction step devices connected between said container and said service connection for supplying gas material at a substantially constant operating pressure and including connected devices to respond to the demand to stop such supply of gas material when the gas demand for the consumer apparatus ceases; the passage of heat to said container then being absorbed, mainly, as sensible heat in the liquid and container for an abnormally long period of no demand before the pressure in the container reaches a predetermined value over said operating pressure.
