Abstract
A system delivers cryogenic gas at a high pressure from a supply of cryogenic liquid maintained at a low pressure in a bulk tank. The bulk tank supplies liquid to at least one transfer tank. The transfer tank is pressurized by connecting it to a pressure building tank contaning gas at a high pressure. A heat exchanger is connected in circuit between the transfer tank and the pressure building tank. The transfer tank provides liquid at a high pressure to the heat exchanger so that a vapor is produced. This vapor is fed to the pressure building tank so that the high pressure therein is maintained. The transfer tank provides a high pressure flow of liquid to a vaporizer and a high pressure gas storage tank so that high pressure cryogenic gas may be produced and stored.
