ABSTRACT:
In combination, pressurized fluid contained in a storage vessel, in both liquid and vapor regions, a heat exchanger in the vapor region of the vessel, and a first pressure regulator having an inlet side in communication with liquid in the vessel, and having an outlet side in communication with the heat exchanger, whereby if pressure in the vessel rises to the setting of the regulator, it opens and admits liquid from the vessel to the heat exchanger, to vaporize in that exchanger causing vapor in the vessel to condense, and reducing pressure in the vessel.
