Abstract
A gas storage apparatus comprises a pressure vessel in the form of a cylinder, closed by a valve, containing a non-permanent gas having under its storage conditions a gas phase and a liquid phase. A jacket formed of plastics sachets surrounds and is in heat transfer relationship with the outer surface of the cylinder. The sachets define closed compartments containing a heat release substance which is liquid at 20° C. On opening the valve, the non-permanent gas is delivered from the cylinder. The liquid phase of the non-permanent gas absorbs heat from the heat release substance which undergoes fusion. The heat release substance may be water.
Claims18
A gas storage apparatus comprising:
- a pressure vessel containing a non-permanent gas, stored under conditions wherein both a gas phase and a liquid phase are present;
- a valve closing the pressure vessel;
- a jacket surrounding and in heat transfer relationship with the outer surface of the pressure vessel;
- the jacket comprising a plurality of closed compartments each containing a heat release substance that releases heat to the liquid phase of the non-permanent gas by undergoing a change of state from liquid to solid.
A gas storage apparatus comprising;
- a pressure vessel containing a non-permanent gas, stored under conditions wherein both a gas phase and a liquid phase are present;
- a valve closing the pressure vessel;
- a jacket surrounding and in heat transfer relationship with the outer surface of the pressure vessel;
- the jacket comprising a plurality of closed compartments each containing a heat release substance that releases heat to the liquid phase of the non-permanent gas by undergoing a change of a state from liquid to solid;
- further comprising a cylindrical guard sleeve surrounding and spaced from the jacket wherein the guard sleeve comprises a pair of engaging semi-cylindrical members.
A gas storage apparatus comprising:
- a pressure vessel containing a non-permanent gas, stored under conditions wherein both a gas phase and a liquid phase are present;
- a valve closing the pressure vessel;
- a jacket surrounding and in heat transfer relationship with the outer surface of the pressure vessel;
- the jacket comprising a plurality of closed compartments each containing a heat release substance that releases heat to the liquid phase of the non-permanent gas by undergoing a change of state from liquid to solid;
- further comprising a cylindrical guard sleeve surrounding and spaced from the jacket wherein the guard sleeve is made of a transparent plastic material.
A gas storage apparatus comprising:
