20090071171 | CRYOGENIC LIQUID STORAGE METHOD AND SYSTEM - A cryogenic liquid storage system and method in which cryogenic liquid is stored within an active cryogenic liquid storage tank and one or more passive cryogenic liquid storage tanks. Headspace regions of the passive cryogenic liquid storage tanks are connected to the active cryogenic liquid storage tank and the active cryogenic liquid storage tank is refrigerated to collapse the headspace vapor within the active cryogenic liquid storage tank causing the flow of headspace vapor from the headspace regions of the passive cryogenic liquid storage tanks to the active cryogenic liquid storage tank. The increased head of liquid produces a pressure differential that drives liquid from the active cryogenic liquid storage tank back to the passive cryogenic liquid storage tanks. In such manner, refrigeration applied to a single active cryogenic liquid storage tank can be used to refrigerate the passive cryogenic liquid storage tanks to prevent the venting of headspace vapor from all of the cryogenic liquid storage tanks. | 03-19-2009 |
