Pressure control of cryogenic liquids |
摘要 |
A pressure control system comprises separate conduits for supplying liquefied gas and vapor from a cryogen space defined by a cryogenic storage tank. A first conduit can deliver liquefied gas to a use device through a heater and then a first flow controller. A second conduit can deliver vapor to the use device with flow therethrough controlled by a second flow controller. The first flow controller is not exposed to liquefied gas at cryogenic temperatures because it is located downstream from the heater. For automatic operation a pressure sensor measures pressure inside the cryogen space and the first and second flow controllers are independently operable to maintain the pressure inside the cryogen space within a predetermined range. In a preferred embodiment the liquefied gas is a combustible fuel that is consumed by an internal combustion engine, which is the use device. |
