摘要： A method for withdrawing from a vessel pressurized cryogenic helium fluid with an objectionable impurity concentration of less than 5 ppmv. The method comprises pressurizing at or near the top of the vessel with helium fluid from an external source having a concentration of up to 1000 ppmv of the objectionable impurity, and withdrawing from a port near the bottom of a vessel helium fluid at a cryogenic temperature below the temperature at which the withdrawn fluid has an objectionable impurity of 5 ppmv.

摘要： A system and process for recovering high purity coolant gas from at least one fiber optic heat exchanger, characterized by controlling a flow of coolant gas into and out of the heat exchanger using a pressure, impurity and/or flow rate monitoring or transmitting means in conjunction with a flow adjusting or controlling device to limit air or other gas infiltration into at least one fiber optic passageway of the heat exchanger. A sealing means may also be used at at least one end of the fiber optic passageway to further reduce air or other gas infiltration into the passageway. The resulting high purity coolant gas from the outlet of the heat exchanger is delivered to the inlet of the heat exchanger. Optionally, the resulting coolant gas from the outlet of the heat exchanger may be cooled, filtered and/or purified before being delivered to the inlet of heat exchanger.

摘要： A process and system for pressurizing a vessel for integrity testing with gas comprising helium, recovering the gas comprising helium, and purifying the gas comprising helium for reuse. The process for purifying the gas stream comprising helium comprises drying the gas stream; separating the dried gas stream in a membrane separator stage into a helium-enriched permeate product stream and a helium-depleted raffinate stream; recovering helium in the raffinate stream in a membrane stripper stage thereby producing a purge stream; and purging water from the dryer with the purge stream.
