摘要:
A cryogenic nitrogen production plant wherein all the heat transfer steps, and preferably all the heat transfer and separation steps, are carried out in a brazement which receives feed air and from which is recovered product nitrogen.
摘要:
A cryogenic air separation comprising an integrated core and typically including a double column wherein incoming feed air is cooled in the core which also processes a stream from the double column. A separating section of the core processes a stream from the double column to product.

摘要:
A cryogenic air separation system wherein an integrated core receives and cools an incoming feed air stream, a rectification section facilitates mass transfer of the feed air stream, a separation section in a heat exchange relationship with the rectification section processes fluid from the rectification section, and a section in a heat exchange relationship with an entrance passage discharges fluid from the integrated core.
摘要:
A pulse tube refrigeration system wherein the pulse tube working gas is cooled to a defined first stage temperature and is brought to a defined second stage temperature by operation of a regenerator and pulse tube, which are in flow communication through a cold heat exchanger, prior to providing refrigeration to a high temperature superconductor.
摘要:
A cryogenic rectification system wherein some or all of the refrigeration necessary to drive the rectification is generated by periodically magnetizing and demagnetizing a bed of magnetizable material, passing refrigerator gas through the bed to produce cold refrigerator gas, and passing refrigeration from the cold refrigerator gas into the rectification system.
摘要:
A cryogenic rectification system wherein some or all of the refrigeration necessary to drive the rectification is generated by providing a pulse to a gas and then passing the compressed gas to a pulse tube wherein the gas expands in a wave generating refrigeration at one end of the pulse tube for transfer into the rectification system.
摘要:
A cryogenic air separation process having improved flexibility and operating efficiency for producing elevated pressure gaseous oxygen by vaporizing pressurized liquid oxygen wherein refrigeration generation for the process is decoupled from the flow of process streams and is produced by one or more multicomponent refrigerant fluid circuits.
摘要:
A food freezing system wherein refrigeration is generated by compressing, cooling and then expanding a defined multicomponent refrigerant mixture, which, after providing refrigeration to the food, is warmed against itself to effect the cooling.
摘要:
A pulse tube system especially useful for producing and delivering refrigeration at very cold temperatures wherein a product fluid such as hydrogen is preferably precooled and then liquefied, subcooled and/or densified by heat exchange with ultra cold gas generated by a pulsing compression wave which rejects heat into a cryogen fluid heat sink.
