摘要:
A cryogenic refrigeration system wherein refrigeration is provided to a heat load by a warming multicomponent refrigerant fluid recirculating in a refrigeration circuit and by cryogenic liquid separately provided to the heat load in direct or indirect heat exchange with the heat load.
摘要:
A system for producing carbon dioxide wherein carbon dioxide feed fluid is first processed in a cooling section of an integrated heat exchanger before purification in a column, and wherein column bottom fluid operates within one of an evaporating section and desuperheating section of the heat exchanger and refrigerant fluid operates within the other of the evaporating section and desuperheating section of the heat exchanger.
摘要:
A method for generating refrigeration using a turboexpander or reverse Brayton cycle which can more efficiently generate refrigeration especially to cryogenic temperatures using a defined refrigerant mixture containing argon and/or nitrogen.
摘要:
A cryogenic air separation system employing a double column wherein lower pressure column bottom liquid is pressurized in a single cryogenic liquid pump to provide driving fluid for the main condenser and to provide product elevated pressure oxygen.
摘要:
A cryogenic rectification system wherein a product boiler is incorporated into the primary heat exchanger without encountering boiling to dryness problems wherein liquid from the cryogenic rectification plant is processed in a phase separator upstream of the product boiler, and fluid from the product boiler is passed into the phase separator prior to recovery.
摘要:
A refrigeration system wherein an ammonia refrigerant fluid in a cascade refrigeration circuit provides auxiliary refrigeration to a multicomponent refrigerant fluid which passes from an autorefrigerator to provide refrigeration to a heat load.
摘要:
A system wherein flashoff losses from cryogenic liquid tankage are reduced wherein fluid from the tankage is condensed and subcooled against refrigeration bearing refrigerant fluid generated by an exogenous refrigeration system.
