A method for the cryogenic separation of air having defined temperatures for condensed feed air passed into a double column system relative to liquid oxygen and preferably to shelf vapor, and wherein kettle liquid is not subcooled from the higher pressure column to the lower pressure column.

Cryogenic air separation method with temperature controlled condensed feed air

A cryogenic rectification system employing a phase separator, which may include one or more trays, in conjunction with a double column air separation plant, wherein some shelf liquid is subcooled and phase separated to produce crude neon vapor, and the remaining liquid is used to reflux the lower pressure column of the double column plant.

Cryogenic rectification system for neon production

A cryogenic air separation system having enhanced liquid production capacity wherein a feed air stream bypasses the primary heat exchanger and is processed through cooling and warming passes of a feed air liquefier to produce liquid feed air for introduction into the cryogenic air separation plant.

Cryogenic air separation system with enhanced liquid capacity

A method for generating refrigeration, especially over a wide temperature range including cryogenic temperatures, wherein a non-toxic, non-flammable and low or non-ozone-depleting mixture is formed from defined components and maintained in variable load form through compression, cooling, expansion and warming steps in a refrigeration cycle.

Variable load refrigeration system particularly for cryogenic temperatures

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.

Cryogenic rectification system with pulse tube refrigeration

A cryogenic air separation process for producing liquid oxygen and other liquid products wherein refrigeration generation for the process is decoupled from the flow of process streams and is produced at least in part by at least on multicomponent refrigerant fluid refrigeration circuit.

Cryogenic air separation process for producing liquid oxygen

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.

Cryogenic air separation process for producing elevated pressure gaseous oxygen

A cryogenic air separation process having improved flexibility and operating efficiency wherein refrigeration generation for the process is decoupled from the flow of process streams and is produced by one or more closed loop circuits.

Cryogenic air separation process for producing gaseous nitrogen and gaseous oxygen

A cryogenic rectification method wherein both nitrogen gas and liquid are efficiently produced from air employing one or two columns wherein refrigeration to drive the cryogenic separation is provided by a, preferably closed loop, multicomponent refrigerant fluid refrigeration circuit.

Cryogenic rectification method for producing nitrogen gas and liquid

A system for generating refrigeration and providing the refrigeration into a cryogenic rectification plant wherein, in addition to refrigeration generated by turboexpansion, further refrigeration for the plant is generated by a recirculating multicomponent refrigerant in a refrigeration circuit.

Cryogenic rectification system and hybrid refrigeration generation

A method for more efficiently cooling and liquefying industrial gas wherein refrigeration for the cooling and liquefaction is generated using first and second defined multicomponent refrigerant fluids in separate refrigeration circuits to cover a wide temperature range from ambient to cryogenic temperature.

Multiple circuit cryogenic liquefaction of industrial gas

Variable load refrigeration system particularly for cryogenic

A system for cooling a fluid particularly to a cryogenic temperature wherein a multicomponent refrigerant fluid is partially condensed, the liquid used to generate refrigeration to cool the product by recycle into an upstream portion of the warming leg of the refrigeration circuit, and the vapor, having a different composition than the liquid, is used to generate refrigeration at a colder temperature for further cooling of the product.

Multicomponent refrigerant cooling with internal recycle

A method for low temperature separation of fluids wherein the separation process is sustained by refrigeration generated by a recirculating multicomponent refrigerant fluid.

Method for carrying out subambient temperature, especially cryogenic,

A method for liquefying an industrial gas wherein a portion of the requisite refrigeration is generated by a multicomponent refrigerant circuit and a portion is generated by turboexpansion of either a portion of the industrial gas or a portion of the multicomponent refrigerant.
