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 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 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 serial column system for producing relatively large quantities of both high purity nitrogen gas and high purity nitrogen liquid using a first column producing the high purity gas and a second column producing the high purity liquid, with second column top fluid refluxing the first column.
