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.
[ We claim:] [1.] A method for providing refrigeration for a cryogenic rectification plant comprising:(A) compressing a multicomponent refrigerant fluid, expanding the compressed multicomponent refrigerant fluid to produce refrigeration and warming the expanded multicomponent refrigerant fluid by indirect heat exchange with a process fluid thereby passing refrigeration from the refrigerant fluid into the process fluid;(B) passing refrigeration from the process fluid into the cryogenic rectification plant;(C) turboexpanding a fluid stream to generate refr...
