ABSTRACT:
A process, apparatus and control methodology for transferring loads between drivers in adjacent refrigeration cycles in a cascaded refrigeration process has been developed thereby enabling more efficient driver operation. Load transfer is effected by cooling the higher boiling point refrigerant liquid prior to flashing via an indirect heat transfer with the lower boiling point refrigerant vapor in a adjacent cycle prior to compression of said stream.
