ABSTRACT:
A method and apparatus for implementing a thermodynamic cycle with preheating, involves expanding a gaseous working fluid to a medium pressure to transform its energy into usable form. The expanded gaseous working fluid is split into two different streams. One stream is further expanded to a spent low pressure level to produce further usable energy. This stream is then condensed. The other of the two streams is used to preheat the condensed stream and is mixed with the condensed stream at a point upstream of the point of preheating. This decreases the irreversibilities in the preheating process and enables greater efficiencies to be achieved.
