Title: Power recovery and feedback system

Patent ·
OSTI ID:5693540

A system for recovering otherwise lost power from a compressor and prime mover utilizing a Rankine cycle is disclosed. While heat recovery from prime movers has been done, much energy is wasted by compressors which convert all the driving power to heat which has not been recovered. Thus, this invention provides for power recovery from both the prime mover and the compressor. A working fluid is pre-heated utilizing waste heat from the prime mover and compressor, such as that in the cooling medium, oil cooler, and the like. The pre-heated working fluid is passed to a boiler where it is vaporized and super heated and then is passed to a turbine or other type of expander. From the turbine, the working fluid goes to a condenser and is then pumped to the heat exchanger, or heat exchangers, to begin another cycle. The turbine or other type of expander is used to supplement the prime mover in driving the compressor or for any other suitable application of power.
