Abstract

This invention provides means for producing power by using isothermal compressors and isothermal expanders. One embodiment has an isothermal compressor that compresses air (or other gas), passes the air through a counter- flow heat exchanger, which heats the air, uses the heated air to drive an isothermal expander for power generation, and transfers the expander exhaust back through the counter-flow heat exchanger to heat the input air to the expander. Another embodiment has a boiler that produces vapor that flows through a counter-flow heat exchanger to superheat the vapor. The vapor then flows through an isothermal expander for power generation. The exhaust from the isothermal expander flows back through the counter-flow heat exchanger to supply heat to the vapor coming from the boiler and then flows through another heat exchanger that preheats the feed liquid flowing to the boiler.
