ABSTRACT:
A Cascading Closed Loop Cycle (CCLC) system is described for recovering power in the form of mechanical or electrical energy from any thermal energy source whose temperature is sufficiently high to vaporize a pressurized light hydrocarbon medium such as propane or propylene. A light hydrocarbon medium is vaporized in multiple indirect heat exchangers; expanded in multiple cascading expansion turbines to generate useful power; and condensed to a liquid using a cooling system. The light hydrocarbon liquid medium is then pressurized with a pump and returned to the indirect heat exchangers to repeat the vaporization, expansion, liquefaction and pressurization cycle in a closed, hermetic process.
