Patent ID: 7458217

Claim:
A system comprising: an internal combustion engine including a cooling system, a heat recovery vapor generator (HRVG) connected to an exhaust of the engine and adapted to utilize heat in exhaust gases produced by the internal combustion engine to fully vaporize a fully condensed multi-component working fluid stream, a turbine connected to the HRVG for converting a portion of thermal energy in the fully vaporized multi-component working fluid stream to a usable form of energy to form a spent multi-component working fluid stream, and a condensation thermal compression subsystem (CTCSS) connected to the turbine and to the cooling system, where the CTCSS comprises a plurality of heat exchangers, at least two pumps, a separator, at least one throttle valve, and a plurality of mixing and combining valves, where the CTCSS is adapted to fully condense the spent multi-component working fluid stream to form the fully condensed working fluid stream utilizing heat from a cooling system stream, transferring heat between a plurality of stream comprising three different compositions of the multi-component working fluid and transferring heat to external coolant streams to form fully condensed streams including the fully condensed multi-component working fluid stream.
