Abstract:
1. A system for simultaneously converting a portion of heat from at least two heat source streams to a usable form of energy comprising: an energy conversion subsystem, where a portion of heat or thermal energy associated with a superheated working solution stream is converted to a usable form of energy forming a spent working solution stream; a vaporization and superheating subsystem including: a heat exchange, separation and condensation subsystem including at least three heat exchange units, a gravity separator and three pumps, where the heat exchange, separation and condensation subsystem forms a condensing solution stream, a rich vapor stream, a liquid lean solution stream and a lower pressure rich basic solution stream from a spent working solution stream, heats and cools different streams, separates the condensing solution stream into the rich vapor stream and the liquid lean solution stream, fully condenses the lower pressure rich basic solution stream using an external coolant stream, divides the lean solution stream into three substreams, pressurizes the fully condensed lower pressure rich basic solution stream and dividing the higher pressure rich basic solution stream into two substreams after heating to partially vaporize the streams in the at least two of the heat exchangers.
