  • Publication number: 20180171831
    Abstract: Systems and methods are provided for the recovery mechanical power from heat energy sources using a common working fluid comprising, in some embodiments, an organic refrigerant flowing through multiple heat exchangers and expanders. The distribution of heat energy from the source may be portioned, distributed, and communicated to each of the heat exchangers so as to permit utilization of up to all available heat energy. In some embodiments, the system utilizes up to and including all of the available heat energy from the source. The expanders may be operatively coupled to one or more generators that convert the mechanical energy of the expansion process into electrical energy, or the mechanical energy may be communicated to other devices to perform work.

  • Patent number: 9127571
    Abstract: Systems and methods are provided for the use of systems that recover mechanical power from waste heat energy using multiple working expanders with a common working fluid. The system accepts waste heat energy at different temperatures and utilizes a single closed-loop circuit of organic refrigerant flowing through all expanders in the system where the distribution of heat energy to each of the expanders allocated to permit utilization of up to all available heat energy. In some embodiments, the system maximizes the output of the waste heat energy recovery process. The expanders can be operatively coupled to one or more generators that convert the mechanical energy of the expansion process into electrical energy.

  • Patent number: 9115603
    Abstract: Apparatus, systems and methods are provided for the use of multiple organic Rankine cycle (ORC) systems that generate mechanical and/or electric power from multiple co-located waste heat flows using a specially configured system of multiple expanders operating at multiple temperatures and/or multiple pressures (“MP”) utilizing a common working fluid. The multiple ORC cycle system accepts waste heat energy at different temperatures and utilizes a single closed-loop cycle of organic refrigerant flowing through all expanders in the system, where the distribution of heat energy to each of the expanders allocated to permit utilization of up to all available heat energy, In some embodiments, the multiple ORC system maximizes the output of the waste energy recovery process. The expanders can be operatively coupled to one or more generators that convert the mechanical energy of the expansion process into electrical energy.
