1. A heat engine system, comprising:

  • a working fluid circuit having a high pressure side and a low pressure side and being configured to flow a working fluid therethrough;

    a plurality of waste heat exchangers, wherein each of the waste heat exchangers is configured to be fluidly coupled to and in thermal communication with the high pressure side of the working fluid circuit, to be fluidly coupled to and in thermal communication with a heat source stream, and to transfer thermal energy from the heat source stream to the working fluid within the high pressure side;

    a plurality of recuperators, wherein each of the recuperators is fluidly coupled to the working fluid circuit and configured to transfer thermal energy between the high pressure side and the low pressure side of the working fluid circuit;

    a first expander fluidly coupled to the working fluid circuit, disposed between the high pressure side and the low pressure side, and configured to convert a pressure drop in the working fluid to mechanical energy;

    a second expander fluidly coupled to the working fluid circuit, disposed between the high pressure side and the low pressure side, and configured to convert the pressure drop in the working fluid to mechanical energy;

    a first pump fluidly coupled to the working fluid circuit between the low pressure side and the high pressure side of the working fluid circuit and configured to circulate or pressurize the working fluid within the working fluid circuit; and

    a first condenser configured to be in thermal communication with the working fluid on the low pressure side of the working fluid circuit and configured to remove thermal energy from the working fluid on the low pressure side of the working fluid circuit.
