1. A process for recovering electrical power from a steam reboiler system, the process comprising:

  • converting an inlet liquid process stream from a processing unit into a vapor phase and a liquid phase in a reboiler;

    heating the inlet liquid process stream within the reboiler with a stream of steam using a heat exchanger having an inlet and an outlet;

    reducing a pressure of the stream of steam with a turbine prior to heating the inlet liquid process stream, wherein the steam after the pressure reduction comprises a superheat steam, and the degrees of superheat in the steam after passing through the turbine is less than 20 degrees C.;

    recovering condensate from the outlet after heating the inlet liquid process stream;

    rotating a turbine wheel within the turbine, the turbine wheel configured to transmit rotational movement to an electrical generator;

    generating electricity with the turbine;

    receiving information from the turbine relative to an amount of electricity generated by the turbine;

    receiving information associated with a throughput of the processing unit; and

    ,determining an electrical power generated target based in part upon the information associated with the throughput of the processing unit,wherein the amount of electricity generated by the turbine meets or exceeds the electrical power generated target, and wherein the process further comprisesmaintaining the throughput of the processing unit while reducing a flow of fuel to a heater producing the stream of steam.
