Abstract: Heat recovery systems and methods for producing electrical and/or mechanical power from a process heat by-product are provided. Sources of process heat by-product include hot flue gas streams, high temperature reactors, steam generators, gas turbines, diesel generators, and process columns. Heat recovery systems and methods include a process heat by-product stream for indirectly heating a working fluid of an organic Rankine cycle. The organic Rankine cycle includes a heat exchanger, a turbine-generator system for producing power, a condenser heat exchanger, and a pump for recirculating the working fluid to the heat exchanger.

Abstract: Heat recovery systems and methods for producing electrical and/or mechanical power from heat by-product of an overhead stream from a process column are provided. Heat recovery systems and methods include a process heat by-product stream for directly or indirectly heating a working fluid of an organic Rankine cycle. The organic Rankine cycle includes a heat exchanger, a turbine-generator system for producing electrical or mechanical power, a condenser heat exchanger, and a pump for recirculating the working fluid to the heat exchanger.
