INTEGRATED ORC PROCESS ON COMPRESSORS HAVING INTERSTAGE COOLING FOR INCREASING THE EFFICIENCY AND DECREASING THE REQUIRED DRIVE POWER BY USING THE THERMAL DISCHARGE

摘要

The invention relates to an energy conversion arrangement (100) for converting thermal energy into mechanical work. A working medium in the vaporous state can be supplied to a capacitor (110), wherein the capacitor (110) is configured to transfer the working medium from the vaporous state into a liquid state by means of cooling down said working medium. An evaporator (120) is coupled to the capacitor (110) such that the working medium in the liquid state can be supplied from the capacitor (110) to the evaporator (120). The evaporator (120) can be coupled to a compressor arrangement (160) in such a way that thermal energy can be discharged from a process fluid to be compressed of the compressor arrangement to the working medium in the evaporator (120), wherein the evaporator (120) is configured to transfer the working medium from the liquid state into the vaporous state by means of the thermal energy of the process fluid. A turbine (130) for converting thermal energy into mechanical work is coupled to the evaporator (120) in such a way that the working medium can be supplied from the evaporator (120) to the turbine (130). Furthermore, the turbine (130) is coupled to the capacitor (110), and so the working working medium can be supplied from the turbine (130) to the capacitor (110).
