Structure and Parameters Optimization of Organic Rankine Cycle System for Natural Gas Compressor Exhaust Gas Energy Recovery

In the paper, the structure and working principle of free piston based organic rankine cycle (ORC) exhaust gas energy recovery system have been presented in detail. A GT-Power software based prototype model has been established in order to find out the effects of different parameters. Comparisons under different thermo parameters of heated and cold work material have been analyzed thoroughly. Simulation results show that the thermo parameters of heated work material are very sensitive to net heat efficiency.
