In this paper, the application of various non-ozone-depleting low-boiling working fluids for the Rankine cycle is analyzed based on exergy efficiency. The Rankine cycle is used for high-efficiency waste heat recovery from flue gases generated in gas transport systems at natural gas compressor stations. The system was modelled based on calculations using the CHEMCAD software in conjunction with the “Energy unit” module compatible with the main program interface, which was used for assessing system energy efficiency. It was concluded that the neopentane Rankine cycle with a regenerator is more efficient. Preliminary economic analysis has shown that the proposed system has an acceptable payback period (up to 6 years).
