The study considers the possibility of using the Ranque-Hilsch vortex tube in the construction of a heat exchanger for heating fuel gas to ensure normal operation of the gas-pumping units used to pump gas into the underground gas storages. According to the results of the gas-hydrodynamic and thermal methods for calculating structural elements, a final equation was obtained describing combined operation of the vortex tube and heat exchanger. The calculation method allows taking into account the impact of the main temperature and design parameters. The results of technical and economic calculations and thermal modeling based on the SOLIDWORKS program make it possible to judge the effectiveness of the proposed design.
