Annotation:
The article presents the results of modeling vortex ejector systems and devices, the principle of operation of which is to use the Rank – Hilsch effect arising in vortex tubes. The conducted theoretical and experimental studies have shown the possibility and feasibility of their use at compressor stations for pumping process gas from closed volumes of process pipelines in order to reduce technological losses and increase the energy efficiency of gas transmission systems. The calculation based on the created digital model of a vortex ejector compressor allows finding its operational characteristics, pumping time and gas residual pressure from a closed volume, according to the specified design and operating parameters. The conducted research made it possible to create a prototype of a jet two-stage ejector for pumping natural gas from the communications of the centrifugal supercharger of the gas pumping unit.
