description: The theme of the final qualification work: "Designing a piston compressor for a natural gas liquefaction unit for a small CNG filling station". This work is devoted to CNG stations, small plants for the production of liquefied gas. As part of the work, the relevance of using gas motor fuel, its varieties, the advantages and disadvantages of each type of fuel, in particular, the advantages of using liquefied natural gas compared to compressed natural gas, were studied. The analysis of CNG filling stations existing on the territory of the Russian Federation and projects submitted for implementation in the next ten years was carried out. A study of natural gas liquefaction technologies was carried out, their comparative analysis and identification of the most economically and technically profitable solution for the given parameters of CNG filling stations. A schematic diagram of a natural gas liquefaction plant for CNG filling stations was designed, for which a thermal calculation of a natural gas liquefaction plant was carried out, the plant operation cycles were built, a compressor for the nitrogen cooling circuit was selected, a thermodynamic calculation of the compressor for the carbon dioxide circuit was carried out, the geometric dimensions of the unit were obtained with its subsequent design in CAD program.
