Most of the automobile gas-filling compressor stations (AGFCS) in Russia were built in the last quarter century. Now the equipment needs to be solid infrastructure modernization compressors installations. It is reported on the development of new efficient heat exchangers for interstage cooling of natural gas compression. The results of modernization were the reduction in energy consumption on 10-15% AGFCS per cubic meter of high pressure natural gas and improving reliability of compressor units. For expanding the scope of the AGFCS developed and integrated into its structure equipment for production liquefied natural gas (LNG). The created LNG complex was put into pilot industrial operation with a loading up to 20 hours a day. The complex capacity is 580-620 kg/h of LNG specific expenditure of energy 0,95-0,97 kWh/kg LNG.
