Development of new technological processes based on supersonic flow of natural gas

The article is devoted to the study of supersonic movement of natural gas in a pipeline and the possibility of developing new technological processes for cooling, drying and separating liquid hydrocarbons. Technological processes and a set of equipment created using the supersonic movement of natural gas are studied, their advantages and disadvantages are analyzed. It is known that a change in the process of gas injection into UGS facilities in a wide range of pressure during the season creates opportunities for more efficient use of compressor equipment. The thermobaric parameters of gas cooling due to supersonic motion in various designs have been calculated, and the existence of ample opportunities for creating new technological processes has been proved. Recommendations have been developed on the throughput capacity of gas installations to ensure the regulation of cooling systems created for underground gas storage facilities. It was noted that the cooling and gas separation systems created on the basis of thermobaric parameters and principles of regulation will be useful not only for underground gas storages, but also for other sub-sectors of the gas industry.
