Using vortex tube for decreasing losses of natural gas in engineering systems of gas supply

“…The geometric dimensions of the vortex tube depend on the amount of natural gas passing through it. Therefore, it is expedient to use it at automated gas distribution stations of the AGDS 1/3, AGDS-3 or block GDSs with the productivity until to 2500 m 3 Lvivtransgaz operates 213 gas distribution stations [13] and Ukrtransgas operates 1455 gas distribution stations [10]. 1/3 of the gas distribution stations operated by Lvivtransgas have a productivity of up to 2500 m 3 /hour, and therefore they can use the vortex tube for heating natural gas before the throttling process.…”

“…In the structure of the total consumption of primary energy in Ukraine, its share is about 37%. Each year, Ukraine consumes about 31 billion m 3 of natural gas, of which it imports more than 11 billion m 3 . For energy independence of Ukraine it is necessary to reduce natural gas consumption.…”

“…There are several ways to reduce natural gas consumption. For example, thermo-modernization of existing residential buildings [1], [2], [3] the use of alternative fuels, in particular biogas [4] and reduction of natural gas losses directly in engineering systems of gas supply. Annual losses of natural gas in engineering systems of gas…”
