A method for distributed production of liquefied natural gas at gas-distribution stations

详细

The operating conditions of gas-distribution stations located on gas-main pipelines are analyzed. It is shown that there is a technological pressure difference in natural gas at most stations, which can be used for liquefaction of natural gases. The data of the numerical investigation, demonstrating that it is possible to abandon the use of flame heaters of reduced natural gas due to the use of the gasdynamic energy separation effect by simultaneously cooling the natural gas going to liquefaction, are given. This technique can be applied on a quarter of all gas-distribution stations of the Russian Federation (about 1000 stations).
