NATURAL GAS LIQUEFACTION DEVICE AND METHOD FOR THE REALIZATION THEROF Russian patent published in 2021 - IPC F25J1/00 F25B9/04 

FIELD: gas industry.

SUBSTANCE: invention relates to the gas liquefaction and can be used in gas distribution stations. The device for natural gas liquefaction comprises a heat exchanger and a vortex cooler which are arranged in a two-sectional separator container. A vortex cooler chamber with a cold end is arranged in the lower section and is connected to a central pipe being the heat exchanger core, in which tubes are vertically arranged. There is a hollow space between the horizontal barrier and the top tube board, in which there is a vortex chamber with an inlet pipe connecting said chamber to the interpipe space of the heat exchanger. A hot end is arranged in the upper section and is enclosed in a cylindrospheric sleeve installed on a horizontal barrier. The horizontal barrier has throttle diaphragm apertures with an outlet into the lower hollow space. A separation device is arranged in the upper section of the cylindrospheric sleeve. A shut-off and control valve and a low-pressure gas discharge pipe are installed outside the upper section of the separator tank. An outlet pipe is arranged in the cubic part of the liquefied product gas collector.

EFFECT: technical result consists in increasing efficiency of natural gas liquefaction.
