DEVICE FOR LIQUEFACTION OF NATURAL GAS Russian patent published in 2016 - IPC F25J1/00 

FIELD: oil and gas industry.

SUBSTANCE: invention can be used for the liquefaction of natural gas and associated gas utilization by liquefaction. Apparatus comprises a gas supply line, the three lines of the vortex tube with outlet partially heated and cooled gas, which are interconnected in cascade through the chilled gas. It also includes heat exchangers, line removal, and the capacity of liquefied natural gas condensate. Heat exchangers are located on the lines of the hot gas outlet part of the first two vortex tubes. On the lines of the cooled gas outlet of the vortex tubes mounted chokes, and line tap part of the heated gas vortex tubes are connected to the input of the first vortex tube. Thus the first two vortex tubes equipped with the separation units, which are equipped with exhaust gas lines and removal lines solids connected to the tank collection of solids.

EFFECT: technical result is to reduce the size and weight of the device, ensuring optimum cooling.
