METHOD OF THE NATURAL GAS LIQUEFACTION AT THE MOTORCAR GAS FILLING AND COMPRESSION STATION Russian patent published in 2007 - IPC F25J1/02 

FIELD: natural gas industry; motor car industry; methods of the natural gas liquefaction at the motorcar gas filling and compression stations.

SUBSTANCE: the invention is pertaining to the cryogenic engineering, in particular, to the methods of the natural gas liquefaction. The method of the natural-gas liquefaction, predominantly for the motor car liquid gas filling and compression stations is realized with usage of the technologically closed throttling recuperative cycle with the additional external chilling. The minimal pressure up to which the throttling of the gas takes place in the cycle is maintained at the level of no less than 0.4 MPa with the observance of the principle of ensured provision of the level of the carbon dioxide dissolubility in the produced liquefied natural gas at the set pressure exceeding the value of its maximum contents in the natural gas delivered for the liquefaction. The technical result of the invention is the increased productivity, reliability and profitability of the natural gas liquefaction process at the motorcar gas filling and compression stations.

EFFECT: the invention ensures the increased productivity, reliability and profitability of the natural gas liquefaction process at the motorcar gas filling and compression stations.
