PRODUCTION METHOD OF DIESEL FUEL WITH LOW-TEMPERATURE PROPERTIES, AND PLANT FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC F02M43/00 C10L1/08 C10G55/08 

FIELD: machine building.

SUBSTANCE: depression additives are introduced to pre-heated fuel before it is delivered under action of centrifugal forces in a vortex unit, and after it is delivered under action of centrifugal forces in the vortex unit, aviation kerosene is added to mixture of fuel with depression additives before fuel is supplied to consumers. A plant for production of diesel fuel with low-temperature properties, which contains the main fuel line having an inlet part for connection with an original fuel source, a middle part with the vortex unit, and an outlet part for connection to a storage tank of ready diesel fuel, as well as a supply tank with depression additive, which is interconnected through a batch metre with the main fuel line, which differs by the fact that it includes the first and the second pumps, an aviation kerosene tank and a heating belt enveloping the inlet part of fuel main line. The vortex unit is made in the form of a vortex heat generator; inlet part of the fuel main line is connected to its middle part through the first pump; the aviation kerosene tank is connected through the second pump to the middle part of the main fuel line at the vortex heat generator outlet, and the batch metre is interconnected with the fuel main line in its middle part between the first pump and the vortex heat generator inlet.

EFFECT: use of the method and the industrial plant will allow obtaining winter diesel fuel from summer diesel fuel with improved low-temperature properties, with stable consumer properties and long-term storage period.
