The invention relates to oil refining and can be used in production of low-sulfur diesel fuel which is being increasingly used in Russia and Europe.
[0005] The projected fuel demand in Europe (" " [Oil and Gas Technology] magazine, No. 6, 2007, p. 94) indicates increasing production of diesel fuel and decreasing production of gasoline:
TABLE-US-00001 2005 2010 2015 2020 Gasoline, million ton/year 137.0 128.3 127.0 131.0 Diesel fuel, million ton/year 201.2 237.8 251.8 251.5
[0006] Dieselization of vehicular transport is due to the fact that a diesel engine is 25-30% more cost effective than a gasoline one.

012] According to the method described in the RF patent No. 2387700, after oil is demineralized it is distilled. Here, diesel fraction with a 171-341° C. boiling temperature is extracted from an atmospheric tower. Fractions with a boiling temperature above 341° C. together with fuel oil are fed to a vacuum column for further refining. Fractions with a 181-304° C. and 226-326° C. boiling temperature are extracted from a vacuum column and mixed with diesel fraction from the atmospheric tower while maintaining a balance ratio, wherein the end boiling point (EBP) of the balanced mixture of these fractions, when refined using the ASTM D-86 method, does not exceed 340° C. The mixture is hydrogen refined, producing low-sulfur diesel fuel with a sulfur content no higher than 10 ppm. The technical result is that the method per the invention makes it possible to produce diesel fuel with a sulfur content no higher than 10 ppm.
