METHOD OF PRODUCTION OF WHITE PETROLEUM DERIVATIVES Russian patent published in 1995 - IPC

FIELD: petroleum chemistry. SUBSTANCE: petroleum with different content of sulfur is subjected to demineralization in electric dehydrators, the level of electrodes in which overlaps their height range in the upper half of the body, and the height gradient between the electrode levels on the path of the petroleum ascending current equals 0.05 to 0.1 of the relative path section coinciding with the mean vector of petroleum current in the zone of the maximum midsection of the electric dehydrator covered by the current during 1 hour of movement at an average process rate, then petroleum is subjected to distillation, including in the atmospheric column provided with packs of cross-flow nozzles. Petroleum is fed to the column through branch pipes tangentially arranged in the column body in the feed zone. The latter is provided with an internal cylindrical current deflector, whose diameter matches up with the body diameter as (0.95-0.75) to 1. The height range of the petroleum currents inlet equals 0.21 to 0.28 of the column height. Withdrawal of the kerosine and diesel fractions is effected in the column height range equal to 0.58-0.81 and 0.32-0.62 of its height respectively, 0.51-0.61 of stable petrol fraction is subjected to redistillation. 80 to 180 C fraction is subjected to reforming. A concentrate of additive is added to the product of hydrofining of the mixture of straight-run distillation kerosine fraction and residual fraction of redistillation to obtain jet fuel. Diesel fuel is obtained by alkanization in two stages with the use of an injector and mother liquor and subsequent blending of diesel fraction with straight-run distillation kerosine and/or the last one after hydrofining. EFFECT: facilitated procedure. 81 cl, 1 tbl, 6 dwg
