METHOD OF PRODUCTION OF JET FUEL Russian patent published in 1995 - IPC

FIELD: petroleum refining. SUBSTANCE: invention consists in electric demineralization of various petroleums in an electric dehydrator with a system of electrodes located at two levels, the height gradient between them being within 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. After demineralization the petroleum current is fed to the atmospheric distillation column with a pack of nozzles and two branch pipes tangentially arranged in the column body. The column is provided with an internal cylindrical current deflector, whose diameter matches up with the body diameter in the feed zone as (0.59 - 0.75) to 1, and the height range of the petroleum currents inlet makes up 0,.21 to 0.28 of the column height from the column bottom base. Withdrawal of kerosine fraction at 140 to 240 C is conducted in the column height range equal to (0.58-0.81) counting from the column bottom base. The extracted kerosine fraction is divided into 3 currents, the third current in the mixture with 30 to 35 percent by mass of the residual kerosine fraction after petrol redistillation is fed to hydrofining. O.007 to 0.008 per cent by mass concentrate of a mixture of additives of naphthenic acids and ionol is introduced into the obtained product. EFFECT: facilitated procedure. 33 cl, 1 tbl, 6 dwg
