Abstract

FIELD: oil refinery, jet fuel production from oil. SUBSTANCE: method provides for electrical demineralization of different oils in electrical dehydrator with system of electrodes located in two levels with gradient of height between them - 0.05 - 0.1 of conventional section of way coinciding with medium vector of oil stream motion in maximum midsection zone. In the case oil stream after demineralization is fed in atmospheric distillation tower with pack of nozzles and two branch pipes tangentially located in body of tower, that has inner cylindrical reflector of stream, diameter of which is in ratio to diameter of body in zone of feeding as (0.59 - 0.75) : 1 and height range of oil streams introduction is equal to (0.21 - 0.28) of tower height from low side of tower bottom. Separation of 140 - 240 C kerosene fraction is exercised in height interval of tower and separated kerosene fraction is divided for three flows. Third flow in mixture with 30 - 35 % mass of residual kerosene fraction after second distillation of gasoline is delivered to hydraulic purification and produced product is introduced with 0.007 - 0.008 % mass of concentrate of naftenic acids and ionol dopes mixture. Diesel fraction is fed into lixiviation block, in which straight distilled kerosene fraction is fed. Aimed diesel fuel is produced by compounding of diesel fraction separated from lixiviation block and from fractions, separated on different stages of process. EFFECT: improved diesel and jet fuel production processes. 63 cl, 6 dwg, 1 tbl

Изобретение относится к нефтепереработке, в частности к способу получения дизельного и реактивного топлива из нефти. Сущность изобретения состоит в электрообессоливании различных нефтей в электродегидраторе с системой электродов, расположенных в двух уровнях, при градиенте высоты между ними 0,05-0,1 условного отрезка пути, совпадающего со средним вектором перемещения потока нефти в зоне наибольшего миделя, при этом поток нефти после обессоливания поступает в колонну атмосферной перегонки с пакетом насадок и двумя патрубками, тангенциально расположенными в корпусе колонны, снабженной внутренним цилиндрическим отражателем потока, диаметр которого соотносится с диаметром корпуса в зоне питания как (0,59-0,75):1, а высотный диапазон ввода потоков нефти составляет 0,21-0,28 высоты колонны от низа днища колонны, причем вывод керосиновой фракции 140-240°С ведут в высотном интервале колонны, составляющем 0,58-0,81, считая от низа днища колонны, а выделенную керосиновую фракцию делят на 3 потока, третий поток в смеси с 30-35 мас.% остаточной керосиновой фракции после вторичной перегонки бензина подают на гидроочистку и в полученный продукт вводят 0,007-0,008 мас.% концентрата смеси присадок нафтеновых кислот и ионола , при этом дизельную фракцию подают на блок защелачивания, куда направляют также прямогонную керосиновую фракцию, и целевое дизельное топливо получают компаундированием дизельной фракции, отводимой из блока защелачивания и фракций, отводимых с различных стадий процесса. 63 з.п. ф-лы, 6 ил.The invention relates to oil refining, in particular to a method for producing diesel and jet fuel from oil. The essence of the invention consists in the electrical desalination of various oils in an electric dehydrator with a system of electrodes located at two levels, with a height gradient between them of 0.05-0.1 conventional section of the path, which coincides with the average vector of movement of the oil flow in the zone of the greatest midsection, while the oil flow after desalination, it enters the atmospheric distillation column with a nozzle package and two nozzles tangentially located in the column body equipped with an internal cylindrical flow reflector, the diameter of which is worn with a case diameter in the feed zone as (0.59-0.75): 1, and the altitude range for introducing oil flows is 0.21-0.28 the height of the column from the bottom of the bottom of the column, and the output of the kerosene fraction is 140-240 ° C lead in the altitude range of the column, 0.58-0.81, counting from the bottom of the bottom of the column, and the extracted kerosene fraction is divided into 3 streams, the third stream in a mixture with 30-35 wt.% residual kerosene fraction after the secondary distillation of gasoline is fed to hydrotreating and 0.007-0.008 wt.% of a concentrate of a mixture of additives of naphthenic acids and ionol are introduced into the resulting product, in this case, the diesel fraction is fed to the alkalization unit, where the straight-run kerosene fraction is also sent, and the target diesel fuel is obtained by compounding the diesel fraction removed from the alkalization unit and fractions withdrawn from various stages of the process. 63 s.p. f-ly, 6 ill.
