TECHNOLOGICAL COMPLEX FOR PRODUCING GASOLINE OF EURO STANDARDS

摘要

The invention relates to the field of oil refining, in particular, to installations for the production of high eco-friendly gasoline, corresponding to modern ecological requirements EURO standards, without the use of processes of deep processing of oil, but with the maximum use of the resources of virgin petrol fractions of oil to produce gasoline with a low benzene content, and it can be applied to oil refineries, petrochemical and other industries. The technical result consists in simplifying the process for production of gasoline and not more than 0.4% to ensure receipt of the latter with a concentration of benzene., While providing the rest of the parameters corresponding EURO standards. SUMMARY: Complex 1 comprises a feed assembly (oil), setting 2 of primary processing it to obtain a wide straight-run gasoline fractions, secondary distillation unit 3, configured to separate the general straight-run gasoline fraction into three fractions boiling in the temperature range: light NK .-65 ° C, average 65-105 ° C and a heavy 105-180 ° C K.K. The block 3 is provided with lines 4 and 5 and easy removal of the middle fraction into individual prefabricated receptacle 6 and 7, respectively, and a line 8 to the heavy fraction outlet 9 catalytic reforming unit. Block 9 comprises a number of serially connected reactors 10-13, the first of which is a hydrotreating unit 10 and configured to perform a hydrotreating the heavy fraction of sulfur, and the subsequent 11-13 - for catalytic reforming of said fractions (filled with a catalyst, e.g., aljumoplatinovyh ). All reactors are connected in series with each other by means of conduits fitted with the heaters 14-16, e.g., tubular furnaces. Last unit 17, performs the function of a stabilization column 18 is provided with a pipe output from the top of the light ends column, a column with a bottom outlet 19 O debutanized gasoline reformer, coupled to a conduit 20 through tank 21 to one input container 22 for mixing. The other inputs of said container 22 are connected by pipelines 23, 24 and 25 respectively with the collecting container 6 for the light fraction from the collecting container 7, the middle fraction and the block 26 deliveries antidetonatornoy high-octane additives. The flight lines 20, 23-25 ​​are provided with adjustment units 27, adapted to feed on these pipelines 20, 23, 24 of these fractions in the mixing tank in an amount of 33-40 pbw light fraction NK-65 ° C, 15 -25 mass.ch middle fraction 65-105 ° C and 35-52 parts by weight debutanized reformulated gasoline obtained by catalytic reforming, the heavy fraction 105-180 ° C K.K. Wherein the weight of the mixture of these components in the mixing vessel should be equal to 100 parts by weight Output of said mixing container 22 is connected to the park 28 marketable product - EURO standard gasoline. 1 bp f-ly; 6 ZP f-ly; Table 1; 1 yl.
