From the 25th plate of a column of K-2 the component of diesel fuel is removed and arrives on the top plate of striping-column K-3b. Column bottom temperature no more than 300 With, pressure no more than 4,5 kg / see Couples from K-3b come back to K-2 under the 26th plate, and the component of diesel fuel gets the pumps N-19 or N-20, the air HV-4 refrigerator is pumped over via T-3/1 and T-2/3 heat exchangers where gives heat of oil, and goes to reservoir park with a temperature not higher than 60 Pages.
From K-2 fuel oil gets the pump N-28 or N-29, is pumped over via the adjusting valve which regulirnut level in K-2, via the T-4/2 heat exchanger and further goes to HV-11 and H-11 refrigerators to cooling and then goes tanks.
1 - case; 2,6,11 - plates valvate direct-flow respectively three, two - and four-line; 3 - assembly union; 4 - a plate for collecting and a conclusion of a phlegm; 5, 8 - plates mesh with otboyny elements respectively two - and one-line; 7 - a plate for collecting a phlegm with mesh chippers; 9 - chipper mesh; 10 - ulita of input of raw materials; 12 - collector of distribution of water vapor
Vapors of hydrocarbons from above of a column of VK-1 come on two shlemovy lines to the barometric BK-1 condenser having 7 cross plates. For condensation of parovuglevodorod and absorption of gases of decomposition recirculation vacuum distillate is used.
Couples from K-3a on the pipeline come back to K-2 column under the 16th plate. From bottom K-3a the heavy component of summer diesel fuel gets the pumps N-17 or N-18, is pumped over via T-6/1 and T-6/2 heat exchangers where gives heat of oil, via air HV-7 refrigerators and goes to reservoir park with a temperature not higher than 60 Pages.
The 1st circular irrigation gets from a pocket of 32 plates of K-2 the pumps N-14 or N-15, is pumped over via the T-5 heat exchanger, the air XB-5/1,2 refrigerator and comes back to K-2 column to the 34th plate.
From a bottom of a vacuum column of VK-1 tar with a temperature not higher than 400 With arrives on reception of the pumps N-36, 37, 38 and one of them goes to the T-9/1,2 heat exchanger where it is cooled 6 having given warmly to the first stream of oil, then the part it goes to the H-1 refrigerator
Gas from the reflyuksorny capacity of E-1 comes together with fuel gas from a factory network to G-1 gas-chipper, from where through a heater of T-19 goes to torches of P-1, P-2, P-furnaces Liquid from G-1 is pumped out by the pumps N-12 or N-13 in a petrol settler of E-
At the exit from installation the general stream of a heavy component of summer diesel fuel is divided into two streams: on one ptok diesel fuel goes to tanks of shop 8, on another - to tanks of shop
Updating of the vacuum distillate recirculating on the closed cycle and the decomposition of fuel oil which is sated with light hydrocarbons and products happens due to feed of the top or average vacuum fractions. Surplus of a retsirkulyat is pumped out to the line of vacuum gasoil via the valve regulating level in E-20a. The expense of a retsirkulyat in Bk-1 is regulated by the valve. The expense of giving is regulated in BK-1 - not less 40m3/hour.
From the 15th plate of a column of K-2 the heavy component of summer diesel fuel in striping-column K-3a is removed, bottom which temperature no more than 350 With, pressure is not higher than 4,5 kg / see the Conclusion of lateral shoulder straps of a column of K-2 is carried out on the fixed exit of fractions on material balance.
The 1st circulating irrigation gets from a pocket of 22 plates of K-2 the pumps N-16 or N-15, is pumped over via T-1/1 and T-1/2 heat exchangers where gives heat of oil, via the HV-6 air coolers and comes back to a column To - On an entrance to K-2 column the stream of a circulating irrigation is divided into two streams: one stream moves on the 24th plate as the 2nd TsO, and the second stream on the 14th plate in a kachesta of the 3rd TsO.
The first potok:prokhodit four couples heat exchangers. In T-1/1 and T-132 heat exchangers oil heats up due to heat of the second circulating irrigation of an atmospheric column; in T-9/1 and T-9/2 oil heats up due to heat output from installations of fuel oil or tar.
