Definitions
- the invention relates to the field of oil refining, in particular, to a delayed coking process to produce coke with a volatile content of 15-25% for use as a coking additive in a coal coking charge in the production of metallurgical coke.
- Petroleum coke with a volatile matter content of more than 14% and less than 25% makes it possible not only to replace the K grade coke coal (coking) for introducing coal coking into the charge, but also to improve the quality of metallurgical coke obtained (Pat. RF JY O 2355729, ⁇ 10 ⁇ 57 / 04 , published on May 20, 2009).
- a known method of producing petroleum coke by delayed coking of the oil residue including heating the feedstock in a tubular furnace to 490 - 515 ° C, mixing the feedstock with recirculated by distillate coking products formed in the coking chamber in a distillation column with the formation of distillation residue, the supply of secondary raw materials - bottoms the remainder in the coking chamber with a temperature of 485-495 ° C and coking with the formation of coke.
- the disadvantage of this method is that as a result of coking get high strength coke with a low content of volatile substances (up to 9%) of the mass).
- Closest to the claimed object is a method of delayed coking of oil residue, including heating the feedstock to 340-380 ° C, mixing it with recirculate heavy coking gas oil (pyrolysis resin, heavy catalytic cracking gas oil) in a mixing tank to form secondary raw materials, heating the secondary raw materials obtained in the mixing tank of the heavy residue and fed into the coking chamber with a temperature of 485-505 ° C, coking with the formation of coke (Pat. RF N ° 2206595, class C 10B 55/00, publ. 20.06.2003).
- heavy coking gas oil pyrolysis resin, heavy catalytic cracking gas oil
- the disadvantage of this method is the low content of volatiles in the obtained coke due to the high coking temperature (485-505 ° C), as well as low productivity due to intensive foaming and, as a result, the inability to more fully use the volume of the coking chamber.
- the invention is aimed at increasing the content of volatile substances in coke and increasing the productivity of the installation.
- the secondary raw materials are fed into the coking chamber with a temperature of 455-470 ° C.
- an anti-foam additive is fed into the coking chamber.
- the antifoam additive is fed to two or four points along the perimeter of the coking chamber in order to completely cover the surface of the foam.
- the implementation of the coking process at low temperatures due to the supply of raw materials at the inlet of the coking chamber with a low temperature will allow to obtain coke with a volatile content of 15-25% for use as a coking additive.
- the supply of antifoam additives during the last 3-5 hours before the coking process is completed will not only reduce the level of foam in the coking chamber, but will also increase the productivity of the feedstock process.
- the drawing shows a schematic diagram of an installation for implementing the proposed method for producing coking additives delayed coking.
- the proposed method for producing coking additives delayed coking is as follows.
- the feedstock which can be used as tar, deasphalting asphalt, oil extracts, heavy catalytic cracking gas oils or mixtures thereof in any proportions, is heated in a tube furnace 1 to a temperature of 270 - 350 ° C and fed into a mixing tank 2 connected by vapors with distillation column 3.
- Heavy coking gas oil, withdrawn from distillation column 3 in the form of a side stream, is fed into the same container as a recirculate.
- the resulting secondary raw material obtained by mixing the primary raw material with recirculated material is heated in a tube furnace 4 and fed to alternating coking chambers 5 with a temperature of 455-470 ° C, where the resulting coking agent accumulates, the additive with a volatile content of 15-25%.
- the distillate coking products formed in the coking chamber 5 are fed to a distillation column 3 for separation into gas, gasoline, light and heavy coking gas oils and bottoms. Vaporous products leave on top of distillation column 3, light and heavy gas oils are removed from its middle part, and bottom residue is withdrawn from the bottom.
- an anti-foam additive 6 is fed into the coking chamber 5 at four points around the perimeter of the chamber.
- the proposed method is illustrated by examples 1 - 4.
- coking of a mixture of raw materials consisting of a vacuum residue of visbreaking, tar and heavy gas oil of catalytic cracking in the ratio of 15:75: 10 was carried out.
- the raw material has a density of 1.055 g / cm3, coking 25.8% and a sulfur content of 3.8%.
- the primary raw material was heated in the convection section of the furnace to a temperature of 320 ° C and mixed in a mixing tank with recirculate - heavy coking gas oil, removed from the distillation column in the form of a side stream.
- the resulting secondary raw material was heated in a tube furnace and fed into a coking chamber to obtain a coking additive.
- the coke was steamed with water vapor, cooled with water and discharged hydraulically.
- examples 2 and 4 to prevent foaming in the coking chamber 4 hours before the end of coking, an antifoam additive was applied.
- the mode and results of coking in examples 1 to 4 are summarized in table.
- coking of the same raw materials was carried out as in examples 1-4, according to the prototype, with a secondary feed temperature at the entrance to the coking chamber 485 ° C without anti-foam additives.
- the result was a conventional electrode coke with a volatile content of 10.8%.
- the mode and results of coking are summarized in the same table.
- the proposed coking method will allow to obtain coke for use as a coking additive with a volatile content of more fifteen %.
- the supply of raw materials to a chamber with a temperature below 456 ° C is impractical, since a bituminous mass may form in the upper part of the coking chamber, which causes difficulties for steaming and cooling the coke.
- raw materials are supplied above a temperature of 470 ° C, coke is formed with a volatile matter content of less than 15%.
- the supply of antifoam additives to the upper part of the coking chamber will reduce the level of foam formed during the coking process, which will increase the productivity of the method for feedstock.
