Description

Technical Field

[0001] The invention belongs to the technical field of tar conversion, and in particular relates to a device for producing aromatics by directional conversion of tar. Background Art

[0002] With the rapid improvement of chemical production technology, the market demand for synthetic fibers such as polyester, polyethylene and polycarbonate continues to grow at home and abroad, and the demand for basic chemical raw materials such as light aromatics BTX (benzene, toluene, xylene) continues to grow. Coal tar is one of the liquid products obtained from coal distillation and gasification. At room temperature, it is a black or dark brown viscous liquid with a pungent odor. It is mainly composed of polycyclic aromatic compounds. The composition of coal tar is extremely complex. According to the different cracking temperatures, it can be divided into several different products such as low-temperature coal tar, medium-temperature coal tar and high-temperature coal tar. By processing coal tar through hydrogenation, high-value-added low-sulfur naphtha and clean fuel oil can be obtained, realizing the cleanliness and lightness of coal tar. In addition to using coal tar hydrogenation technology to produce oil products, how to efficiently convert aromatics in coal tar is an effective way for refineries to tap potential and increase efficiency.

[0003] In the existing tar conversion process, the aromatic hydrocarbons in the tar are vaporized by heating, and then the vaporized aromatic hydrocarbons are converted into liquid by condensation, so as to quickly obtain aromatic hydrocarbons. However, since the untreated tar contains a large amount of impurities, the quality of the aromatic hydrocarbons extracted subsequently is greatly reduced, which greatly reduces the quality of the aromatic hydrocarbons and requires secondary treatment. Therefore, we provide a tar directional conversion to aromatic hydrocarbons device. Summary of the invention

The separated tar is transported to the interior of the multi-stage filter box 3 through the No. 1 oil guide pipe 9. When the tar contacts the filter membrane plate 12, the solid impurities in the tar are filtered through the filter membrane plate 12, and the tar is transported to the inner cavity of the conversion box 1 through the No. 2 oil guide pipe 13, thereby achieving the purpose of filtration.

[0029] See Figure 1 and Figure 3As shown, the mixing barrel 4 and the multi-stage filter box 3 are connected through a No. 1 oil guide pipe 9, and a No. 1 control valve 10 is provided on the surface of the No. 1 oil guide pipe 9.

[0030] When in use, firstly, the external ammonia is transported to the inner cavity of the outer box 20 through the gas pipe 29, and the temperature of the inner cavity of the outer box 20 is lowered by utilizing the characteristics of ammonia. Similarly, when the temperature inside the outer box 20 is lowered, the temperature inside the inner box 21 will also be lowered. Secondly, the tar is transported to the inner cavity of the mixing barrel 4 through the oil pipe 5. During the transportation process, the NiWγAl2O3 catalyst is also transported to the inner cavity of the mixing barrel 4 through the feed port on the top of the surface of the mixing barrel 4. After the transportation is completed, the No. 1 motor 6 is started, and the No. 1 motor 6 converts electrical energy into mechanical energy, and drives the No. 1 rotating rod 7 to rotate, and the No. 1 rotating rod 7 drives the spiral stirring blade 8 to rotate.

When the tar and the NiWγAl2O3 catalyst are completely mixed, the characteristics of the NiWγAl2O3 catalyst can be used to convert the sulfur and nitrogen in the tar into an easily removable form (such as solid), thereby achieving the purpose of separation. Then, the No. 1 control valve 10 and the No. 2 control valve 14 are turned to make the No. 1 oil guide pipe 9 and the No. 2 oil guide pipe 13 in a cleared state, and then the tar can be transported to the inside of the multi-stage filter box 3 through the No. 1 oil guide pipe 9. When the tar and the filter membrane When the plate 12 contacts, the solid impurities in the tar are filtered through the filter membrane plate 12, and the tar is transported to the inner cavity of the conversion box 1 through the No. 2 oil guide pipe 13, so as to achieve the purpose of filtering and improve the cleanliness of the tar. Finally, the heating plate 28 is started, and the electric energy is converted into thermal energy through the heating plate 28, and the heat is transferred to the surface of the shell 27 through a heat-conducting material such as an aluminum alloy or stainless steel, and further transferred to the surface of the conversion box 1, so as to increase the temperature of the inner cavity of the conversion box 1. In this process, the No. 2 motor 15 is started, and the No. 2 rotating rod 16 is driven to rotate by the No. 2 motor 15, and the rectangular stirring blade 17 is driven to rotate by the No. 2 rotating rod 16, and the The tar is stirred by the rectangular stirring blades 17 so that the tar is heated evenly to prevent local heating. During the heating process, the aromatic hydrocarbons in the tar are vaporized and transported to the inside of the inner box 21 through the air outlet pipe 18. Since a one-way air outlet valve 19 is provided on the surface of the air outlet pipe 18, the characteristics of the one-way air outlet valve 19 are utilized to prevent the vaporized aromatic hydrocarbons from flowing back, thereby achieving the purpose of directional transportation. Since the temperature inside the outer box 20 is relatively low, the vaporized aromatic hydrocarbons are condensed, and the vaporized aromatic hydrocarbons are converted into liquid and fall into the inside of the collecting box 22. The liquid aromatic hydrocarbons are collected by the collecting box 22 to facilitate subsequent unified processing.
