Problems solved by technology
[0007] The purpose of the present invention is to provide a distillation device for light aromatics, to solve the problem that the steam flow generated during the first and second stages of distillation is less than that generated during the middle stage, which cannot be effectively solved. The hydrogenation amount and catalyst amount are controlled according to the steam flow rate, and the light aromatic hydrocarbon mixture is a polycyclic hydrocarbon, and its liquid concentration is relatively high. When the steam is liquefied by using a condenser tube, the liquefied liquid is easy to adhere to the surface of the condenser tube, thus The formation of a liquid film makes the condensation effect of the condenser pipe worse

The invention discloses a distillation device for light aromatic hydrocarbon, and relates to the field of light aromatic hydrocarbon processing equipment. The distillation device comprises a rectifying tower, a feeding pipe, a boiler, a gas collecting hood, a gas conveying pipe, a connecting block, an outer sleeve and an inner sleeve; a partition plate is arranged in the rectifying tower, a gas outlet is formed in the center of the partition plate, and a sealing plate is arranged at the gas outlet; an air pressure lifting assembly is arranged at the bottom of the sealing plate, blades are arranged at the bottom of the sealing plate, a driving assembly is arranged at the top of the sealing plate, and a wall scraping assembly is arranged on the right side of the rectifying tower. According to the invention, the flow of steam generated during distillation can be conveniently controlled, so hydrogenation can be continuously carried out subsequently, and the hydrogenation content does not need to be controlled.
Description
technical field [0001] The invention relates to the field of light aromatics processing equipment, in particular to a distillation device for light aromatics. Background technique [0002] Light aromatics are a mixture of nine-carbon aromatics with complex components. There are two main sources of light aromatics, one is from the bottom oil of xylene in the reforming unit of the refinery, which is called reformed hydrocarbons; the other is from the by-products of ethylene production , contains a large amount of unsaturated components, and light aromatics account for about 80% of cracked heavy aromatics. In recent years, with the rapid development of petrochemical industry, especially the improvement of ethylene production capacity, the output of cracked hydrocarbons has continued to increase. How to Making full and reasonable use of this part of resources to produce the best economic benefits will have a major impact on the overall efficiency of ethylene plants and the devel...
