Embodiment
[0035] An aromatics extraction device provided by the present invention is used in the process of hydrogenated gasoline extraction to produce benzene and toluene. The principle of aromatics extraction is essentially the extraction and fractionation of aromatics. The extraction agent used this time is The boiling point of sulfolane and sulfolane is 281°C under standard atmospheric pressure. The working pressure of this equipment is basically consistent with atmospheric pressure. The boiling point of each substance is similar to that under standard atmospheric pressure. The main products this time are benzene and toluene. It is 80.6°C under standard atmospheric pressure, and the boiling point of toluene is 110.6°C. In the subsequent fractionation process, it is necessary to rely on the difference in boiling point to improve the purity of the product. It should be noted that the liquid phase solution will not reach the boiling point in the natural state. Natural volatilization.

Abstract
The invention discloses an aromatic hydrocarbon extraction device and relates to the technical field of aromatic hydrocarbon extraction equipment. Including the equipment rack, the equipment rack includes two interconnected bottom mounting racks and top mounting racks. The solvent tank and extraction tank are respectively installed on the top of the top mounting rack, and the recovery tank and fractionation tank are respectively installed on the top of the bottom mounting rack. A feed pipe is fixedly connected, a feed pump is installed between the solvent tank and the extraction tank, and the suction end of the feed pump is connected to the bottom of the solvent tank through a pipeline. The present invention can adjust the temperature of the extractant in real time according to the change of the ambient temperature by setting the solvent tank with temperature adjustment function, so as to form a heat preservation interval between the set outer tank and the inner tank, and set a heating rod inside as a The source of heat, so that the extraction agent is kept at a suitable temperature during the extraction of the equipment to avoid the influence of the ambient temperature on the entire process. The solvent tank can effectively keep the internal extraction liquid warm to reduce energy consumption.
Description
technical field [0001] The invention relates to the technical field of aromatics extraction equipment, in particular to an aromatics extraction device. Background technique [0002] Aromatics extraction, also known as aromatics extraction, is the process of separating aromatics from hydrocarbon mixtures with extractants, mainly used to recover light aromatics (benzene, toluene, various xylenes) from catalytic reforming and hydrocarbon cracking steam, sometimes It is also used to recover naphthalene from catalytic cracking diesel oil, and the remaining non-aromatic hydrocarbons after extracting aromatics are called raffinate oil. Aromatic hydrocarbons are referred to as "aromatic hydrocarbons" for short, and generally refer to hydrocarbons containing a benzene ring structure in their molecules. [0003] The Chinese invention patent with the patent publication number CN108375549A discloses an extraction device and method for automatically separating petroleum components, whic...
