Description

Technical Field

[0001] The utility model relates to the technical field of benzene desulfurization devices, in particular to a benzene desulfurization device. Background Art

[0002] The benzene desulfurization device is a device used to remove hydrogen sulfide from benzene. When the benzene gas passes through the desulfurization tower, it comes into contact with a liquid containing an alkaline solution. Under alkaline conditions, hydrogen sulfide is converted into an ion state and is easily dissolved in water. Hydrogen sulfide is absorbed from the benzene gas into the alkaline solution. During the absorption process, hydrogen sulfide reacts with sodium hydroxide in the alkaline solution to generate sodium sulfide, which accumulates in the solution. Then, the sodium sulfide is regularly removed from the solution or converted into other chemicals to ensure the continuous operation of the desulfurization device.

[0003] When benzene gas passes through the desulfurization tower, it comes into contact with the alkaline solution in the tower. Hydrogen sulfide will be absorbed from the benzene gas into the alkaline solution and react with the sodium hydroxide in the solution to form sodium sulfide, effectively removing hydrogen sulfide from the benzene. When the benzene gas enters the desulfurization tower, the benzene gas is concentrated into a stream and flows into the interior of the desulfurization tower, which can easily cause the alkaline solution in some areas to be overloaded, thereby reducing the desulfurization effect. Therefore, we proposed a benzene desulfurization device. Utility Model Content
