A device for deep desulfurization of naphtha

Abstract

The invention belongs to the field of naphtha processing, in particular to a device for deep desulfurization of naphtha, aiming at the incomplete reaction of existing desulfurization equipment with desulfurizers during the desulfurization process, resulting in the inability to deeply desulfurize naphtha, and the desulfurization index cannot For the problem of reaching the standard, the following plan is proposed, which includes a desulfurization treatment barrel, two transfer pumps, a control rod, a servo motor, several swing rods, a rotary drive mechanism and several deep mixing mechanisms, and the two transfer pumps are fixedly connected On the outer wall of the desulfurization treatment barrel, the bottom of the desulfurization treatment barrel is provided with a mounting hole, the control rod is installed in the installation hole, the servo motor is fixedly installed on the bottom of the desulfurization treatment barrel, and the output of the servo motor The shaft is rigidly connected to the bottom end of the control rod. The desulfurization equipment of the present invention has high contact efficiency with the desulfurizer in the desulfurization process, and the reaction is relatively thorough, and can deeply desulfurize the naphtha, and the desulfurization can meet the requirements.

Description

technical field [0001] The invention relates to the technical field of naphtha processing, in particular to a device for deep desulfurization of naphtha. Background technique [0002] Naphtha is one of petroleum products. It is light oil used for chemical raw materials produced by processing crude oil or other raw materials. It is mainly used as reforming and chemical raw materials. There are various distillation ranges due to different uses. It is used for the production of aromatics. When reforming raw materials, use 70°C~145°C distillate, which is called light naphtha, and when the purpose is to produce high-octane gasoline, use 70°C~180°C distillate, weigh naphtha, and use When used as a solvent, it is called solvent naphtha. Aromatic solvents from coal tar are also called naphtha or solvent naphtha. With the improvement of environmental protection requirements, only monoalkane solvents, aromatics, low-sulfur Naphtha, a blending component of gasoline, is favored by the ...

Aromatic solvents from coal tar are also called naphtha or solvent naphtha. With the improvement of environmental protection requirements, only monoalkane solvents, aromatics, low-sulfur Naphtha, a blending component of gasoline, is favored by the market. Naphtha needs to be desulfurized during the processing process. However, the existing desulfurization equipment does not react thoroughly with the desulfurizer during the desulfurization process, resulting in the inability to deeply desulfurize the naphtha. , the desulfurization index cannot reach the standard
