Naphtha deep desulfurization device

Abstract

The invention belongs to the field of naphtha processing, particularly relates to a naphtha deep desulfurization device, and provides the following scheme aiming at the problems that naphtha cannot be deeply desulfurized and the desulfurization index cannot reach the standard due to the fact that existing desulfurization equipment is not thoroughly reacted with a desulfurizer in the desulfurization process. The device comprises a desulfurization treatment barrel, two delivery pumps, a control rod, a servo motor, a plurality of swing rods, a rotary driving mechanism and a plurality of deep mixing mechanisms; the two delivery pumps are fixedly connected to the outer side wall of the desulfurization treatment barrel, a mounting hole is formed in the bottom of the desulfurization treatment barrel, the control rod is mounted in the mounting hole, the servo motor is fixedly mounted at the bottom of the desulfurization treatment barrel, and an output shaft of the servo motor is rigidly connected with the bottom end of the control rod. The desulfurization device disclosed by the invention is high in contact efficiency with a desulfurizer in a desulfurization process, relatively thorough in reaction and capable of deeply desulfurizing naphtha, and desulfurization can meet 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
