Description

Technical Field

[0001] The present application relates to the field of desulfurization devices, and in particular to a petroleum desulfurization device. Background Art

[0002] In the process of petroleum refining, liquefied petroleum gas (LPG) produced by coking, atmospheric and vacuum, catalytic cracking and other units contains a large amount of sulfides, which can cause poisoning and deactivation of catalysts in subsequent processing. Elemental sulfur and hydrogen sulfide are highly corrosive to pipelines and storage containers. When used as civilian fuel, they will generate SOx, pollute the environment, and form acid rain.

[0003] The desulfurization process of liquefied gas is carried out in a desulfurization tower. A spray mechanism is installed in the desulfurization tower. The spray mechanism sprays alkali solution. The alkali solution moves downward and absorbs the sulfur in the petroleum liquefied gas, thereby achieving the purpose of filtering sulfides. However, after the liquefied petroleum gas enters the desulfurization tower, it will flow upward, so that the liquefied petroleum gas stays in the desulfurization tower for a shorter time, thereby shortening the contact time between the liquefied petroleum gas and the alkali solution, resulting in poor sulfide absorption effect. For this reason, we propose a petroleum desulfurization device. Utility Model Content
