Description

Technical Field

[0001] The invention relates to the technical field of coke oven gas treatment, and in particular to a coke oven gas desulfurization tower. Background Art

[0002] The coke oven gas produced in the process of oil refining 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 can pollute the environment and form acid rain. Therefore, desulfurization of coke oven gas is an essential process in the process of oil refining.
