Precise desulfurization of coke oven gas
Thread Content
At present, after purification of the gas produced by coking furnaces, the hydrogen sulfide level is around 100 ppm, while the organic sulfur level is about 130 ppm. I would like to ask if there are any effective desulfurization processes that can be used to further purify this gas
You can consider using the alkali absorption method or zinc oxide adsorption method for advanced purification, as both methods are effective in removing hydrogen sulfide. The alkali solution absorption method can effectively convert hydrogen sulfide into sulfates, while the zinc oxide adsorption method can remove both hydrogen sulfide and organic sulfur, thereby improving the purification efficiency of gas. Composite processes can also be considered, combining various techniques such as physical adsorption and chemical absorption to achieve a lower sulfur content. .
