Is there any desulfurization technology that only removes sulfur without removing carbon?
Thread Content
Hello, all the experts and skilled users! Is there anyone familiar with desulfurization services? I have a request: I want to purify hydrogen sulfide gas mixed with carbon dioxide to obtain pure hydrogen sulfide gas. Is there any way to do this? Is there any desulfurization technology that only removes sulfur without removing carbon? If anyone knows, please let me know
It doesn’t seem clear whether the product should use hydrogen sulfide or carbon dioxide.
Solvents that can remove sulfur but not carbon are not easy to find. However, the absorption capacities of methanol and NHD for hydrogen sulfide and CO2 vary significantly at different temperatures; the original poster can take advantage of this property to explore the possibility of concentration enhancement.
It should be decarbonization, not desulfurization; hydrogen sulfide is needed
Simple decarburization is not easy to carry out, right? I need hydrogen sulfide. I wonder if there is a technology that only removes sulfur but not carbon. In this way, hydrogen sulfide is absorbed, while carbon dioxide is released. The desorbed absorbent solution then yields pure hydrogen sulfide gas. I don’t know if there’s such a good solution. I really hope to get guidance from experts with experience in this area. I hope you can kindly offer your advice!
Since they are both acidic gases, it’s really tricky. :lol
Has anyone worked on MDEA desulfurization? I hope to learn from you and exchange ideas. Are there any friends in the group who are from the Dongcangyi refinery?
MDEA can also remove carbon dioxide
It is said that by adjusting the concentration of the MDEA aqueous solution and making appropriate mixtures, it is possible to achieve almost no absorption of carbon dioxide. I want to obtain pure hydrogen sulfide gas to prepare sodium hydrosulfide
