Hydrogen sulfide desorption
Thread Content
I have a rather basic question – please don’t laugh at it. In the low-temperature methanol washing process, hydrogen sulfide has a higher solubility in methanol solutions than carbon dioxide, but it is more difficult to dissolve from those solutions compared to carbon dioxide. How should we understand the relationship between solubility and dissolution?
The higher the solubility, the more difficult it is to separate it. How can it be said that its separation is even more difficult than that of carbon dioxide? Hydrogen sulfide is generally removed through methods such as acidic vapor stripping, amine absorption, and alkaline absorption; it is still not clear which separation method can effectively remove hydrogen sulfide.
Difficult absorption is like active molecules: it’s hard to absorb them, but they move quickly once analyzed. Haha
