Solubility of disulfides in alkaline solutions and gasoline
Thread Content
Is there a significant difference in the solubility of disulfides in alkaline solutions and gasoline? Are there units for gasoline desulfurization that recover disulfides?
The solubility of disulfides in gasoline is definitely higher than in alkaline solutions; otherwise, how could the alkali-free dewaxing process work? (I’m not sure if this is correct.) We use the alkali-free dewaxing method for gasoline refining here, so the disulfides are not recovered!
What standards are followed for the sulfur content in your gasoline?
Dithiides are highly soluble in gasoline, as the dithiides present in the alkaline solution used for desulfurization of liquefied gas in our system are removed by absorption using gasoline after the regeneration of this solution
Why not use diesel? 》Is there any difference?
Because the absorption of disulfides involves a process of mixing with alkaline solutions, diesel is prone to emulsification.
Does alkali-free deodorization of gasoline not serve to reduce the sulfur content in gasoline? If it has no effect on the total sulfur content of gasoline, then what is the purpose of alkali-free deodorization of gasoline? Looking at the deodorization process of this substance, disulfides remain in the gasoline; so how is the sulfur content in gasoline reduced? I’m a beginner; I hope you can give me some guidance: handshake
Disulfides are insoluble in water; they have a density greater than that of water but less than that of alkaline solutions. However, disulfides are soluble in gasoline, which can only be used for deodorization and cannot remove the disulfides, while liquefied gas can eliminate these disulfides
Dear seniors, how should sodium thiosulfate generated during the process be handled?
