Crude benzene hydrogenation extractant
Thread Content
Dear experts, I’m reaching out for help again. What should be the acceptable range for the water content in the lean and rich solutions of sulfolane, which is used as a hydrogenation extractant for crude benzene? Why
It’s not necessarily the case; for example, it could be between 0.012 and 0.018
Is the water content that low? There’s no need to necessarily provide an interpretation
Benzene and water form an azeotrope; during the distillation of aromatic products from the extract rich in aromatics, most of the water vaporizes along with the benzene, so the residual water content in the extract poor in aromatics is very low.
It’s probably to avoid the formation of an azeotrope~:)
