Gas-liquid separation
Thread Content
If the relative volatilities of the two liquid phases that need to be separated through the fractionation tower are relatively large, is the mass transfer resistance of the liquid phase greater or smaller? ?
This question requires looking into physical chemistry. I don’t know the principle, but I know that for a fractionation column, the relative volatility is high, and the plate efficiency is low. From this point of view, the liquid phase mass transfer resistance should be large.
Thank you all for your answers. But if you could tell me why, I would be more grateful. :)
Big, it’s easy to understand. A large relative volatility means that the mass transfer and heat transfer effect increases, that is, the mass transfer resistance increases! !
