Problems with the separation effect of distillation and evaporation
Thread Content
If the evaporation process is controlled very slowly, can the purity of the evaporated solvent be the same as the distillation effect?
The volatility of each component during distillation is different.； Evaporation operates solutes that are non-volatile. Isn’t it easy to compare these two operations?
It can be said that it is theoretically feasible, but in practice it cannot be achieved. Just like flash evaporation, no matter how slow it is, it is only equivalent to one equilibrium stage, and it is impossible to reach multiple equilibrium stages of distillation. Does the poster say so?
Evaporation can only be distillation, which is a single-stage equilibrium.
What you said above just solved my confusion.
