Azeotrope separation
Thread Content
To separate an azeotrope, separation is carried out based on the composition of each component at different pressures. But is it possible to separate them by changing the composition of those components? ? Looking forward to discussion! ! !
Reply to 1# pennycrystal: The idea is good, but it’s not feasible, at least that’s what I think. Because, you see, increasing the concentration of one component may prevent an azeotrope from forming at that moment, but over time the component with the higher concentration will gradually separate, and eventually the two components will return to their original proportions, leading to the formation of an azeotrope again. In that case, wouldn’t all our efforts be in vain?
Double-column reactive distillation can be used to separate azeotropes whose azeotic composition is sensitive to pressure.
Using extractive distillation should be the best approach
Some azeotropes can be separated by crystallization.
