can we use Centrifugal force and membrane to separate azeotropic mixture?

Question

dear all, I see people use centrifugal decanter to separate mixture of liquid and solid, after that, liquid is transfered to membrane to separate liquid mixture.
But I consider that Can we use both centrifugal decanter and membrane to separate azeotropic mixture of liquid such as ethanol anf water to increas capacity as well as reduce time to dehydrate this azeotropic mixture ?
It mean that we will install membrane in centrifugal decanter...
Thanks

Answer 1

An azeotrope is a special mixture of two or more solvents in such a ratio that its composition cannot be changed by simple distillation. This is because when an azeotrope is boiled, the resulting vapor has the same ratio of constituents as the original mixture of liquids. Because composition is unchanged by boiling, azeotropes are also known as constant boiling mixtures (especially in older texts). Indeed the word azeotrope comes from the Greek "zein tropos", or "constant boiling".

Therefore, at normal temperature condition there is no phase separation or distinction,hence, centrifugal force and membrane filteration can not separate azeotropic mixture.

Answer 2

azeotropic mixtures require a fractionating column for separation to occur, this is due to their very close difference in their boiling points..

you may try reading on chemical engng books, particularly on unit operations

Answer 3

Only if the densities differ sufficiently.
