The third and the last solution to be discussed here in order to overcome the azeotrope problem is:
3) Addition of entrainer: Almost similar to the second method where we add a third component. In this case we also add another component with certain properties. The difference is that the third method adds a so-called entrainer which forms a low-boiling heterogeneous azeotrope with one of our key component. This will then lead to the formation of two phases. These two phases can be separated easily with the help of decanter for example.
Another method which might be possible to break an azeotrope is using membrane. The problem with this method is that membrane is really expensive. So to use a really big membrane (which also means big area) is really not practicable and not a smart move. Depending on the situation these are normally the choices that we have. After considering all of those concerned aspects the best one will be picked or chosen.
