I'm currently designing a plant, converting n-butene to 2-butanol using water and catalyst.
Using Aspen to run the simulation. However, I am facing problem with azeotrope of water and 2-butanol. Since I don't know how to input azeotropic column using Aspen, so, what should I do?

I do have other side product like Di-sec-butyl ether.

How to increase the purity of my product?
