hi,
I want to seperate Propylene carbonate from Propylene glycol (in a liquid solution)...
can someone refer me to a data source of Vapor liquid Equilibrium chart of thos two chemicals?
maybe,
but i need to calculate how high is the distillation tower, so i need number of plates at least... i have "Fenske's" equation but for that i need the average volatility of those two. didnt fint that until this point.

The best way to size the tower is a quality simulation. If you don't have that then you should get your flow rate into the column. The inlet coposition, and desired outlet compostion and either let a tower vender size the column or get an outside contractor to size the column. If the column is very big it will totally be worth the money. If it is very small you may want to go with Fenke's and wing it.
