Considering the following separation problem:

Given is a feed solution of methanol and water with a molar fraction of \begin{equation} 30 \ \% \end{equation} methanol.

This is to be concentrated to a molar fraction of \begin{equation} 80 \ \% \end{equation} methanol.

Furthermore, given is:

$$\qquad$$$$p$$ =1.013 bar
 $$ x^B$$ =0.05 
 $$q^F$$ =1 
 $$ f $$ =2.5 
 $$\dot B$$ =560 mol/h

 

Calculate the values for the following parameters using the app [Link] if necessary!

  • Minimum reflux ratio $$R^L_{min}$$:
 
  • Reflux $$\dot R^L\dot D$$:
  mol/h
  • Number of theoretical separation stages $$n_{Enriching}$$:
 
  • Number of theoretical separation stages $$n_{Stripping}$$:
 
  • Separation factor (Feed) \begin{equation} \alpha_{12}^F \end{equation}
