Data to draw the binodal stability curve is given. The feed(x_F ,F) and solvent(x_S ,S)flow rate and composition are also given. How can I calculate raffinate(x_R) and extract(x_E) phase composition?

hi ,

Consider this resource

 

other videos are available on youtube.

 

 

 

 

note : You should start with mass balances ( global  and species )

 

Good luck

In my problem, I have four variables and three equations, that's where my problem lies.

 

Variables: R, E, x_R , x_E

 

Equations: 1. x_F = x_R*R +  x_E*E (Solute Balance)

                  2. S = (1-x_E)*E (Solvent Balance)

                  3. (1-x_F)*F = (1-x_R)*R (Carrier Balance)

 

And actually, raffinate and extract both with have all three of them because both the point has to lie on the given binodal curve. Basically, I have to draw a tie line but I cannot get the required points of Raffinate and Extract.

Hi ,

 

I previously stated that you should consider youtube to support your work . Key words liquid liquid extraction .

 

additional ressource is attached .

 

Good luck
