Hi! I don't know if I'm constructing this properly.

I have a liquid-liquid extraction process with feed stream being 60wt% solute (CHCl3) with 40wt% rest being Heptane. It is to be mixed with 100wt% pure solvent Analine. Counter-current process to produce less than 5wt% CHCl3 raffinate and at least 45wt% extract. Process runs at 25degress @ 1atm.

Here is the Ternary diagram: http://imgur.com/gTqnSCp

 

A = Heptane

B = Solvent (Analine)

C = Solute (CHCl3)

 

So here is my work so far: http://imgur.com/pGCRakO

I haven't made any calculations yet, this is all just based off connecting the lines and I've gotten 3 stages, I think that's about right? I'm not sure where to go from here and not sure how to calculate the feed to solvent ratio.

Thanks!

Oh sorry, I really don't expect it but it's just I don't really have anyone else I can speak to about this. Anyway I got an Solvent flow rate of 45kg/s.

 

With a S/F ratio of 0.6 and 3 R stages.  That video actually really helped.
