The graph above has the straight line constructed from the two points x1,y1 and x2,y2, with a straight line to join them (I think with a gradient of L/G), and the curved line is made from 10 stages of the column assuming constant mass transfer eg. x1,y1  x2,y2  x3,y3 x4,y4 ... .. .x10,y10.

I just need to know if the curved line is the equilibrium line and if not how do I draw one I need an equilibrium line to work out the stages, I think.

Thankyou.

Hello moleman1985,

Yes, I believe you are correct.  I have rarely seen an equilibrium line that is truely linear.

Cheers,
