When he's finding (L/V) min, he finds the intersection of the bottom of his absorber (0,10), with the pinch point of the equilibrium line. The connecting point on the equilibrium line, the pinch point when the number of stages goes to infinite, is found by using the equilibrium relationship y =140.8x. x = y/140.8. specifically 200ppm/140.8 = 1.42, so the top of bottom of the absorber (top of the equilibrium line) point is (1.42, 200) and the top of the absorber( bottom of the equilibrium line) is (0,10), connect those points, perform slope formula for minimum (L/V) and then multiply by 1.4 to find an appropriate (L/V) vaule.
You are correct that the final xn value should be 1.01 and not 1.06 (did neglect to subtract y1 from yn+1). The stages are about 7-8. Thanks for the correction.
I am confused. Why does the DOF contribution from the gas feed equal "C+ 2" variables? If T, P, yn+1, and V are defined.... how does that translate to a quantity of C + 2 variables? Is it because the pressure was already accounted for in the "stages" section of the DOF calculations?

You're awesome. Ialways can clarify my doubts. Congratulations for the excellent work. thanks a lot
I am confused about the formula u used for DOF, isnt it F=C-P+2 ?
The Xn value at the end of the video I believe is incorrect. You forgot to subtract by y1/(L/V) which would give you 1.01 ppm. Which gave me 7 stages.

Destro ya Xn can be calculated from the angle of the relation of the linear operation:(L/V)op=187.3=(200-10)/Xn, so, Xn=1.014
Lol almost at the end, love use of "prolly". One of my favorite slang terms
It is such an interesting and easily understandable video lecture that i like it .

I still am not getting the correct xN from stepping off stages. What does Destro ya's fix change?
Can you link one for a stripper
Isn't this stripping? The pure water is stripping the solute (chloroform) from the gas (air stream), right?
no, stripping is when the solute (chloroform) is being stripped from the solvent (absorbent) after it has been absorbed (in this case from water)
Thank you sir! It's really good!
