Figure Z23

x-y diagram showing both stripping and rectifying operating lines we simply move vertically up a line through xB until the VLE curve is intersected, and then read off the yB value.

A component balance around the reboiler gives:

This is the stripping operating line [equation (2.28)] applied to the reboiler stage. We know yB. We could plug into equation (2.31) and solve analytically for Jii. Alternatively, we can solve graphically for xx simply by moving horizontally on a straight line through yB until the operating line is intersected. Then this
