Unformatted text preview: is drawn to intersect the point {0.01,0.01} and the point where the qline intersects the rectifying section operating line. In the McCabeThiele graphs below, the first for the high molefraction region, it is seen that the specified reflux ratio is, fortunately, above the minimum value for the specified distillate mole fraction. From the plots, it is seen that 20 theoretical stages plus a partial reboiler are needed. The optimal feed stage is number 17 down from the top.

Subject: condenser.
Partial separation of a benzenetoluene mixture with a partial reboiler and a partial Given: Saturated liquid feed of 69.4 mol% benzene (B) in toluene (T) fed to a partial reboiler. Vapor from the reboiler passes to a partial condenser. Vapor from the partial condenser passes to a total condenser. Reflux from the partial condenser is sent to the partial reboiler. Distillate is to contain 90 mol% benzene (yD = 0.9) at a rate of 25 moles per 100...
