Comp-B - This calculator calculates the number of theoretical stages of  
binary components by using Fenske, Underwood & Gilland
correlation and by Mccabe Thiele method, for ideal
Composition Feed Distillate Comp binary components.
Methanol 0.5 0.99 0.03
Water2 0.5 0.01 0.97 - Select the componeny A(low boiling) & B (High boiling) in the data sheet,
and enter the composition data and reflux ratio times in cell marked in blue.
Operating Pressure 760 mm Hg (Abs)
- The calculation was made for saturated liquid feed.
