It is intended to use a single column to enrich ethanol to 80% by mole, and the molar concentration of ethanol at the backside must be less than 1.0%. Determine the number of trays required for the separation. Where $ f_2 $ is the fraction of the column cross-section area or internet space that's out there for vapour flow by way of the tray. The worth of $ f_2 $ is usually zero.85~0.ninety five, that means that $ (1-f_2) $ is the fraction of the column area that's needed for downcomers.
