Relation between column efficiency and plate efficiency in a rectifying column is investigated by considering the liquid mixing on the plate. Under the assumption that the vapor on the plate is in equilibrium with the liquid at the center of the plate, the column efficiency is derived as a function of the plate efficiency, λ(=mV/L) and the mixing parameter F for the case where the equilibrium curve is given as a straight line. It is shown that the results can be applied by using the mean value of λ in case the equilibrium curve is not a straight line.
