The effect of random and systematic errors of the equilibrium distribution concentrations on the number of stages of countercurrent extraction with various consumption of solvent

Abstract

On using five hypothetical systems differing in the extent of mutual solubility of components, tie-line slope, and type of binodal curve, the effect is evaluated of random and systematic errors in the liquid-liquid equilibrium distribution concentrations on the accuracy of calculated number of theoretical stages of isothermal countercurrent extraction under different operating conditions.
