Two new graphical methods are presented for the calculation of equilibrium stages (ND) for countercurrent extractors in which hackmixing is the only controlling factor for mass transfer.
Both proposed methods are based on a stagewise model with back-flow. One method is developed for the calculation of ND for one-solute distribution and the other is developed for two dependent solutes distribution. The proposed graphical solutions for the two methods are different, but both can be straight-forwardly applied to the case of equilibrium distribution.
