Instead of solving a set of N nonlinear equations (as has been proposed by the author and his coworker), the problem may be solved iteratively as a linear one. The proposed method converges rapidly and the number of iterations is practically constant regardless of the number of stages in countercurrent cascade N and the degree of nonlinearity of equilibrium formula. The method proved to be suitable for computation on desk-top calculator.
