A calculation method is proposed for a non-ideal multicomponent distillation column with any number of feeds and side-cut streams. The tridiagonal matrix method proposed for ideal systems by Wang and Henke was modified for non-ideal systems by means of an approach based on the principle of perturbation. The over-correction phenomenon in iterative calculations is improved by introducing a correction parameter. The applicability of the proposed method is demonstrated by the excellent convergence for several examples.
