| Summary: | A continuation method of the kind predictor-corrector is presented for completely tracking of the pinch points branches related to the products or pseudoproducts of a homogeneous azeotropic distillation column. The method easily handles the turning points allowing the localization of the tangent pinch points. The foundation of the concept is in the ideas of Fidkowski, Malone y Doherty; however, some novelties are included, as the initiation strategy for calculations, the way to obtain the tangent vector and the set of equations on which the technique is applied. Three examples are illustrated with the solutions of acetone + chloroform + benzene, acetone + chloroform + methanol and acetic acid + amyl alcohol + amyl acetate, emphasizing cases that show better separation possibilities in the finite reflux condition than with total reflux operation.
