Se presenta un método de continuación del tipo predictor-corrector para trazar completamente los ramales de puntos de pinch asociados con los productos o seudoproductos de una columna de destilación azeotrópica homogénea. El método trata fácilmente con los puntos de retorno permitiendo la localización de los puntos pinch del tipo tangente. El concepto se fundamenta en las ideas de Fidkowski, Malone y Doherty, pero incluye algunas novedades, como la estrategia de iniciación de los cálculos, la forma de obtener el vector tangente y el grupo de ecuaciones sobre el cual se aplica la técnica. Se ilustran tres ejemplos con las soluciones de acetona + cloroformo + benceno, acetona + cloroformo + metanol y ácido acético + amilalcohol + amilacetato, enfatizando en casos que muestran mejores posibilidades de separación en la condición de reflujo finito que en la operación con reflujo total.
Abstract: 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 + chloro - form + 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.
