Abstract

Un sistema de control perfeccionado para una columna de fraccionamiento, en la que (i) una corriente de alimentación de componentes mezclados se introduce a través de un punto intermedio entre la parte superior y el fondo de la misma; (ii) un material de colas líquido se recupera por el extremo inferior de dicha columna y, por lo menos una porción del mismo, se vaporiza parcialmente y se devuelve a la sección del rehervidor de dicha columna; y (iii) un material de cabezas se recupera por el extremo superior de dicha columna, se condensa y, por lo menos una porción del mismo se devuelve a la sección de rectificación de dicha columna, como corriente de reflujo.
