This study deals with the performance of a randomly packed distillation column depending on the effective vapor–liquid interfacial area (<I>a</I><SUB>e</SUB>) and the flood ratio (<I>Fl</I>). Optimum conditions have been interpreted analytically using the proposed <I>a</I><SUB>e</SUB> model for random packings and the flood ratio (<I>Fl</I>) from the Eckert model. Capacity and efficiency data obtained for a Raschig-type ceramic ring are used to establish the basis to the model reliability in terms of a statistical log-ratio objective function. An example of scaling-up of a pilot plant with respect to the resulting statistical factors is elucidated. Some aspects of selection of an appropriate packed column design algorithm are discussed.
