    ABSTRACT: The modelling and simulation of distillation columns is mainly applied to plate columns and less to random packing columns. In order to increase the mass transfer efficiency, and simultaneously to decrease the pressure drop, structured packings are being more and more used, although full models that include all the problems associated with these packing can not be found in the literature. A complete model for a distillation column using the Sulzer CY structured packing was developed. This packing, according to the manufacturer, allies the advantage of a low HETP (Height Equivalent to Theoretical Plate) with a low pressure drop, making it very adequate for units operations that need a high number of transfer units. The model developed consists of a system of partial differential equations, whose resolution can be based on the orthogonal collocation method which converts the initial system into system of ordinary differential equation, which in turn can be solved by a third order semi-implicit Runge-Kutt
