✦ Synopsis
In this paper we describe plateby-plate calculations of separation columns using finite difference equations. The calculations were performed on the WEIZAC digital computer. The purpose of the calculations was essentially twofold: (a) comparison of various ideal cascades among themselves and with constant flow cascades. (b) Preparing a series of graphs from which the behaviour of a given column with given input parameters can be predicted a priori. In addition, the results of the methods are compared with the results of calculations based on the solution of differential equations for one system for which such a solution is available. The calculations are also compared with experimental results on fractional distillation and thermal diifusion columns.
