A computer program is presented for the optimization of a two-column distillation system involving a two-component mixture. The economic reflux ratios in each column are determined using the McCabe-Thiele Method. Activity coefficients are computed by either the Wilson equation, the Margules equation, or both. The program is general and may be used for any binary system where the assumption of constant molal overflow is valid.

Options in the program permit use of either column in separate calculation schemes.

While the optimization effort was prepared in general terms, the initial work was directed toward the acetone-water system. Full data for this system are included in the program, but this specialty can be bypassed.
