Abstract

Various methods of calculation of the number of independent variables (degrees of freedom) are analyzed for chemical-engineering objects, including continuous distillation columns with different organizations of external flows and auxiliary equipments. The number of degrees of freedom is demonstrated to be invariant with respect to the type of calculation for the distillation process (design, confirmatory, or designconfirmatory calculation).
