Abstract: A new method is proposed for waste minimization of reactor network system according to the basic principles of attainable region method used in reactor network synthesis. By this method it is meant that, the targeting of the waste minimization is divided into selectivity, relative selectivity and instant selectivity maximization. Based on those different objective functions, the optimization calculation is carried out directly in the convex region formed by arbitrary reaction and mixing, then CSTR equation and DSR equation in two and three-dimensional concentration spaces are thus attained. In the view of geometry, the CSTR locus and DSR trajectory are the smooth connection curves of reaction and mixing process; while by physical concept, every state point in the CSTR locus and DSR trajectory are the extreme value point of selectivity and instant selectivity respectively. On the basis of these studies, its suggested that a state point in reactor system has maximum selectivity if it satisfies both CSTR and DSR equation simultaneously, and that changing along the CSTR locus or DSR trajectory, the reaction path and the production distribution can be improved.
