Abstract

This paper completes our work on calculation of a chemical-technological complex for coprocessing cracking and pyrolysis gases on the basis of a method developed for optimal design of a chemical-technological complex (CTC) with progressive fulfilment of steps aimed at optimizing the entire complex with consideration of the mutual influence of all its processes. Using the mathematical model of the entire CTC with complete kinetic models of all the selected processes as a basis, its optimization was performed and the optimal regimes with a maximum production capacity for all the target products were selected for these processes. Advisable routes of the motion of byproducts were selected. The resulting closed flowsheet of the chemical-technological complex with notations of all inlet and outlet flows and established couplings of material and recycled flows between all the reactor elements was presented. Using the complete mathematical model and the selected economic criterion and optimization method as a basis, the chemical-technological complex was subjected to global optimization and, as a consequence, the optimally consistent material flows of the entire complex were determined with the resulting maximization of its rate-of-return, i.e., an appreciable increase in the economic efficiency of CTC operation.
