The startup of chemical processes, such as distillation, represents one of the most complicated procedures in industrial practice. The computational and experimental results show that the optimal control policies can improve the operation performance with time saving of up to 45 \%. This allows a significant reduction of energy and raw material consumption also and consequently can lead to a more economical process.}, language = {en} } @article{LoeweWoznyArellanoGarcia2000, author = {L{\"o}we, Katharina and Wozny, G{\"u}nter and Arellano-Garcia, Harvey}, title = {Integration of simulated annealing to a simulation tool for dynamic optimization of chemical processes}, series = {Chemical engineering and processing 39 (2000) 4}, journal = {Chemical engineering and processing 39 (2000) 4}, issn = {0255-2701 (print)}, pages = {357 -- 363}, year = {2000}, abstract = {Dynamic optimization of processes in chemical industry became important in the last decade. Simulated annealing belongs to these optimization procedures, which allow to reach the global optimum, but are very time-consuming. In this paper, the simulated annealing algorithm has been formulated in a way to enable direct call of process simulators coded in the commercial simulation tool SPEEDUP. We apply simulated annealing for the determination of operation policies in a binary distillation. The developed approach allows the prediction of reflux flow rate and reboiler duty in order to minimize the operation time for product switchover of the column.
