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} } @inproceedings{LoeweWoznyLietal.1999, author = {L{\"o}we, Katharina and Wozny, G{\"u}nter and Li, Pu and Arellano Garcia, H.}, title = {Integration of Simulated Annealing to SPEEDUP for Dynamic Optimization of Chemical Processes}, series = {AIChE Spring National Meeting, 14-18.3.1999, Houston, Paper 23d}, booktitle = {AIChE Spring National Meeting, 14-18.3.1999, Houston, Paper 23d}, year = {1999}, language = {en} } @article{LiFlenderLoeweetal.1998, author = {Li, Pu and Flender, Matthias and L{\"o}we, Katharina and Wozny, G{\"u}nter and Fieg, Georg}, title = {Dynamische Optimierung thermischer Trennverfahren in der Fettchemie}, series = {Fett : Zeitschrift f{\"u}r Wissenschaft und Technologie der Fette, {\"O}le und Wachse = Lipid}, volume = {100}, journal = {Fett : Zeitschrift f{\"u}r Wissenschaft und Technologie der Fette, {\"O}le und Wachse = Lipid}, number = {12}, issn = {0931-5985 (print)}, pages = {528 -- 534}, year = {1998}, abstract = {Die dynamische Optimierung spielt eine wichtige Rolle f{\"u}r die wirtschaftliche Prozeßf{\"u}hrung von thermischen Trennverfahren in der fettchemischen Industrie.
