A kutatási téma leírása:
a.) Antecedents:
Publications in international journals and conferences, project works, BSc and MSc theses and the research projects No. K-106268 (2013-2016) and K-120083 (2016-2019) funded by the Hungarian Scientific Research Funds (NKFI-OTKA).
b.) Aim of the research:
The aim of the research is to study and optimize special batch distillation methods (batch extractive distillation, batch heteroazeotropic distillation) applied to the separation of azeotropic mixtures by computational modelling. The optimization of batch processes is a dynamic optimization problem that cannot be solved by the built-in optimizers of professional flow-sheet simulators. Thus, there is a need for the development of external optimization modules that can be coupled to the flow-sheet simulator. The aim of the research work is to develop derivative-free optimization methods that are able to optimize special batch distillation methods with moderate computational effort. The applicability of the method can be extended to include multiple objective functions or off-cut recycle. The results of optimization can be validated by laboratory experiments.
c.) Tasks, main items, necessary time:
• Study of the previously collected literature (4 months)
• Review of new literature (3 months)
• Getting acquainted with the available programs and codes (2 months)
• Algorithm development and calculations (15 months)
