A kutatási téma leírása:
a.) Antecedents:
- PhD theses under French-Hungarian joint supervision (1998 (INSA Lyon), 2012 and 2013 (INP Toulouse)), Hungarian PhD theses (2005, 2009).
- Industrial applications (Sanofi-Chinoin, Gedeon Richter, Servier-Egis, Palota Environ-mental Ltd.).
- Research projects funded by the Hungarian Scientific Research Funds (OTKA): 6 pro-jects between 1995 and 2013, one ongoing (K-120083, 2016-2019).
b.) Aim of the research:
The aim of the research is to study and optimize complex distillation configurations by rigorous modelling. These configurations include facilities for reducing the energy consumption of distillation columns, such as the heat-integrated distillation column (HIDiC), dividing wall column (DWC). Additionally, the separation of azeotropic or low relative volatility mixtures using extractive distillation is also studied. The extractive distillation process requires at least two interconnected distillation columns, and significant energy savings can be reached by optimizing the process. Extractive distillation can also be realized in novel configuration, such as the DWC, and also in batch. During the research work, the PhD student performs feasibility analyses and calculations by flow-sheet simulator and develops programs for the optimization.
