The project team will develop an analysis framework for screening candidate processes for dynamic intensification. The expectation is to express the suitability of a process in terms of one (or a few) dimensionless numbers, such that the values of the dimensionless numbers correspond to different economically optimal regimes (e.g., if the dimensionless number of a process is larger than a threshold value, periodic operation is economically more advantageous than operating at steady state). The team will begin with defining a prototype intensified system, whose model will incorporate two or more rate-based phenomena. On this basis, the team will utilize the Pi-criterion or other dynamic analysis tools to determine the operating envelopes (e.g., in terms of transport rates, transfer rates) that favor periodic process intensification.
The conceptual results will then be extended and applied to the dynamic model of a dividing wall distillation column (DWC), with the expected outcome being the identification of feasible periodic operation patterns that minimize total energy use in the column reboiler and condenser.
