A dynamic simulation model for the pilot mDWC described in Section 2.1 is set up in Aspen HYSYS V11 based on the equilibrium stage model, in an attempt to adapt the simulation as closely as possible to the real column. Fig. and 2 in the supplementary material show the corresponding flow sheet along with a detailed description of the simulation setup. The considered test system is an equimolar mixture of ethanol, n-propanol, i-butanol, and n-butanol and NRTL is chosen as the underlying thermodynamic model. The NRTL-parameters can be found in a work of Preißinger . Vapor-liquid data for all six binary subsystems of the four components are checked and are in good accordance with literature data from the Dortmund
