To determine which of the strategies are suitable for the mDWC, a combination of simulative and experimental studies is used that include three different operating points. Initially, the discontinuous and continuous start-up strategies, that will be introduced in more detail later in this section, are investigated in a simulation study described in Section 2.3.1. The simulation study is based on the operating point P1 (Table ) which results from a previously performed optimization, that is part of another work . Based on the results in Section 3.1.1, only the continuous strategy is found to be feasible for the pilot column. Therefore, in the second part of the study, the continuous strategy is modified to reduce the start-up time.
