Higher Side-Stream Flowrate

in the last section, the base-case operating condition that optimizes TAC is not able to handle properly the impmity disturbance changes in the +20% range, the side-stream flowrate is set to be higher than the optimum case of 50 kg/h in order to handle these disturbances better in the feed F3. A side-stream flowrate of 60 kg/h is used here for illustration purposes. Notice that when the side-stream flowrate increases from 50 kg/h to 60 kg/h, the TAC only increases by 0.66% (see Fig. 9.33).
