Fig. 5.7. Illustration of operation of process configuration in Fig. 5.2 in a McCabe-Thiele diagram at different Damkohler numbers ating point is obtained from the intersection of the operating lines of the distillation section and of the reactive total reboiler. The latter is only a straight line for a first-order reaction (n = 1). The two operating lines are given by the corresponding mass balances

The resulting reboiler operating point has the coordinates

Fig. 5.7 shows how the reboiler operating point is shifted by changing the Damkohler number. All reboiler operating lines for the different Da numbers meet in the pole point «reb whose coordinates are given by
