TABLE 5.3 Rate Constants for aj aj Case for Van de Vnsse Kinetics 

Recall that the operation of a CSTR is different to that of a PFR. The CSTR operates at a single point for a specific feed point and residence time— specifying both 

Component D is therefore not consumed by the reactor, but rather the low value of Cd for longer residence times is the value required in the CSTR for the particular residence time specified— the concentration of D must take on a value that solves the CSTR equation. Different values of t correspond to different values of Cjj, which may be larger or smaller than previous values of Cp. The rise and fall in the value of Cp as a function of t is dependent on the CSTR solution required by mass balance. 

The concentration of B at point P is Cg = 0.052 mol/L. Although point L yields a higher concentration when only a CSTR is employed, a PFR initiated at point L does not achieve the highest concentration of B. 

Now that the AR has been determined, optimization of the system may be carried out if a suitable objective function is supplied. The Van de Vusse reaction involves the production of a number of products (B, C, and D). Since component B is assumed to be the desired product, it may be useful to understand the yield of component B achievable in the system,
