Reactors for Parallel-Reaction Networks

A liquid-phase reaction involving the following two parallel steps is to be carried out in an isothermal PFR. 

For both cases (a) and (b), the material balance (design) equations may be written gener-ically as 

Equations (A), (B), and (C) are not all independent but may be integrated simultaneously using the E-Z Solve software (file exl8-6.msp) to obtain concentration-volume profiles for A, B, D, and U, as well as SD/A. 

Furthermore, by definition, at any point in the system, including the outlet, 

Integration of (A), (B), and (C) gives the following results (see file exl8-6.msp)
