Chapter 18: Models for Nonideal Reactors

Additional Homework Problems

CDP18-GC

The following data were obtained from a step tracer input to a reactor:

  1. Develop a model that is consistent with the experimental data.

  2. Evaluate all the model parameters (Vr1 = 0.26Vtot, Fr1 = 0.37Ftot)

For the second order reaction

2A B + C

with kCA0 = 0.1 min-1, a reactor volume of 1 m3, and a volumetric flow rate of 0.06 m3/min, determine the conversion of A:

  1. Using the model developed in part (a). (Ans: X = 0.62)

  2. Using the segregation model.

  3. Using the maximum mixedness model.

  4. Using the dispersion model.

  5. Using the tanks-in-series model

  6. Using both an ideal PFR and ideal CSTR
