Chapter 8 Example

PBR with heat exchange

The elementary reaction

is carried out in a PBR with constant coolant temperature, TC

We want to determine both the conversion and temperature profiles

Write a Polymath program to plot X and T vs. W.

Solution


 

 

 

 

 

 

Solution

Mole Balance

Rate Law

Stoichiometry

Combine

Energy Balance:

A variation of this program can be found on the CD under the Chapter 8 Living Example Problems under the name "Lecture 15/16 Variable Coolant Temperature." However, to work the above example, you will need to set the coolant rate at=100g/s.

Use this when working with the Living Example Problem.
