BATCHD - Dimensionless Kinetics in a Batch Reactor

An nth-order homogeneous liquid phase reaction is carried out in a batch tank reactor. 

The model is written in both dimensional and dimensionless forms. This example provides experience in the use of dimensionless equations. 

The batch balance for the reactant A with nth-order kinetics is 

Defined in this way, there is no governing dimensionless parameter. 

For a first-order reaction n=l, and the dimensionless time is given by k t. Make a series of runs with different initial concentrations and compare the results, plotting the variables in both dimensional and dimensionless terms. 

5 Simulation Tools and Examples of Chemical Engineering Processes 

For n=2 the dimensionless time is [k t Caq]- Make the runs and study the results as in Exercise 1. Verify that a change in k and a change in Cao have the same influence as long as the product term k Cao is maintained constant.
