TRANSIENT OPERATION MODES AND DYNAMIC MODELING

Mathematical modeling can be applied to transient data. The crucial issue is to include the accumulation term (dn,/dt) in all mass balances and to take into account the changes

For the adsorbed surface components, the mass balance is written as 

The component generation rates are obtained from the stoichiometry 

The initial condition for the system is that the inlet concentrations are known during the experiment
