Dynamic Models are also referred as unsteady state models.
These models can be used for;
Improve understanding of the process
Train plant operating personnel
Develop a control strategy for a new process
Optimize process operating conditions.
Theoretical Models are developed using the principles of chemistry, physics and biology.
they provide physical insight into process behavior.
they are applicable over a wide range of conditions.
they tend to be time consuming and expensive to develop.
theoretical models of complex processes include some model parameters that are not readily available.
