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.

Advantages:

they provide physical insight into process behavior.

they are applicable over a wide range of conditions.

Disadvantages:

they tend to be time consuming and expensive to develop.

theoretical models of complex processes include some model parameters that are not readily available.
