Chapter 12. Analysis of the Degrees of Freedom in Steady-State Processes

12.1 Main Concepts

Your objectives in studying this chapter are to be able to

1. Identify the names and numbers of variables in the streams entering and leaving a processing unit, and the variables associated with the unit itself

2. Determine the number of independent equations for each processing unit, the constraints

3. Calculate the number of degrees of freedom (decision variables) for single units and combinations of units both without and with a reaction taking place

4. Specify the values of variables equal to the number of degrees of freedom for a unit

Now that you have accumulated some experience in making both material and energy balances, it is time to apply this ...
