Chapter 21 Regulating Process Conditions
Over the life of a plant, it is important for operating conditions to be regulated in order to obtain stable operations and to produce quality products efficiently and economically. In this chapter, we consider regulation; a subset of this is process control. Regulation establishes the strategy by which the process can be controlled. Regulation also involves the dynamic response (transient behavior) of the process to changes in operating variables. The latter will not be considered here as it is covered in the typical undergraduate process control course.
The regulation of process operations involves an understanding of two facts:
In most situations, processes are regulated, either directly or indirectly, ...
