This program is used to explain how PCA works and the idea behind the method. This example is given in the ISA book (Chapter 8, simple example) The process is composed of a valve a thermometer and a fermenter. The valve is used to control the flow rate of cooling water. The thermometer is used to measure the temperature of the fermenter.
