The present work describes an Advanced Process Control solution applied to a cement plant grate cooler. The grate cooler is located downstream of a clinker rotary kiln with the purpose of suitably cooling the clinker. Clinker is cooled through the action of multiple cold air fan units as it is transported by the clinker rotary kiln. A Model Predictive Control …

For example, to guarantee that the reaction continues at the best rate possible in a chemical plant, a PID controller may govern the flow rate of reactants into a reactor. In order to reduce error, it continually measures the process variable (flow rate) and modifies the control variable (valve position). By doing this, it guarantees that the ...
