Disturbances to the Column
Disturbances to the ColumnIt is obvious that the main function of a control system is the disturbance rejection, and it is also true that the impact of different disturbances is often underestimated in control design and analysis. The impact of different disturbances should be evaluated because the performance of a control scheme is different, depending on the type of disturbance it has to reject. In distillation control, in addition to the disturbances associated with the heating- and cooling-medium temperature, those disturbances associated with the feed temperature, flow rate and composition, deserve attention, particularly in multicomponent mixtures separation. Even with the reasonable simplification of feed composition lumped into the four key components—LLK, LK, HK, and HHK—the relativ…
