Question: Consider the process shown in Fig. Mud is brought into a storage tank, T-77, from which it is pumped to two filters. The level in the tank is controlled by LIC-1 by manipulating the exit flow. This flow must be split between the two filters in the following known ratio
R = Flow to filter 1/total flow
The two flow transmitters and control valves shown in the figure cannot be moved from their present locations, and no other transmitters or valves can be added. Design a control system that provides the desired exit flow by the level controller, while maintaining the desired flow split between the two filters.
R = Flow to filter 1/total flow
