Chemical Process a) Classify the control valves V1 to V7 based on their potential to regulate a particular manipulated variable to control reactor feed temperature (T4) into "strong”, “weak”, and “has no effect”, and justify your answer. b) Determine the best feedback controller among P, PI and PID controllers to control T4 via v2 and justify your answer. c) Determine the best control valve among v5 and v6 to control the separation flash inlet flowrate (F4) and justify you answer. d) Determine the best feedback controller among P, PI and PID controllers to control F4 and justify your answer given the carefully chosen control valve in part (c). e) Specify two possible disturbance variables for T4.
