Cоntrоl System Design fоr а Volаtile Reаctor-Gas Scrubber System A specialty chemical plant operates a continuous volatile polymerization reactor that releases a toxic gas by-product (NOx) as part of its process. The reactor is cooled using a chilled ethylene glycol jacket, and the NOx emissions are controlled by a gas scrubber system that injects caustic solution to neutralize the gas before release. Reactor Temperature ControlThe reactor’s temperature behavior with respect to coolant flow is characterized by a first-order transfer function, where its steady state gain is -3.5 (°C/ L/min) and it took 25 min to ready steady state. The temperature is measured by a Resistance Temperature Detector (RTD) with a first-order lag of 20 s and is sensitive with noise. The valve controlling coolant has a time constant of 25 s and is normally 50% open, while 50% open, it operates at 500 L/min. The transmitter outputs 0–10 V for 50–150 °C, and the controller outputs 0–10 V to the valve. you can label y(s) = T'(s) the deviation of reactor temperature from nominal (°C),u (s) = Q'(s) is the deviation of coolant flow rate (L/min) from nominal (500 L/min),NOx Scrubber Emission ControlThe scrubber has been tested and exhibits the following transfer function: where time constant is in minC'NOx(s) is the NOx concentration deviation (ppm) from nominal (200 ppm),F'NaOH (s) is the flow rate of caustic solution (L/min) from nominal (150 L/min),The sensor has a measurement gain of 2.0 mV/ppm and no delay,The actuator (a dosing pump) has a gain of ±1.5 L/min/V and exhibits a 0.2 min time constant. The controller used for the Emission Control is a PI controller with positive proportional gain, and the integral time constant is 0.6 min. Provide the block diagram(s) for both control systems (with all transfer function block clearly label except the control block for the Temperature controller, all unit of each signal needed to be labeled)Identify the following information for each control loop systemControlled Variable (CV)Manipulated Variable (MV)Likely Disturbances (DVs)
