The Exothermic reaction A → 2B is taking place in the CSTR reactor shown inFig. E.6. Component A is considered as expensive material. Since the reaction isexothermic the temperature of the tank need to be controlled at 60 °C to avoidtemperature run-away. Also, the outlet concentration of C₁ is required to be atset-point CSP. The level of the CSTR product mixture is controlled to avoid theoverflow.1. What is the type of valves V-1, V-2, V-4?2. What is the type of controllers used for the control loops in the process?3. What is the action of the controller selected (reverse, direct)?4. Draw a P&ID diagram of the schematic given for each control loops.
