Process Control Midterm exam 3/9/2022 Problem 1 (30 points) Consider the evaporator and control system shown below where the component x is separated from the mixture. We want the mole fraction Xo in the top (vapor) to be higher than the mole fraction X8 in the bottom (liquid). For each of the control valves, identify: a) in which variable's control it is used for and what variable is adjusted (manipulated) through it. b) if it should be air-to-open (AO) or air-to-close (AC). Explain why. c) should each controller be direct-acting or reverse-acting? (The VP refers to "current to pressure" transducer and it converts analog (electric) output om a controller to pressure value in order to control the pneumatic valves in the evaporator. bat is, it does not provide information on what the valve controls.)
