QUESTION (a) Figure 6 shows an exothermic reaction process where a temperature controller (TCI) is used to drive a control valve so as to keep the reactor temperature at its setpoint Tsp. Feed in TCI Reactor temperature set point (master) Sie Water surge tank LC LT Reactor Cooling water out Product Cooling water makeup Circulation pump (b) (c 70 Figure 6 Exothermic Chemical Reactor Temperature Control Assuming there is a fluctuation in the cooling-water iniet temperature and supply pressure which results in fluctuation in the jacket temperature T, it will therefore be necessary to keep a check on this temperature by installing another temperature controller such that the temperature controller (TCI) drives the setpoint of the newly installed temperature controller to keep the reactor temperature at its desired setpoint. The newly installed temperature controller, in turn, drives the control valve to match the jacket temperature with the setpoint the temperature controller (TCI) is requesting. (i) What type of control loop is described? (2 marks) (ii) Draw instrument diagram to show the implementation of the control scheme described.
