Problem 1-10 points Add the following instrumentation to the process flow diagram shown below. Use ISA notation and show all instruments using unique tag numbers. Use pneumatic control valves. All transmitters should be electronic. Assume we are using a DCS with LCD operator consoles. Required instrumentation: a) Local temperature indicators on the inlet and outlet streams to the furnace and the outlet of the reactor. Local pressure indicators on the inlet and outlet of the pump and the inlet of the reactor. A feedback control loop to control the temperature of the outlet stream from the b) c) d) e) furnace. Identify the CV-MV pairing. A back-pressure control loop on the reactor outlet stream. Identify the CV-MV pairing. All of the required instrumentation to monitor the furnace stack temperature on the operator's console in the control room including a separate high temperature panel alarm.
