| 1: | Consider the ratio control strategy shown in Figure 12-1b. If the blend stream has a concentration measurement and controller, construct the control instrumentation diagram where the output of the concentration controller is the desired ratio of stream B to stream A flows. |
| 2: | Consider the high-temperature select control problem shown in Figure 12-2. Modify the control instrumentation diagram to include a cascade-control strategy, where the output of the reactor temperature controller is the setpoint to a reactor inlet temperature controller. The reactor inlet temperature controller then manipulates the flow to the preheat exchanger. |
| 3: | Consider a gas-phase reactor where a valve on the output stream is normally regulated to maintain ... |
