Question 1: What is the primary purpose of using a cascade control strategy in a chemical reactor?

Which action should you take?

Choose only one option

To reduce the effect of disturbances in the main control loop

To increase the speed of the system response

To simplify the control system by using fewer sensors

To eliminate the need for feedback control

Question 2: How does the integration of feedforward control enhance a PID control system in a chemical plant?

Which action should you take?

Choose only one option

By increasing the system's response time

By simplifying the control algorithm

By compensating for disturbances before they affect the controlled variable

By eliminating the need for a feedback loop

Question 3: How can system reliability be improved during the design phase of a control system in the chemical industry?

Which action should you take?

Choose only one option

By including redundant components and ensuring fail-safes are in place

By minimizing the number of control elements used in the system

By prioritizing fast response times over reliability

By focusing on aesthetic design rather than system functionality

Question 4: What type of calibration should be performed for a mass flow meter in the petrochemical industry to ensure its accuracy?

Which action should you take?

Choose only one option

Calibration using theoretical equations based on fluid dynamics

Calibration using only manufacturer-provided reference values

Calibration at various flow rates using a known reference fluid

Calibration at a single flow rate under standard conditions

Question 5: What is the primary benefit of using wireless instrumentation in control systems for chemical plants?

Which action should you take?

Choose only one option

Ensuring that control actions are executed faster

Lowering the cost of instrumentation and sensors

Reducing the complexity of the wiring system

Enabling real-time data collection and monitoring without the need for extensive wiring

Question 6: What is the significance of actuator selection in control systems design for chemical processes?

Which action should you take?

Choose only one option

Actuator selection determines the system's responsiveness and precision in maintaining process control

The cost of actuators is the most important factor in the selection process

Actuators are not crucial as long as they function without failure

Actuators should be selected based solely on energy consumption
