Which action should you take?

Choose only one option

Limited data visualization and control features

Use of analog signals over digital ones

Simplicity in configuration and low initial cost

Real-time data acquisition and remote control over large-scale operations

Question 3: What is the primary function of a PID controller in a chemical process control system?

Which action should you take?

Choose only one option

To monitor financial aspects of chemical operations

To measure the temperature of a specific process

To provide continuous control of a process variable by adjusting an output

To optimize the layout of the plant

Question 4: In the development of a control algorithm for a chemical reactor, how do you account for large process disturbances, such as a change in feed composition?

Which action should you take?

Choose only one option

Ignore disturbances and rely on standard PID control

Use manual adjustments instead of automated control

Use feedforward control to anticipate disturbances and adjust control actions proactively

Increase the proportional gain to compensate for disturbances

Question 5: How do you optimize control algorithms for energy efficiency in a chemical manufacturing process?

Which action should you take?

Choose only one option

Design algorithms that optimize energy consumption, adjusting operational parameters in real-time based on energy usage data and system dynamics

Implement control algorithms that ignore energy efficiency in favor of production speed

Focus solely on maximizing output

Increase the speed of the process without considering energy use

Question 6: What role does a PID (Proportional-Integral-Derivative) controller play in process automation systems?

Which action should you take?

Choose only one option

It directly measures temperature and pressure to set the desired output

It adjusts control variables based on the deviation from a setpoint, minimizing errors and improving stability

It restricts operator access to process control adjustments

It stores historical data to predict future trends in process parameters
