What is a key factor in achieving uninterrupted equipment operation?

• Increasing production speed

• Performing timely preventive maintenance

• Installing larger motors

• Reducing the number of operators

• Using cheaper spare parts

Which of the following contributes most to material efficiency?

• Replacing equipment every year

• Monitoring and adjusting process parameters

• Increasing storage space

• Reducing the number of cleaning cycles

• Hiring more operators

What could indicate an imbalance in mass flow within a process?

• Slight changes in color of the product

• A discrepancy between input and output weights

• A decrease in maintenance requests

• A change in room temperature

• A drop in staff attendance

What aspect of electricity use most affects overall efficiency?

• The type of switchgear installed

• The distance from the power supply

• The energy consumption per unit of product

• The time of day power is used

• The voltage fluctuations in the control room

Which approach improves fuel consumption management?

• Recording actual usage versus planned usage

• Increasing fuel delivery frequency

• Using heavier fuel types

• Insulating only pipe joints

• Switching to backup tanks only

What is the purpose of calculating a material balance?

• To determine fuel type

• To organize shift schedules

• To account for all input and output flows

• To calculate machine RPM

• To check filter age

A decrease in overall process yield could most likely indicate:

• Better mixing

• Improved cleaning cycles

• Higher energy conversion

• Excess cooling

What would an economic analysis of a chemical unit include?

• Ratio of costs to useful output

• Type of control panel used

• Operator skill evaluation

• Tank diameter

• Flow direction

Which of the following best describes a process with good economic efficiency?

• High energy input, high waste

• Low product quality, low cost

• Maximum operator hours

• Optimal output with minimal resource use

• Long start-up duration

Which strategy helps to improve equipment economic performance?

• Reducing unplanned downtime

• Increasing equipment load permanently

• Avoiding scheduled inspections

• Using generic spare parts

• Increasing chemical dosage
