Chemicals on Board Ship

What is the purpose of using fuel additives on board ships?

• To attract marine life to the ship

• To improve fuel efficiency, reduce emissions, prevent corrosion, and enhance engine performance.

• To increase the weight of the ship

• To decrease the speed of the ship

Name one common type of fuel additive used in marine engines.

• Booster

• Catalyst

• Stabilizer

• Enhancer

How do fuel additives help in reducing emissions from ship engines?

• Fuel additives cause a higher release of harmful pollutants from ship engines.

• Fuel additives increase emissions by clogging engine components.

• Fuel additives improve combustion efficiency, reduce fuel consumption, and minimize the formation of harmful pollutants.

• Fuel additives have no impact on emissions from ship engines.

Explain the role of lubricity additives in marine fuels.

• Lubricity additives in marine fuels reduce friction between moving parts in engines, ensuring smooth operation and enhancing fuel efficiency.

• Lubricity additives in marine fuels are used to enhance the color of the fuel.

• Lubricity additives in marine fuels increase engine emissions by reducing friction.

• Lubricity additives in marine fuels have no impact on engine performance.

What are the benefits of using cetane improvers in ship fuel?

• Decreased fuel efficiency, reduced emissions, poor engine performance

• Improved ignition quality, better engine performance, reduced emissions, increased fuel efficiency

Discuss the importance of corrosion inhibitors in marine fuel additives.

• Corrosion inhibitors can accelerate the corrosion process

• Marine fuel additives do not require corrosion inhibitors

• Corrosion inhibitors in marine fuel additives are essential for protecting metal components in the fuel system from corrosion in harsh marine environments.

• Corrosion inhibitors are not effective in marine environments

How do deposit control additives contribute to the efficiency of ship engines?

• By preventing deposit build-up on engine components, ensuring clean surfaces, and reducing friction.

• By increasing friction

• By causing surfaces to become dirty

• By increasing deposit build-up on engine components

What is the function of stability additives in marine fuels?

• Increase fuel efficiency

• Reduce emissions

• Prevent formation of sediments and improve fuel stability.

• Enhance engine performance

Why are cold flow improvers essential in ship fuel during winter?

• To add color to the fuel for aesthetic purposes

• To reduce the risk of engine overheating

• To increase fuel efficiency in warmer climates

• To prevent the formation of wax crystals that can clog fuel lines and filters in cold temperatures.

Explain the impact of using fuel stabilizers on the storage of ship fuel.

• Using fuel stabilizers has no impact on the quality of stored ship fuel.

• Fuel stabilizers can lead to increased fuel contamination during storage.

• Fuel stabilizers can cause fuel degradation when stored for long periods.

• Using fuel stabilizers can positively impact the storage of ship fuel by preserving its quality and preventing degradation.
