Contamination is a key factor in diesel degradation
Diesel fuel is a vital source of power for many industries, but it doesn't last forever. Proper storage and maintenance are crucial to prevent diesel degradation and ensure its longevity. One of the most significant factors contributing to diesel degradation is contamination.
Contamination occurs when diesel fuel is exposed to water, particulate matter, rust, or other foreign substances. Water intrusion is particularly detrimental as it promotes microbial growth, which can lead to the fuel tank's clogging and potential generator failure. This intrusion can happen through condensation, leaks, or improper handling. Therefore, it is essential to maintain the fuel tank's cleanliness and integrity to prevent water ingress.
Additionally, the temperature plays a crucial role in diesel fuel degradation. Extreme heat can cause the lighter components of the fuel to evaporate, while extreme cold may lead to paraffin wax crystallization. To mitigate this, it is recommended to store diesel in a cool tank, ideally around 20°F, and not exceeding 85°F. Underground tanks or providing a canopy can help maintain optimal temperatures and reduce exposure to the sun and water sources.
Furthermore, the use of fuel additives can help extend the shelf life of diesel fuel. Adding antioxidants and fuel stability treatments can prevent chemical breakdown and stabilize the fuel. However, it is important to choose additives specifically designed for diesel fuel and not general fuel sources. Regular maintenance, such as cleaning the tank every ten years, is also essential to removing any built-up contaminants and preserving the fuel's quality.
By understanding the factors that contribute to contamination and implementing proactive measures, such as proper storage, temperature control, and fuel treatment, diesel fuel users can effectively delay oxidation and maintain the fuel's optimal condition for an extended period.
