info_outlineIn this episode of the Fuel Pulse Show, host Erik Bjornstad delves into the basics of long-term diesel fuel storage. He explains that diesel fuel begins to degrade almost immediately after refining due to unstable molecules and environmental factors like heat, oxygen, water, and microbial contamination.
Bjornstad discusses various tests to assess fuel health, including water and sediment, oxidative stability, and microbial testing. He recommends removing water and biomass, eliminating microbial contamination, and using fuel stabilizers to slow degradation.
The episode emphasizes the importance of early intervention and regular maintenance to extend the life of stored diesel fuel, providing valuable insights for fuel storage management.
What You'll Learn:
- The chemical processes that occur in stored diesel fuel
- Factors that accelerate fuel degradation during storage
- How to assess the health and stability of stored fuel
- Key tests for evaluating fuel condition, including water and sediment, oxidative stability, and microbial tests
- Methods to slow down fuel degradation and extend storage life
- The importance of removing water and biomass from stored fuel
- Why addressing microbial contamination is crucial for fuel stability
- The role of fuel stabilizers in preserving fuel quality
- Best practices for maintaining stored diesel fuel over long periods
- The significance of early intervention in fuel storage management
Ideas Worth Sharing:
Here are three notable quotes from the podcast episode:
- "Heat speeds up all of those chemical reactions linked to degrading the fuel. This kind of process always happens faster in hot weather than cold weather."
- "Using a fuel stabilizer is an essential step to stopping the oxidative and other chemical reactions that, if left unchecked, will result in stored fuel degradation."
- "Even if you could avoid every single one of these, you would still have reactive precursor molecules already in the fuel that would start to attack healthy fuel molecules virtually from day one."
