Fuel and Tank Cleaning Fact vs. Fiction

Reality Check Fuel contamination and dirty tanks are a reality for tank owners today. Poor fuel quality is responsible for rising costs for tank and fuel system owners. Liability issues caused by microbial influenced corrosion abound. The tank owner is faced with skyrocketing maintenance costs and liabilities that were not a problem a decade ago.…

What’s in My Fuel? (Part 3)

The Effects of Dirty Fuel As fuel ages, it degrades. Contaminants accelerate fuel degradation. Water is the most damaging contaminant and is attributed to a host of chain reactions. When water is present, microbes can grow. They commonly find their home in emulsified and free water. Microbes do not colonize easily in dissolved water. However, dissolved…

Bad Fuel = Corrosion

One of the constants in the petroleum equipment industry is corrosion. THe problem continues to cost the industry billions of dollars each year. When I talk with tank owners, they think that corrosion is a result of moisture.  Although that is a contributing factor, the real culprit is microbial contamination. All fuel has some level of contamination. …

Ethanol Blended Fuels

Problems and Solutions Background In 2006 the EPA Renewable Fuel Standard (RFS) mandated the use of ethanol blended fuels. Since that time, conventional gasoline has been blended with 10% ethanol (E10). This is known as the “blend wall” – the capped limit of ethanol content for gasoline. (Renewable Fuel Standard (United States), 2018) It is…

Microbial Influenced Corrosion

Microbes are living cells. There are two broad categories – aerobic and anaerobic. The majority of microbes affecting fuel are aerobic. That means they need oxygen to survive and multiply. Today’s highly oxygenated fuels supply the need. The process of removing sulfur actually adds oxygen to the fuel. Water contains oxygen, is necessary for microbial…
