What You Need to Know About Urea Tanks

Since 2010, most new diesel buses, trucks, cars, and sport utility vehicles come equipped with a urea tank. Urea is injected into the exhaust stream in order to remove dangerous pollutants from the exhaust and ensures that these vehicles meet the much stricter EPA regulations introduced in that year. Learn more about urea tanks in this week’s blog.

What You Need to Know About Urea Tanks

What is urea? Why did it become standard in diesel vehicles?

In 2010, the EPA released new emission standards for diesel vehicles. In order to reduce the amount of nitrogen oxide (NOx) emissions, vehicle manufacturer’s are now required to install a standard urea tank into most diesel vehicles. Producers synthesize natural gas into ammonia and CO2. When those elements are re-coupled, it forms urea. For vehicles with a Selective Catalyst Reduction (SCR) emission system, an injection of urea, comprised of 32.5% urea and 67.5% purified water, into the vehicle’s exhaust stream causes a chemical reaction that greatly reduces a number of harmful pollutants that are released into the air. The heat emitted by the exhaust causes the urea to break back down into its component parts of carbon dioxide and ammonia Exhaust gases are filtered through a catalytic converter that also contains NOx, which acts as a converter when it reacts with the urea’s ammonia and changes it into nitrogen and water, creating an environmentally innocuous substance. This greatly reduces the amount of harmful pollution that enters our airways which lead to asthma, heart disease, and respiratory problems.

Urea has become increasingly popular not only because of EPA regulations but also because it has proven to substantially increase efficiency when compared to exhaust gas recirculation (EGR) systems. Research has shown that vehicles equipped with SCR systems offer fuel savings of between 5-9% over their EGR counterparts.

What are urea tanks?

If you are storing large amounts of urea for your vehicle fleet’s needs, it must be properly stored in the right type of tank to prevent degradation as well as to ensure that the tank in which it is stored does not corrode. Xerxes fiberglass tanks make ideal storage tanks for your fleet’s urea needs as their fiberglass construction is not at risk of rusting or corroding and will protect the materials stored within from breaking down and becoming ineffective.
