AdBlue® – The Facts

What’s AdBlue®?

AdBlue® is the registered trademark for AUS32 (diesel exhaust fluid). It’s a colourless, non-toxic liquid composed of de-ionised water and urea.

FACT: AdBlue® isn’t blue at all!

FACT: Many people believe that the urea in AdBlue® is made of pig urine. It isn’t! The urea used to make AdBlue® is a man-made solution. Pig urine wouldn’t be sterile or pure enough for a commercial product!

How Does AdBlue® Work?

Small amounts of AdBlue® are injected into exhaust gases. Inside the engine’s SCR (Selective Catalytic Reduction) system, nitrogen oxide from the exhaust reacts with the ammonia in the AdBlue® and changes into harmless nitrogen and water.

Why Use AdBlue®?

It’s all about our environment! With our planet being a priority, diesel users are working hard to cut down the concentration of mono-nitrogen oxides pumped into the atmosphere by their vehicle’s exhausts.

What’s Needed for AdBlue® Storage?

AdBlue® is classed as non-hazardous, but can be corrosive so it should still be stored in bunded containers in accordance with the current environmental regulations. It’s important for its efficiency to maintain a pure solution – that means that your AdBlue® must be stored and dispensed correctly.

  1. AdBlue® needs to be stored in bunded tanks to eliminate spills
  2. AdBlue® tanks need to be compliant with the relevant manufacturing standards. Tanks should be specifically designed for storing the liquid. Not only does this protect against accidents and contamination, it’s future-proofing your storage solutions as legislation concerning pollution continues to tighten. AdBlue® is a pollutant to surface and ground water. There have been a number of serious incidents due to spillage since it was introduced to the market in 2009. Spills may be caused by faulty or inadequate tanks, corrosion of pipework or misuse of filling equipment. The Environment Agency may prosecute for such spillage incidents under Anti-Pollution Works Regulations.
  3. Tanks also need to be built to protect against extremes of temperature. High temperatures may cause evaporation and the liquid may freeze in below 0 conditions.
  4. Consider tank accessories that enable monitoring of AdBlue® levels, digital flow meters, pumps, automatic nozzles and overfill alarms. All designed for efficient use and to prevent costly contamination.

Choosing the Right AdBlue® Tank

Atlantis Tanks supply StoraFuel AdBlue® tanks in a variety of capacities. To work out the best size of tank for your needs, work out your diesel consumption. AdBlue® is generally added to fuel as 5% of the total liquid. Therefore, if your fleet uses 1000 litres of diesel, you’ll need 50 litres of AdBlue®.

AdBlue® shouldn’t be stored for unnecessarily long periods of time to minimise the risk of contamination, so it’s important to choose a tank that suits your fuel consumption.
