What is the composition of AdBlue?

AdBlue is the name used internationally for an additive developed for the chemical and motoring sectors. It’s an extremely high purity, 32.5% aqueous solution of urea (minimum 31.8% – maximum 33.3%) that transforms nitrogen oxides into nitrogen (N2) and water vapour (H2O) by means of chemical reduction.

Can I make my own AdBlue?

No, the vehicle will not be able to be started. It’s the same for all AdBlue vehicles; legislation prohibits it to start with no AdBlue in the tank.

What is the AdBlue ratio?

AdBlue is a colourless liquid that is made from a mixture of high-purity urea (32.5%) and deionised water (67.5%).

Is AdBlue just urea?

While AdBlue is comprised of approximately 32 percent urea, our urine includes approximately two percent urea. It’s mostly water, and the rest will depend upon one’s diet. Some other elements of urine (again, depending on your diet) could be detrimential to the AdBlue system, and could cause some expensive repairs.

What urea is in AdBlue?

32.5% urea
1. Where does urea come from? AdBlue is composed of 32.5% urea and 67.5% demineralized water. Invented in 1828, Urea is a synthetic product derived from ammonia.

How do you make AdBlue solution?

There are two ways of making AdBlue®:

1. the first involves dissolving granules of solid urea, called prills in demineralised water;
2. the second involves mixing synthetic urea with demineralised water.

How do you make homemade AdBlue?

How do you make urea for AdBlue?

Well, AdBlue urea is made by heating up synthetic ammonia and carbon dioxide. The urea is then added to the de-ionised water to create AdBlue. AdBlue sits in a separate tank to diesel and, unlike petrol or diesel, isn’t injected into the engine. Instead, it’s injected into the exhaust system.

How is AdBlue urea made?

What urea is used in AdBlue?

32.5 percent urea
However, you may well be interested to know that AdBlue is intrinsically safe, as it has a composition that’s 67.5 percent de-ionised water and 32.5 percent urea. Automotive urea, in case you were wondering, is not an animal derived product although we do excrete urea in urine, it’s at much lower concentrations.

What type of urea is used in AdBlue?

This AdBlue is sold around the world and comes from a solution of high-purity, virgin urea. Urea is produced synthetically from ammonia and CO₂ (carbon dioxide), from which Yara’s AdBlue is extracted directly as “hot melt” urea, which uses a different process from fertilizer grade urea.

What percentage should DEF be?

32.5%
The ideal, or target reading is 32.5%. If under, more DEF con- centration is needed. If over, the urea concentration is too high. In reality, most DEF purchases will consist of premixed containers.

What percentage should def fluid be?

DEF consumption can vary based on environmental factors but is normally expected to be between 2 and 3 percent of fuel consumption. This means that for a diesel truck with a 36-gallon gas tank, around 1 gallon of DEF will be used for every full tank of gas.

What’s the pH of urea?

The conductance method using four acid concentrations ex- tending from 4.56 X l0 -4 to 9.13 X 10 -4 M PNP in 9.44 M urea yielded an average pK of 6.19. The measured pH of a 0.05 M equimolar buffer of PNP and its sodium salt was 7.84. These results are entirely consistent with those obtained on the acetic acid system.

How do you make a 40 urea solution?

Preparation Instructions Aseptically add 5 mls to 95 mls of sterile molten Urea Agar Base (Christensen). Mix well and dispense in sterile tubes.

What is the best DEF fluid?

The best diesel exhaust fluid meets the Environmental Protection Agency’s standards and is free from impurities. Valvoline’s Premium Blue Diesel Exhaust Fluid is a top choice because it is compatible with all selective catalytic reduction systems and meets the EPA’s near-zero nitrogen oxide emissions levels standard.

What is good DEF concentration?

The ideal, or target reading is 32.5%. If under, more DEF con- centration is needed. If over, the urea concentration is too high.

Is urea made from urine?

Urea, also known as carbamide, is a safe, useful compound with a significant history. It is a naturally occurring molecule that is produced by protein metabolism and found abundantly in mammalian urine.

What is AdBlue®?

AdBlue® = registered trademark of the VDA (German Automotive Industry Association). BASF is an extraordinary member of the VDA (German Automotive Industry Association), which owns and licenses the AdBlue® brand. Only officially approved manufacturers can market diesel exhaust fluid (DEF) under the AdBlue® name.

Can I make AdBlue® myself?

Making AdBlue® yourself may have adverse repercussions on your vehicle. the first involves dissolving granules of solid urea, called prills in demineralised water; the second involves mixing synthetic urea with demineralised water. Did you know? The AdBlue® trademark is registered by the German Automobile Industry Association (VDA).

What type of water is used for AdBlue®?

A specific quality and high purity of water is used for AdBlue® to avoid all contamination. Using out of specification water in the production of AdBlue® is probably the greatest threat to your catalyst, and therefore your vehicle, so it is essential to purchase from a supplier who produces AdBlue® to the global ISO specification.

What is the AdBlue specification according to the iso-22241 standard?

AdBlue® specification according the ISO-22241 standard. #N#Min. Max. Units. Urea Content. 31.8. 33.2. % (m/m) Density at 20°C.
