AdBlue Manufacturing Methodology

There are basically two methods used to manufacture AdBlue. First one is the “Hot-Melt”Urea production method which is recognized across the industry as producing the highest purity grade of AdBlue. The urea is in its ‘virgin’ liquid (32.5%) form when it is combined with the de-ionized water (67.5%) so there is rarely a chance of contaminants being introduced during manufacture, but its disadvantages are far away to the market where it is needed and takes longer transportation time. 

Another widespread method of manufacture is by dissolving of solid urea (32.5%) in de-ionized water (67.5%) which is easy to deliver the raw material and produce locally. However, most of AdBlue® manufacturers faced with final retail price continued to fall and squeezing its revenue generation and margins, therefore, some of producers will turn to use non-qualified industrial grade or agricultural grade urea material in order to reduce material cost. As the end result, there will be a risk of non-compliance with ISO22241 standard, making the SCR vehicle system failure events, time to time.
