Vehicle emissions are one of the key causes of air pollution and the greenhouse effect. Brenntag’s AdBlue®/Diesel Exhaust Fluid (DEF) product helps to reduce diesel engines’ harmful nitrogen oxide and soot particle emissions. Brenntag distributes this product under different names on different continents: AdBlue® in much of Europe and now also in Asia Pacific, DEF in North America.
AdBlue®/DEF is a high-purity chemical which consists of urea and demineralized water. Brenntag delivers the mixture to its customers in quantities matching their individual requirements. Each batch includes a quality certificate guaranteeing the purity of the product.
For diesel engines fitted with selective catalytic reduction (SCR) technology, a precisely dosed quantity of this urea solution is sprayed into the exhaust flow. This results in a chemical reaction which produces ammonia. Once this passes the catalytic converter together with the nitrogen oxide, the latter is converted into water and nitrogen in the form of harmless molecules which are also present in the air we breathe.
Demand for AdBlue®/DEF has increased due to the mandatory introduction in many countries of SCR technology in the diesel engines of commercial vehicles as well as other statutory regulations requiring lower emissions. Brenntag is one of the leading providers of this sustainable product as well as related services (storage, filling and transportation) and thus helps to reduce the level of air pollution associated with heavy vehicle traffic.
