In the international standard defining DEF (ISO 22241), it is referred to as AUS 32 (aqueous urea solution 32%). DEF is also sold as AdBlue, a registered trademark of the German Association of the Automotive Industry. Several existing standards for urea for major vehicles are as follows ; 1. International Organization for Standardization ISO 22241-1:2019 Diesel engines — NOx reduction agent AUS 32...
China's economy continues to develop rapidly and the demand for oil resources continues to grow in recent years. According to statistics, China's oil consumption in 2013 was about 490 million tons, resulting in more and more significant air pollution. The severe haze in winter in some cities of China has become more and mo...
AdBlue will freeze at - 11 ℃ ,so AdBlue hose and pump are likely to freeze in cold areas . We have mentioned that the AdBlue with 32.5% concentration is the most ideal cause AdBlue working at this concentration can reduce the NOx to the greatest extent. Too high or too low concentration will reduce the reduction of NOx. However, it should be noted that the concentration of AdBlue is greatly affect...
The need to control toxic emissions from diesel combustion engines is ever-increasing. AdBlue® are being developed to manage the output of poisonous gas like nitrogen oxide(NOx) from engine exhaust systems. Selective Catalytic Reduction(SCR) is a method of controlling nitrogen oxide emissions. This process requires diesel exhaust fluid, namely AdBlue®, to be injected into the exhaust pipe ...
Reduced raw exhaust emissions are achieved in TDI engines equipped with AdBlue® through an advanced, modified fuel injection system, exhaust gas re-circulation and optimised turbocharging. The AdBlue® solution is stored separately from the fuel tank and is pumped in small quantities into the exhaust pipe ahead of the DeNOx catalyst when the engine is running. The quantity of AdBlue® in...
Urea tanks is the storage tanks for urea solution, which contain urea solutions and are mainly used in trucks and buses. The emissions have reached the national IV standard after the vehicle exhaust passes through the urea tank .Usually the tank with the working temperature range from－40 to + 85 ℃ and volume range from 10L to 80L. Material and structure: the tan...
EverBlue Chemicals prides itself on providing high quality AdBlue® to many industries. Our Marine Urea (AUS40) SCR Catalyst is currently used by many different off shore fleets in Selective Catalytic Reduction (SCR) systems. Marine Urea (AUS40), also Diesel Exhaust Fluid (DEF), is an aqueous urea solution produced with high purity urea and deionised water. This catalyst is used in the SC...
From 2013, trucks and diesel engine cars have been created to allow users to refill their own DEF tanks. As a result, a number of truck stops and gas stations have begun offering a DEF pump next to the diesel fuel pump. You may even purchase small quantities—or order large containers for commercial use—to keep at home. Although safe to handle and non-toxic, AdBlue® can eat through some metals....
AdBlue® is non-flammable and non-explosive. It is classified as a transportable fluid with minimal risk. If you ever spill AdBlue® on your hands, simply wash them thoroughly with water. Gloves can be worn if you have sensitive skin to avoid any risk of irritation. However, you should wear protective clothing if you are handling large quantities of AdBlue® with the risk of a spill. Do n...
