Industrial Products / AdBlue / ADP AdBlue
The most recent Community requirement for reducing particle matter (PM) and nitrogen oxide (NOx) emissions by diesel engines has led the main manufacturers of these vehicles to develop new engines that meet the current standards.
In 2005 the Euro 4 standard came into force in Europe for all vehicles that weigh over 3.5 tonnes (trucks, buses, etc.), obliging them to considerably reduce their emissions in comparison to the Euro 3 standard. This standard was later updated until it reached the current Euro 6, which all vehicles - including light, heavy, agricultural and industrial - have to comply with.
To achieve the required PM and NOx levels, the main vehicle manufacturers and their suppliers developed and adopted SCR Technology - AdBlue (Selective Catalytic Reduction), which consists of a catalyst in which chemical reactions occur that selectively reduce environmentally harmful NOx gases to elemental nitrogen and water vapour.
BENEFITS OF SCR TECHNOLOGY
AdBlue is designed to be added to the exhaust gases of heavy vehicles, in an existing catalyst, to convert environmentally harmful nitrogen oxides (NOx) into elemental nitrogen and water vapour.
No. AdBlue is put into a separate tank from the diesel and is only intended to be added to exhaust gases emitted by heavy vehicles with SCR technology (Selective Catalytic Reduction).
SCR technology was developed by major heavy vehicle engine manufacturers in order to meet new EU limits on emission of polluting gases (EURO4 and EURO5), and consists of a ceramic catalytic converter that is added to the exhaust system, in which chemical reactions take place, with the aim of reducing NOx emissions.
The EU standards EURO4, EURO5 and EURO6 aim to limit the maximum levels of particulate and NOx emissions from heavy vehicle exhausts. The EURO4 and EURO5 standards have already been introduced and the EURO6 standard will become obligatory for all new trucks from 1st January 2014.
According to information from the main manufacturers, these engines allow a greater energy efficiency of diesel use, with the corresponding reduction in consumption. At the same time, this technology meets the requirements of the EURO4 and EURO5 standards. Furthermore, the system was widely tested in several countries and was shown to be a lasting and reliable solution.
To buy AdBlue you should contact ADP - Fertilizantes, Customer Support Department (SAC – 210 300 432).
AdBlue is available for bulk deliveries through dedicated cisterns with calibrated meters, in 1000 litre IBCs, in 200 litre bidons and in 10 litre containers, allowing for great versatility in the distribution of AdBlue, whatever the size of fleet and equipment that AdBlue customers have installed.
Stainless steel and PVC are the recommended materials. AdBlue should not be put in contact with copper, zinc, aluminium or normal steel, due to the risk of deteriorating the quality of the product and causing problems in the catalyst.
According to tests carried out by the CEFIC technical office, AdBlue will last for 1 year, as long as it is stored at temperatures between -5ºC and 30ºC, and as long as it is not directly exposed to different climatic conditions.
It is estimated that the consumption of AdBlue varies between 3% and 5% of diesel consumption.
Given that AdBlue only operates on the vehicle’s exhaust system the vehicle will continue to work normally, except that there will be very high levels of polluting emissions, at the level of a EURO1 engine. On more recent models, exhaust gas emissions are monitored and then registered on the OBD (On-board Diagnostic System). When higher than normal NOx emissions are detected, the vehicle’s power will be reduced, until the AdBlue situation has normalised. To avoid such situations it is advisable that each vehicle carries 10 litre containers, which will give the vehicle almost 500 km of autonomy, allowing the vehicle to be supplied with AdBlue until the next supply point
It is not expected that all filling stations will have AdBlue once the majority of vehicles come equipped with AdBlue tanks that allow autonomy for over 4500 km. There will, however, be a network of Filling Stations at the European level, which will guarantee supply in most situations.
There is no restriction in this situation, since AdBlue is only intended for use in exhaust systems.
