China's drive to reduce nitrous oxide (NOx) emissions will significantly increase demand for AdBlue additive over the next six years

A new report from global research company Integer, entitled "China Diesel Emissions & AdBlue Market Study 2011", predicts that demand for the NO_x-reducing diesel additive is set to soar, with consumption growing to between 4.1 and 7.4 million tonnes by 2017.  China currently consumes around 11,000 tonnes against Europe's 1.1 million.

Integer predicts that the exponential growth will be driven by the implementation of the China IV emission and fuel implementation standard.  Although some areas of China, such as Beijing, Shanghai and Hong Kong, are already ahead of schedule for China IV standards, the overall programme has been delayed until at least January 2012.

However, once the new standards come into force, the nation's massive heavy truck sector - which in 2009 pumped out some 2.1m tonnes of NOx emissions - will be transformed through selective catalytic reduction (SCR) technology and the use of AdBlue.

AdBlue Wiki Entry - Adblue decay and contamination

AdBlue is the registered trademark for AUS32 (Aqueous Urea Solution 32.5%) and is used in a process called selective catalytic reduction (SCR) to reduce emissions of oxides of nitrogen from the exhaust of diesel engined motor vehicles.
As the name AUS32 would suggest, it is a 32.5% solution of high-purity urea in demineralized water that is clear, non-toxic and is safe to handle. However, it can be corrosive for some metals, and must be stored and transported using the correct materials. The AdBlue trademark is currently held by the German Association of the Automobile Industry (VDA), who ensure quality standards are maintained in accordance with ISO 22241 specifications.^[1]
AdBlue is carried onboard SCR-equipped vehicles in specially designed tanks, and is dosed into the SCR system at a rate equivalent to 3–5% of diesel consumption. This low dosing rate ensures long refill periods and minimises the tank's impact on chassis space. On-highway SCR systems are currently in use throughout Europe, in Japan, Australia, Hong Kong, Taiwan, Korea, New Zealand and Singapore. The United States Environmental Protection Agency‎'s (US EPA) 2010 legislation will limit NOx to levels that will require North American trucks to be equipped with SCR post-2010. The current generic name in North America for AUS32 is diesel exhaust fluid (DEF). Some trucking industry OEMs have already developed branded SCR solutions, such as Daimler's BlueTec.
All European truck manufacturers currently offer SCR equipped models, and the future Euro6 emission standard is set to reinforce the demand for this technology. SCR systems are sensitive to potential chemical impurities in the urea solution, therefore, it is essential to maintain high standards of AdBlue quality according to the ISO 22241 standard.
The use of SCR technology in Europe made it necessary to develop an AdBlue supply infrastructure. AdBlue is available from thousands of service stations, this locator finder is updated monthly with new Retail sites selling AdBlue. It can also be purchased in canisters of 5 or 10 litres at service stations. Larger quantities of AdBlue can be delivered in, for example, 208 litres (46 imp gal; 55 US gal) drums, 1,000 litres (220 imp gal; 260 US gal) intermediate bulk container (IBCs), and bulk.

Truck operators caught out by tightening of emissions standards

Truck operators must take notice and act in good time to avoid being caught out by the forthcoming tightening of the emissions standards within the London Low Emissions Zone (LEZ); that’s the message coming from the manufacturers and exhaust system suppliers alike.

Costly Adblue Contamination Error for UK Haulier

During the past few weeks a large northern fleet operator discovered that their new Fleets NOx reduction system had become polluted.

The failed SCR injector had been polluted with oil.

The following investigation identified that the problem was caused by an operator using a non-dedicated container to transfer AdBlue from the IBC to the vehicle.  

The operative admitted to using a non approved-adblue container which had previously been used to top up engine oil and antifreeze and despite receiving a ‘quick rinse’ had led to contamination of the lines. Fortunately, the new magnum was the only truck to have received AdBlue from this container.

To confirm, AdBlue is highly susceptible to contamination and as little as 10ml of oil present in a 100 litre fill can corrupt the system causing irreversible damage.

adblue cure contamination

It only takes 5ml of diesel to 20 litres of AdBlue in the AdBlue tank to turn it into a harmful useless paste.  A problem that is any vehicles worst nightmere.  The first advice we would offer you is to not attempt to drive away.

In order to comply with new emission standards, the automobile industry has decided to introduce SCR technology to diesel -powered vehicles.

In nearly all cases the insurance industry will not pay out for misfuelling cases.

Thge AdBlue misfuelling cap has a build it system (including AdBlue magnet) which only opens when the AdBlue nozzle is inserted.

Safe storage and use of emission reduction

solutions (ERS) - e.g. AdBlue

　

1. Introduction

Stricter exhaust emissions for commercial vehicles with diesel engines, (buses, trucks, HGVs and coaches) have been issued by the EU, (Euro 4 in Oct 2005 and Euro 5 in 2008). To meet these standards the automotive industry has adopted several technologies. One is

ERS are stored at refuelling sites and are becoming a common feature at filling stations for commercial diesel vehicles and private depots. Vehicles will have an ERS tank, from which the solution is injected into the engine exhaust stream immediately after the combustion chamber. ERS consumption is between 4 and 6% of the diesel consumption. Selective Catalytic Reduction, where harmful exhaust gases are converted to nitrogen and water by catalytic conversion. AdBlue is a trade name for an emission reduction solution used for this process.

2. Storing and using ERS.

ERS are usually an aqueous solution of urea. If you store handle and use ERS according to manufacturers’ instructions and our guidelines, they pose minimal risk to operators and a limited risk to the environment. However, urea solution is very polluting to surface water and groundwater and has caused several serious pollution incidents from spills at farms where it was stored and used as a fluid fertiliser.

Because urea solution contains ammonia it’s corrosive to some metals, such as copper and its alloys. If tanks and pipework become corroded there is a higher risk of a spill that could cause pollution – which is against the law.

It’s important that ERS are stored in containers that are specifically designed and manufactured from materials that are suitable for use with urea. This also applies to all storage ancillary equipment, such as valves, dispensing nozzles and pipework.

Urea based ERS are soluble in water and should be kept out of surface water drainage systems discharging to the environment. They

3. Reduce the risk of causing pollution

Tank manufacturers are now producing storage solutions specifically for ERS. Steel and plastic storage systems with integral secondary containment are available. Some companies may supply specialist Intermediate Bulk Containers (IBCs) that are delivered full and then collected when empty. We recommend that you use storage and dispensing systems that are specifically designed for use with ERS.

You should make sure that:

1. Your container, pipework and dispensing equipment are suitable for use with urea.
2. You have secondary containment for the container and ancillary equipment.
3. The dispensing area drainage is isolated from surface water drains.
4. You have a trigger nozzle with an auto shutoff to dispense ERS. Make sure that the nozzle can’t be left in the open position.
5. You have appropriate emergency equipment to deal with large and small spills. For example, you could use proprietary spill kits, drain mats, pipe blockers, or permanent valves on drainage systems to provide containment.
6. You have an emergency plan and suitable training for dealing with spillages or other accidents. See Incident Response

AdBlue® misfuelling; the facts

Replacement of dosing, SCR and CAT units.

To prevent cross contamination we offer the worldwide patented AdBlue® Misfuelling Cap which only allows a 19MM gun entry.  Our solution comes with the AdBlue® magnet inbuilt.

The protection system consists of a ready mounted adapter that has been designed for the different sizes in adblue tanks.  The refilling neck comes in two diameters (58 and 77 mm).
We offer a cap solution for each diameter.

Only the correct AdBlue® refill pistol will fit into the opening - No access for diesel, gas, other pistols or contaminants.

For additional safety, there is a flap on the inside, which closes the opening.  It can be opened by the AdBlue® refill pistol.  The intergrated magnet releases the inserted AdBlue® refill pistol to refill the tank.  The upper part of the lid, fastened on a rubber band, closes the tank.

Iveco announces Euro VI engine line up with no EGR

Iveco and Fiat Powertrains have announced a Euro VI engine line which meets the emissions standards without using Exhaust Gas Recirculation (EGR). Instead the new engine range relies on Selective Catalytic Reduction (SCR) and a Diesel Particulate Filter (DPF) to meet NOx limits.
Fiat Powertrains' (FTP) new SCR technology will be introduced onto the new Cursor and Tector engine ranges for heavy-duty trucks and buses.
Alfredo Altavilla, Iveco Chief Executive Officer, said: "The technology that reduces fuel consumption and additional operating costs to their minimum is the correct technical choice. FPT Industrial's 'SCR Only' exhaust after-treatment fulfils this important need.
"It is clear that Euro VI vehicles will be more expensive; technology has a price and a value. We will introduce suitably equipped vehicles when our customers ask us to do so."
The new technology includes the following features, according to FTP:
• Optimised fluid-dynamics modelling of exhaust gas and AdBlue injection on SCR catalysts.• Feed forward control logic to enable precise AdBlue dosing in order to abate incoming sensed NOx emissions.
• Ammonia and NOx sensor technology for extremely accurate exhaust gas sensing, enabling adaptive AdBlue dosing to compensate for any ageing of the SCR catalyst.
• Insulated tube turbulence mixer technology to allow a homogeneous urea hydrolysis and distribution in the exhaust gas stream by introducing a swirling motion.
Euro VI emissions norms will apply to heavy-duty vehicles from the from 1st January 2014

AdBlue...detect diesel oil contamination in your truck's AdBlue tank

Anyway there was Biglorryblog, amiably chatting to a fleet engineer from a major truck rental company (begins with an 'F') and he mentioned the problems of people putting diesel in the AdBlue tanks. "You can't do it!" piped up another operator who was listening in to the conversation, before adding: "You can't get the diesel pump spout into the AdBlue tank filler neck--they're different sizes." My thoughts exactly....but my rental friend calmly came back with a sobering response..."You don't have to. You only need to stick the nozzle into the hole pull the trigger and the splash-back from the gun as the cut-out works still goes into the tank and it's enough to ruin the AdBlue..." Well I have to admit that was a new one on me

This is a point in case that shows just how sensitive the adblue solution is.
