OTS Group’s AdBlue storage advice
Fuel storage solutions provider OTS Group has offered guidance on the storage of AdBlue.
“AdBlue is corrosive to some materials such as copper and its alloys, and is very polluting to surface and groundwater,” said the company.
“In addition, contaminated AdBlue can cause costly damage to vehicles and equipment.”
The company cites guidance from the Environment Agency advising that those storing AdBlue should ensure: “your container, pipework and dispenser equipment are suitable for use with urea; you have secondary containment for the container and ancillary equipment; the dispensing area drainage is isolated from surface water drains; [and] you have a trigger nozzle with an auto shutoff to dispense AdBlue. Make sure that the nozzle cannot be left in the open position.”
The guidance adds that you should ensure: “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; and [ensure] you have an emergency plan and suitable training for dealing with spillages or other accidents.”
OTS Group advocates a ‘BSSM’ (bunded, specific, stable, managed) plan for the storage of AdBlue.
“Use double-skinned (bunded) tanks,” advised the company.
“Use a tank that is compliant with manufacturing standards. AdBlue should always be stored in a tank which has been specially designed for the task (compliant with ISO 22241, DIBT, BS EN ISO 9001:2008). This will help you to remain compliant and safeguard your business against increasingly strict environmental and emissions regulations as well as ensuring that the AdBlue doesn’t damage your fleet or machinery…
“AdBlue should be stored between 0-30°C. With a freeze point of -11°C, it’s important to use a tank that is built to withstand extremes of temperature in cold climates and to shield your tanks from direct sunlight to avoid overheating…
“It’s important to keep your AdBlue storage system well maintained. Selective catalytic reduction systems can be extremely vulnerable to contaminants, which can lead to expensive vehicle repair costs. We suggest getting professional advice when setting up your AdBlue storage system as well as using an in-tank monitoring system to stay on top of stocks and quality control.”
OTS Group’s suggested maintenance plan includes: putting equipment back in its original position after each use; inspecting gauges every week; inspecting the exterior of the tank, outlet and pipework every month; checking the bund alarm, electrical cables and warning labels every three months; checking the filter every three months and replacing if necessary; and checking the fixings and inner tanks and bund cavity every six months.
“OTS offers a variety of storage solutions including steel and poly tanks, catering to different needs and ensuring compliance with storage guidelines,” said the company.
“Whether you need a robust steel tank or a versatile poly tank, OTS has options to keep your supply secure and clean.”
Pictured are seven urea/AdBlue tanks, each with a capacity of 4,500 litres, prepared for delivery to a key client.
“Constructed from 316 stainless steel for the primary tank and mild steel for the bund, these tanks are designed to ensure durability and chemical compatibility,” said OTS.
“All internal and filling pipework is also made of stainless steel, highlighting the tanks’ high-quality specifications and readiness for shipment.”
The firm also offers regular service inspections and planned maintenance programmes to ensure AdBlue and fuel storage systems are always performing at optimal capacity.
