Which Reagent is best for me?

As the world leader in nitrogen chemistry, Yara is uniquely positioned to provide a reliable supply of NOx reduction reagents such as anhydrous ammonia, ammonia solution and urea solution. Yara can deliver the reagent of your choice from our extensive network of plants offering continuous sourcing back-up. Our product knowledge in urea and ammonia helps Yara bring the reagent into your processes in a safe and reliable manner.

Why Anhydrous ammonia could be for you:

Anhydrous ammonia is the total NOx reduction reagent and has advantages over ammonia solution and urea when lower NOx emissions are required.

With proper storage, correct handling and competence regarding ammonia properties, this reagent can be safely used to turn NOx into harmless nitrogen and water in your SCR system.

Why Ammonia Solution could be for you:

It is more efficient than urea and safer than anhydrous ammonia, offering a good compromise. The risks associated with the transport, storage and use of ammonia solution is significantly reduced compared to anhydrous ammonia as the ammonia is dissolved in water. This reduces the vapor pressure of the solution, which usually allows it to be stored at atmospheric conditions. Compared to aqueous urea solutions, ammonia solutions are more effective in terms of transportation and storage as 125% NOxCare ammonia solution contains 9,5% more nitrogen than 40% NOxCare Urea Solution Ammonia has advantages over urea when lower NOx emissions are required.

Why Urea could be for you:

You may wish to choose urea for safety reasons. It poses less risks in the workplace and doesn’t require specific training, unlike ammonia. Urea is non hazardous. It is stable, non volatile, non explosive and non flammable. It can be safely transported, stored and handled without the need for specific training, however, it is the least efficient of the 3 reagents offered.

Safety services

Ammonia is the ultimate, low cost SNCR and SCR reagent, and safe when handled correctly. As Yara is the world’s largest ammonia producer and trader, we have decades of experience in safe and professional handling of ammonia. We do therefore also know that incorrect handling, by any reason, may have severe consequences.

To ensure that ultimate safety is maintained at all times, from production to consumption, we train our employees and contractors extensively, and keep up to date with latest techniques and processes. We are happy to share this knowledge and competency with our customers.

We can offer a number of different safety related services, including:

  • Operator safety training or guidance
  • Manager level guidance and advice related to ammonia safety regulations, accident prevention, accident potential determination, and what to do if the unthinkable happens
  • Pre-delivery site inspections, ammonia delivery pre-requisites
  • Ammonia site safety assessment and recommendations
  • Ammonia safety guidance to customers during HESQ systems development and maintenance
  • Pre-audit or authority inspection preparations advice related to ammonia safety

Telemetry systems and safe storage for Ammonia Solution used for reducing NOx.

For peace of mind, Yara can offer to install telemetry systems on your storage facility. By using Yara’s telemetry system your reagent stock is constantly monitored remotely and Yara takes full responsibility to make sure your ammonia solution levels are always at the level set by you.
