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.
