Reagents for NOx Control

When choosing between SNCR and SCR systems to reduce NOx emissions, one of the first decisions to make is which reagent you will use for your NOx control system. It might be a complex decision, as you will need to consider the location of your facility, shipping requirements, source supply and back up options.

Today, we are the world’s biggest trader in ammonia and we operate with a network of 30 plants, 200 terminals and warehouses around the world. We will be happy to help you make the right decision.

Some key points to take into account when choosing reagent can be summarized as follows:

• What will be your estimated annual consumption of NOx control reagent?
• Can ammonia be delivered easily to your location?
• What competences exist in your plant for chemical handling?
• Can storage and handling training be made available?
• Will the storage be located close to a populated area or in an area where there is a high level of activity?
• What are the local and national regulations to consider when handling these chemicals?
