Reagents used in SCR and SNCR systems for NOx reduction
When choosing between an SCR and SNCR system to reduce NOx emissions, one of the first decisions to make is the choice of the reducing agent to be used in your system for NOx control.
This can be a complicated decision as you must take into account several parameters:
- The location of your site
- The reagents delivery costs
- The suppliers of reagent nearby as well as the possible sources of back-up.

There are some important criteria to consider when choosing the type of reagent that suits you best:
- What is your anticipated annual consumption of NOx reagent?
- Can ammonia be easily delivered to your site?
- What is the level of knowledge of your staff in terms of handling chemicals?
- Can training on storage and handling of chemicals be implemented?
- Will the storage site be in a residential area, or a site with lots of activity?
- What are the norms and local or national legislations regarding the handling of these chemicals?
