Anhydrous ammonia means undiluted ammonia. It can be used directly with SNCR and SCR systems either in the gaseous form (most common) or it can be injected in the liquid state. Anhydrous ammonia is usually stored under pressure (5-10 bar) or it can be stored at atmospheric pressure if kept at -33°C.
Yara is a world leader in supply and safe transport of ammonia in different states, with one third of the ammonia traded around the world coming from Yara. Anhydrous ammonia is a hazardous material, but it can be handled safely by using equipment designed for this product and by correct storage.
This requires following safety rules and legislation, which Yara can help you to include in your staff training for handling and storing ammonia at your site.
