About Anhydrous Ammonia

Anhydrous Ammonia is a clear liquid at standard temperature and pressure with a very pungent and irritating odor. When mixed with air it can become flammable. Exposure to anhydrous ammonia can cause blindness, lung damage, burns, or death. Anhydrous Ammonia is the main source of nitrogen for plant growth. It is most widely used in agricultural crop fertilization. Anhydrous Ammonia is transported in pressurized tank cars with plug type angle valves.

Synonyms: Ammonia

Accidental Release of Anhydrous Ammonia

Powell Emergency Valve Closure Systems are designed to prevent significant releases of anhydrous ammonia. Exposure to even small quantities of this fluid can cause injury and even death. In the case of an accidental release, the ammonia emergency shutdown system will close the ammonia container valve within seconds, effectively stopping the release without any risk to personnel.

It is possible to prevent an accidental release of anhydrous ammonia. Contact us today to discuss your specific application requirements.
