Other Nitrogen Products

Agricultural and industrial uses for nitrogen products abound. While ammonia, granular urea, UAN and ammonium nitrate typically account for the vast majority of our annual production, we do manufacture other nitrogen products that also meet growing customer demand. 

Diesel Exhaust Fluid

Diesel exhaust fluid (DEF) is an aqueous urea solution made with 32.5 percent high-purity urea (AUS 32) and 67.5 percent deionized water. DEF is used as a consumable in Selective Catalytic Reduction (SCR) in order to lower NOx concentration in the diesel exhaust emissions from diesel engines.
