Concentrated Nitric Acid:

El Dorado Chemical Company produces high quality virgin white fuming, concentrated (>98%) nitric acid (HNO3) via the Uhde or direct strength nitric (DSN) process. Unlike NACSAC units that use sulfuric acid to concentrate weak nitric acid , the DSN process oxidizes NO2 and weak HNO3 under high pressures to produce concentrated nitric acid. Consequently, CNA produced from our DSN process does not contain the high sulfate concentrations that are inherent in CNA produced from a NACSAC process.

We are the largest producer of merchant concentrated nitric acid. We also own and operate the largest fleet of concentrated nitric acid rail cars in the United States allowing us to be responsive to your needs.
