    Nitric acid storage tanks can often be excluded from scheduled maintenance and recovery operations, especially when there is limited storage capacity and demand is high However, storage tanks can often produce high concentrations of spent precious metal catalyst (PGMs) This is the last point of recovery in the process stream and should beprocess, and (2) dualstage pressure process In the past, nitric acid plants have been operated at a single pressure, ranging from atmospheric pressure to 147 to 203 psia However, since Reaction 1 is favored by low pressures and Reactions 2 and 3 are favored by higher pressures, newer plants tend to operate a dualAP42 88 Nitric Acid Production US EPAThe DeNOx process was developed by BASF in the 60s and the V 2O 5 catalysts were developed in the 70s The catalysts are used for, but not limited to, the following applications: m Nitric acid plants m Power plants (coal, oil, gas, biomass) m Gas turbines m Gas and diesel engines m m Ship diesel m m Railroad engines m Glass trough m FCC unitsBASF: The right choice for nitric acid plants
