Book excerpt: This report presents a cost analysis of Concentrated Nitric Acid (99 wt%) production from ammonia. The process examined comprises two integrated units: a typical Medium Pressure process for weak nitric acid production; and a typical Sulfuric Acid concentration process for Concentrated Nitric Acid (99 wt%) production. In this process, ammonia is initially oxidized to nitric oxide at medium pressure (4 - 6 bar abs). The nitric oxide is oxidized to form nitrogen dioxide, and absorbed (at the same pressure) by water producing 65 wt% Nitric Acid. Then, weak nitric acid (65 wt%) is concentrated up to 99 wt% Nitric Acid by extractive distillation using sulfuric acid as dehydrating agent. This report was developed based essentially on the following reference(s): Keywords: Nitric Acid, Ostwald Process, Single Pressure, Medium Pressure, Ammonia Absorption, HNO3, Sulfuric Acid Process, Strong Nitric Acid, Dehydration
