Weak Nitric Acid Production from Ammonia - Cost Analysis - NA E11A

Book excerpt: This report presents a cost analysis of Nitric Acid (65 wt%) production from ammonia. The process examined is a typical Medium Pressure process. In this process, ammonia is initially oxidized to nitric oxide at medium pressure (4 - 6 bar abs). Then, nitric oxide is oxidized to form nitrogen dioxide, and absorbed (at the same pressure) by water producing 65 wt% Nitric Acid. This report was developed based essentially on the following reference(s): (1) "Nitric Acid, Nitrous Acid, and Nitrogen Oxides," Ullmann's Encyclopedia of Industrial Chemistry, 2012; (2) "Nitric Acid ", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: Nitric Acid, Ostwald Process, Single Pressure, Medium Pressure, Ammonia Absorption, HNO3
