In this report, the economic analysis concerns Concentrated Nitric Acid (99 wt%) production via two integrated units located in the United States. Initially, a typical Medium Pressure process produces weak nitric acid by ammonia oxidation and nitric oxide absorption; then nitric acid is concentrated by extractive distillation using sulfuric acid as dehydrating agent.
This study presents a feasibility analysis of Concentrated Nitric Acid (99 wt%) production from weak nitric acid (65 wt%) by extractive distillation using sulfuric acid as dehydrating agent. The economic analysis assumes a plant constructed in the United States.
In this report, it is approached the economics of Weak Nitric Acid (65 wt%) production from ammonia in a typical dual pressure process, assuming an industrial plant located in the United States. Initially, ammonia is oxidized to nitric oxide at medium pressure. Then, nitric oxide is oxidized to form nitrogen dioxide, and absorbed at high pressure by water producing nitric acid.
This report targets Weak Nitric Acid (65 wt%) production in the United States. Initially, ammonia is oxidized to nitric oxide. Then, nitric oxide is oxidized to form nitrogen dioxide, and absorbed at the same pressure by water producing 65 wt% Nitric Acid. The whole process examined in this study occurs at a high monopressure.
This report analyzes the economics of Nitric Acid production from ammonia via a typical Medium Pressure process in the United States. In this process, ammonia is initially oxidized to nitric oxide. Then, nitric oxide is oxidized to form nitrogen dioxide, and absorbed (at the same pressure) by water producing 65 wt% Nitric Acid solution as the final product.
