Nitric acid is a vital industrial chemical widely used in fertilizers, explosives, dyes, pharmaceuticals, and metal processing industries. With rising demand from agriculture and chemical manufacturing sectors, setting up a nitric acid production facility has become a strategically attractive investment. This Nitric Acid Manufacturing Report offers a comprehensive overview of production economics, market drivers, manufacturing processes, feedstocks, and return on investment to help stakeholders make informed decisions.Introduction to Nitric Acid Manufacturing
Nitric acid (HNO3) is a highly corrosive mineral acid primarily produced through the oxidation of ammonia. It plays a crucial role in the production of ammonium nitrate fertilizers, adipic acid, nitrobenzene, and various intermediates used in industrial chemistry. Growing agricultural output, infrastructure development, and industrialization particularly in emerging economies are accelerating demand for nitric acid globally.
A well-structured nitric acid manufacturing plant requires advanced process technology, efficient utilities management, reliable raw material sourcing, and strict adherence to safety and environmental norms.

Feedstocks and Raw Material Requirements
The primary feedstock for nitric acid production is anhydrous ammonia, which is reacted with air (oxygen) under controlled conditions. Key raw materials and utilities include:
Anhydrous ammonia
Atmospheric air
Water (for absorption and cooling)
Electricity and steam
Cooling water
Availability and pricing of ammonia significantly influence production economics. Hence, proximity to ammonia suppliers or integration with ammonia manufacturing units can enhance cost efficiency.
Nitric Acid Manufacturing Process
Commercial nitric acid is produced using the Ostwald process, which involves three main steps:
Ammonia Oxidation: Ammonia is oxidized over a platinum-rhodium catalyst at high temperature (around 850–900°C) to produce nitric oxide (NO).
Nitric Oxide Oxidation: Nitric oxide reacts with oxygen in the air to form nitrogen dioxide (NO2).
Absorption in Water: Nitrogen dioxide is absorbed in water inside absorption towers, forming nitric acid of varying concentrations.
Advanced plants use tail gas treatment and heat recovery systems to improve energy efficiency and reduce emissions. Modern nitric acid units are designed to meet stringent environmental regulations while maximizing yield.
Cost Model and Operating Economics
The cost structure of a nitric acid manufacturing plant can be broadly divided into capital expenditure (CAPEX) and operating expenditure (OPEX).
