Our process is fully compliant with ISO 9001 quality management standards.

Catalytic Oxidation of Ammonia

High-purity anhydrous ammonia (NH₃) is mixed with filtered, compressed air and passed over a platinum-rhodium (Pt-Rh) catalyst gauze at high temperatures (850-950°C). This exothermic reaction converts ammonia to nitric oxide (NO).

→

Oxidation of Nitric Oxide

The resulting nitric oxide gas is cooled and then mixed with more air. This spontaneously oxidizes the nitric oxide (NO) into nitrogen dioxide (NO₂), a crucial intermediate step.

→

Absorption in Water

The nitrogen dioxide (NO₂) gas is fed into absorption towers where it reacts with deionized water in a counter-current flow. This reaction forms nitric acid (HNO₃) and regenerates some nitric oxide, which is recycled back into the process.

Key Process Highlights:

Material Integrity: We use specialized stainless steel alloys (like 304L and 310S) and borosilicate glass for reactors and piping to withstand the highly corrosive nature of nitric acid, ensuring product purity and a long equipment service life.
Advanced Catalysts: The use of high-efficiency Pt-Rh catalyst gauzes maximizes conversion rates and minimizes catalyst loss, making our process both cost-effective and environmentally responsible.
Stringent Quality Control: In-line sensors continuously monitor temperature, pressure, and gas concentrations. Final product is rigorously tested using methods compliant with ANSI and ASTM standards to verify concentration and purity.
Energy Efficiency: Our plants incorporate heat recovery systems that capture the heat generated during the exothermic ammonia oxidation. This recovered energy is used to generate steam, powering turbines and reducing the overall energy footprint of our operations.

Diverse Applications: Where Our Nitric Acid Makes a Difference

Nitric acid is a versatile and essential chemical utilized across a vast spectrum of industries. Its unique properties as a strong acid and powerful oxidizing agent make it indispensable. As a premier nitric acid supplier, we cater to all these sectors.

Secure and compliant packaging for various grades of nitric acid.

Agriculture & Fertilizers: The largest application by far. Our nitric acid is a key raw material for producing ammonium nitrate and calcium ammonium nitrate, high-nitrogen fertilizers that are vital for crop yields and global food security.
Chemical Synthesis: It's a fundamental building block for the organic chemical industry. It is used in the production of adipic acid (a precursor to Nylon 6,6), toluene diisocyanate (TDI for polyurethane foams), and various nitro-compounds like nitrobenzene.
Metallurgy and Mining: Used for metal passivation, etching, and cleaning of metals like stainless steel and aluminum. In its most reactive form as part of *aqua regia* (a mixture with hydrochloric acid), it is one of the few reagents that can dissolve noble metals like gold and platinum.
Explosives Manufacturing: Nitric acid is used to synthesize a wide range of nitrated explosives, including nitroglycerin, trinitrotoluene (TNT), and cyclotrimethylenetrinitramine (RDX), for both industrial and military applications.
Rocketry: Red Fuming Nitric Acid (RFNA) is used as a hypergolic oxidizer in rocket propulsion systems, prized for its high density and ability to spontaneously ignite upon contact with certain fuels.

Frequently Asked Questions (FAQ)

To help you make an informed decision, we've compiled answers to some common questions about our nitric acid products and services. We believe in transparency and providing all the information you need, reinforcing our position as a trustworthy nitric acid supplier.

1. What are the different grades of concentrated nitric acid you offer?

We offer a wide range of grades, including Technical Grade (typically 60-68%), Concentrated or Azeotropic Grade (~68-70%), and Fuming Grades such as White Fuming Nitric Acid (WFNA) and Red Fuming Nitric Acid (RFNA), which have concentrations exceeding 86%. We can also create custom concentrations to meet your specific process requirements.

2. What safety precautions are necessary when handling nitric acid?

Nitric acid is a highly corrosive and strong oxidizing agent. Proper handling is critical. Always use appropriate Personal Protective Equipment (PPE), including acid-resistant gloves, chemical splash goggles, a face shield, and a chemically resistant apron or suit. Work in a well-ventilated area, preferably under a fume hood. Refer to the Safety Data Sheet (SDS) provided with every shipment for detailed information. We also offer safety handling consultation.

3. What materials are compatible with storing concentrated nitric acid?

Material compatibility is crucial to prevent dangerous reactions and container111 failure. Recommended materials include high-density polyethylene (HDPE), polypropylene (PP), certain fluoropolymers like PTFE and PFA, and specific grades of stainless steel (e.g., 304L, 316L) under specific conditions. Materials like carbon steel, aluminum, copper, and most plastics are not suitable and will be rapidly corroded.

4. How do you ensure the quality and purity of your nitric acid?

Our quality assurance is multi-layered. We begin with high-purity raw materials and a tightly controlled ISO 9001-certified manufacturing process. We employ continuous in-process monitoring and conduct rigorous final product testing in our advanced laboratory. Each batch is tested for concentration, specific gravity, and trace impurities using methods like titration and ICP-MS. A detailed Certificate of Analysis (CoA) accompanies every order.

5. What is the difference between white fuming nitric acid (WFNA) and red fuming nitric acid (RFNA)?

Both are highly concentrated forms of nitric acid. WFNA is essentially pure nitric acid (>97.5%). RFNA contains a significant amount of dissolved nitrogen dioxide (NO₂), typically up to 27%, which gives it a reddish-brown color. The dissolved NO₂ acts as an inhibitor, reducing corrosion on metallic storage tanks, and also makes RFNA hypergolic (self-igniting) with certain rocket fuels, making it a valuable propellant oxidizer.

6. Can you provide a Certificate of Analysis (CoA) with each shipment?

Absolutely. Trust and transparency are paramount. Every single batch of nitric acid we ship is accompanied by a specific Certificate of Analysis (CoA). This document details the exact test results for that batch, including concentration, density, and levels of key impurities, assuring you that the product meets or exceeds the agreed-upon specifications.

7. What are your standard packaging and delivery options?

We offer flexible packaging to suit different scales of operation. Standard options include UN-approved 35kg or 250kg HDPE drums, 1-1.5 ton IBCs (totes), and bulk delivery in dedicated ISO tankers. We work with certified hazardous material carriers to ensure safe, compliant, and timely delivery to your facility anywhere in the world.
