Yara has applied for a new environmental permit in order to be able to import 275,000 t/a of ammonia by rail to its site at Tertre in the Saint-Ghislain municipality. The permit will cover ammonia to continue to operate downstream nitric acid and ammonium nitrate production at Tertre following the closure of the site’s 400,000 t/a ammonia plant. A public inquiry into the permit is expected to be completed in early September 2025. Yara says that train traffic to the site will increase to around 5 trains per week if the permit is granted.

Umicore’s latest research and development has resulted in a novel catalyst for the Ostwald process, aiming to enhance efficiency and sustainability in high-pressure nitric acid production.

The following case study describes a serious incident and the consequences of erroneously mixing nitric acid with hydrochloric acid. In Part 1 we report on the incident and the causes that led up to the event. In part 2 the impact, recommendations and lessons learned will be discussed.

Two fertilizer plants, formerly part of the Interagro Group, are being offered for sale by the liquidator, Sierra Quadrant. The factories, Ga-Pro-Co in Săvinești and Donau Chem at Turnu Măgurele, are available for direct negotiation starting at €17.8 million plus VAT and €18 million plus VAT, according to the liquidator, with a public auction to be held in September. Assets available include plants for the production of ammonia, urea, nitric acid, ammonium nitrate and liquid fertilisers, as well as transportation infrastructure for both road and rail.

There has been a release of nitrogen oxides from Austin Powder’s Red Diamond plant in Ohio. The company says that the decomposition of nitric acid caused the incident due to elevated temperatures inside a 5,000-gallon storage tank. This led to a visible release of nitrogen oxide gas, which was vented through the plant’s built-in safety […]

thyssenkrupp Uhde has been awarded a contract by Gujarat Narmada Valley Fertilizers & Chemicals Ltd. (GNFC) for the construction of a weak nitric acid plant in Bharuch, Gujarat state. The scope of work includes license, basic engineering, detailed engineering, procurement, construction, commissioning, and start-up services. The plant will have a capacity of 600 t/d of weak nitric acid, and will use Uhde’s proven EnviNOx® technology to reduce greenhouse gas emissions by eliminating nitrogen oxides from nitric acid production. This will be the third weak nitric acid plant licensed by Uhde to GNFC’s Bharuch site, in a partnership going back more than three decades.

Clariant's EnviCat N2O removal catalysts cuts 44,000 tons/month CO2e emissions at GNFC nitric acid plant in Gujarat, India

A review of papers presented at CRU’s Nitrogen+Syngas 2025 Expoconference, held in Barcelona from February 10th-12th 2025.

Nitrogen+Syngas ’s annual listing of new ammonia, urea, nitric acid and ammonium nitrate plants.

Orica says it has achieved a decarbonisation milestone by eliminating 1.0 million tonnes of carbon dioxide equivalent (CO2-e) from its Kooragang Island site, the equivalent of taking 600,000 cars off the road. The emissions reduction is the result of deployment of tertiary abatement technology on three nitric acid plants, in a project co-financed by the New South Wales Government’s Net Zero Industry and Innovation Program and the Federal Government’s Clean Energy Finance Corporation. The Clean Energy Regulator also approved the project as eligible to generate Australian carbon credit units.
