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.

A foundation laying ceremony attended by Qatar’s Deputy Amir Sheikh Abdullah bin Hamad Al Thani has been held at Qafco’s new blue ammonia facility at Mesaieed Industrial City on Qatar’s east coast. The plant, which is scheduled to be completed in 4Q 2026, will be the largest blue ammonia facility in the world. Speaking at the ceremony, energy minister Saad Sherida Al-Kaabi said the facility will have a capacity of 1.2 million t/a, along with CO2 injection and storage facilities with a capacity of 1.5 million t/a. QatarEnergy will also provide the new plant with more than 35 MW of electricity from the solar power plant currently being built in Mesaieed. Completion of the complex will see Qatar become the world’s largest exporter of urea, producing 12.4 million t/a, according to Qafco.

Based on 16 years of experience, Muhammad Nabeel Shakir of Fatima Fertilizer Company outlines a methodology to achieve optimum performance of the PGM catalyst and catchment system in nitric acid plants.

Stefano Cicchinelli and Carmen Perez of Stamicarbon (MAIRE) explore the latest advancements in tertiary abatement technologies, their implementation in nitric acid plants, and the implications for the fertilizer industry.

The nitric acid industry has made great strides in reducing nitrous oxide emissions over the past few decades, but emissions from agriculture due to nitrogen fertilizers remain a problematic source of N2 O in the atmosphere.

As the industry pushes towards more sustainable practices, ammonia is emerging as a promising alternative fuel for ships. Effective management of by-product NOx, NH3 and N2 O emissions from the combustion of ammonia is crucial to the success of ammonia as an alternative fuel. A new catalyst has been developed by Enercat to treat these three molecules in one bed. Jean-Rémi Stephany and Emmanuel Rohart of Enercat – Alsys Group report on this new technology which has been developed in marine ammonia combustion engine conditions.
