M.J. Cousins of Johnson Matthey and K. Nölker of thyssenkrupp Uhde discuss the integration of LCHTM technology and the uhde® ammonia process in providing low carbon ammonia at scale, efficiently, reliably and safely today.
Risk analysis tools such as hazard identification (HAZID), is often a first step in broader risk management and is especially valuable for green ammonia, where new technologies and processes introduce novel risks. This article explores various aspects of HAZID, from the basics of hazard identification to unique considerations specific to green ammonia facilities.
A review of papers presented at CRU’s Nitrogen+Syngas 2025 Expoconference, held in Barcelona from February 10th-12th 2025.
A European ammonia plant, has successfully restarted following a revamp of the process gas cooling section, executed by Casale. Casale replaced the outdated boilers located downstream of the secondary reformer with three new double-tube type boilers supplied by Arvos. The new boilers were installed in the same location as the previous ones, minimising investment costs and plant modifications. The more robust and reliable design of the Casale-Arvos boilers has resulted in enhanced overall performance and reliability of the ammonia plant.
Paralloy has developed Omega technology, an advanced reformer tube design that enhances heat transfer, gas turbulence, and process efficiency. Dr Dominique Flahaut of Paralloy explores the real-world implications of Omega reformer tubes.
Esben Sørensen and Glenn Rexwinkel of Plug Power review the safety aspects of integrating hydrogen production by electrolysis into existing ammonia processes. Novel safety risks associated with such changes are surmountable and the analysis presented shows that green ammonia production can be no more hazardous than traditional ammonia production.
New carbon capture-based plants could see US nitrogen capacity jump over the next few years, but Trump attacks on IRA tax credits may scupper some ongoing projects.
India’s push to replace its sizeable urea imports with home grown capacity continues, but may not keep pace with rising domestic demand.
Nitrogen+Syngas ’s annual listing of new ammonia, urea, nitric acid and ammonium nitrate plants.
Support for ammonia prices in markets east of Suez eroded during February. The ongoing bubble of support seen in NW Europe remained just about intact, though news of further declines at Tampa for March and slumping natural-gas prices should begin to eat away at any remaining support in the West. After declining $70/t during the first two months of 2025, the Tampa settlement between Yara and Mosaic was revised down a further $40/t for March, imposing further downward pressure on f.o.b. values in Trinidad and the US Gulf.
