Like the vital nitrogen fertilizer they handle, seasonal cheer will be in short supply for Europe’s ammonia producers and buyers this festive season, after many difficult months in which upward price trajectories showed no sign of slowing.
ACI will convene the 5th European Mineral Fertilizer Summit in London on 1-2 December 2021. Fertilizer International is proud to be a partner for this year’s event.
Rapidly escalating natural gas prices forced plant closures across Europe during September. Worst affected was the UK, where a fire at a cross-Channel electricity cable and low output from wind energy has, combined with low domestic storage capacity led to a surge in demand for gas for power stations and wholesale gas prices reached a record 350 pence per therm (equivalent to $46/ MMBtu) in October. On September 15th, CF Industries announced that it was halting operations at both its Billingham and Ince fertilizer plans due to high gas prices. Although ammonia prices have also risen, they have not kept pace with gas price rises, and there is a limit to what farmers could be expected to pay. CF CEO Anthony Will said: “$900 is the gas cost in a tonne of ammonia and the last trade in the ammonia market that was done was $700 a tonne”. As these plants supply most of the UK’s carbon dioxide for food and drink manufacture, the government said it would provide “limited financial support” to keep the Billingham plant operational, and that plant re-started on September 21st. Meanwhile, BASF closed its Antwerp and Ludwigshafen plants in Belgium and Germany due to what the company called “extremely challenging” economics. Fertiberia ceased production at its Palos de la Frontera site in Spain, and Puertellano remained down for scheduled maintenance. Yara shut 40% of its European ammonia production in September, and OCI partially closed its Geleen plant in the Netherlands. Achema in Lithuania decided against restarting its ammonia plant following maintenance in August, and OPZ in Ukraine shut one ammonia line at Odessa, with Ostchem and DniproAzot likely to follow. Borealis in Austria also reduced production.
Venkat Pattabathula, a member of the AIChE Ammonia Safety Committee, reports on the American Institute of Chemical Engineers’ Safety in Ammonia Plants and Related Facilities Symposium, held virtually on 30 August to 2 September 2021.
Arun Murugan and Mike Antony of FITIRI and Venkat Pattabathula of SVP Chemical Plant Services discuss the COORS Analytics system for more accurate prediction of the performance of a CO 2 removal system.
The European Union is seeking to create a climate-neutral and circular economy through its flagship Green Deal policy. The fertilizer industry can support these objectives by adopting inhibitor treatment technology (ITT) and controlled-release fertilizers (CRFs) based on biodegradable polymers. These two innovations have a vital role to play in improving nitrogen use efficiency and the shift towards more sustainable resource use, says Dr Matthias Potthoff of thyssenkrupp Fertilizer Technology.

While the covid pandemic has kept refinery run rates down in 2020, new refinery sulphur capacity will nevertheless form the bulk of new additions to sulphur production over the next few years. But delays to projects on both the supply and demand sides could tip a fairly balanced market in either direction.
February saw ammonia prices jump due to a series of plant outages, including EBIC in Egypt, and several plants in North America, including two on Trinidad; the 760,000 t/a Nutrien 4 plant and 500,000 t/a Tringen 2 plant, both due to gas shortages, as well as Yara and BASF’s 750,000 t/a unit at Freeport, Texas.
