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.
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.

Gas availability and pricing continues to affect ammonia and methanol output from Trinidad, while Venezuela struggles with sanctions and political instability.
Tecnimont has been awarded a $1.5 billion contract by Nigeria’s Federal Executive Council to carry out rehabilitation works at the Port Harcourt refinery in Rivers State, run by the state-owned Nigerian National Petroleum Company (NNPC). The contract covers engineering, procurement and construction (EPC) activities for a full rehabilitation of the Port Harcourt refinery complex, aimed at restoring the complex to a minimum of 90% of its 210,000 bbl/d nameplate capacity. Tecnimont says that the project will be delivered in phases from 24 and 32 months and the final stage will be completed in 44 months from the award date.
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.
Reducing the carbon footprint in the synthesis of chemicals is a new global challenge as the world works towards providing sustainable products designed to minimise their environmental impacts throughout their whole lifecycle. This article looks at the role of blue technologies as part of a roadmap towards the decarbonisation of fuels and chemicals.
Copenhagen Infrastructure Partners (CIP) has unveiled plans to build Europe’s largest power-to-ammonia facility at the Danish port of Esbjerg, based on electricity from offshore wind turbines. The company said the plant will consist of 1GW of electrolysis capacity, capable of supplying sufficient hydrogen to produce 300,000 t/a of ammonia, and that the ammonia will be used as both as agricultural fertiliser and as fuel for the shipping industry. Excess heat generated in the process would be used to provide heating for around one third of local households in communities around the plant, to be sited on the west coast of Denmark. The company has signed a memorandum of understanding for the project with companies from both the agriculture and shipping sectors, including Danish Crown, Arla, DLG, Maersk and DFDS Seaways. CIP anticipates that it would cost approximately $1.2 billion to build the facility. They are currently seeking investors for the project and expect that the investment decision would be reached by 2023. The plant could enter commercial operations in 2026.
