Preliminary engineering work has started on a renewable powerto-fertilizer plant in Kenya.

In 2019, the EU fertilizer market was valued at around e17 billion, with France, Germany and former member state the UK together representing 40 percent of this total.

We highlight the large-scale nitrogen projects that are currently under development across the globe – with a focus on ammonia and urea technology licensors and engineering contractors.

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.

The heart of any urea plant is the high-pressure urea synthesis section. Properly functioning safety valves are vital to protect the high-pressure section against ruptures due to pressures that are too high in case of upset conditions. However, the very corrosive intermediate ammonium carbamate makes the reliable and proper functioning of safety valves more challenging.

Ammonia markets continue to be dominated by unplanned outages in Saudi Arabia (where the SAFCO 4 and one of the Ma’aden ammonia plants are both down, removing 2.3 million t/a of merchant ammonia from the market). This comes on top of other shutdowns earlier in the year on Trinidad, in the US and Australia.

Maire Tecnimont SpA says that its subsidiaries MET Development, Stamicarbon and NextChem have collectively begun work on a renewable power-to-fertilizer plant in Kenya. MET Development has signed an agreement with Oserian Development Company for the development of the plant at the Oserian Two lakes Industrial Park, on the southern banks of Lake Naivasha, 100 km north of Nairobi.

At a time when green (or maybe blue) ammonia is being looked to as a way of reducing carbon emissions, substituting for hydrocarbons in a variety of potential uses, a conference held at the start of June was a reminder that nitrogen, its neighbour on the Periodic Table, is by no means off the hook on the environmental front. The Eighth Global Nitrogen Conference – held over from last year because of Covid-19, and this year held virtually, as most events are for the time being – was the latest in a series of tri-annual meetings convened by the International Nitrogen Initiative (INI), with support from the UN Economic Commission for Europe (UNECE) and the German Ministry of the Environment. The INI grew out of the 1979 UNECE Convention on Long-range Transboundary Air Pollution and 1999 Gothenburg Protocol, and is concerned specifically with ‘reactive nitrogen’ (i.e. nitrogen not tightly bound to itself in a triple bond, which makes up 78% of the air around us).
