Yara International has approved a project to partly convert its Pilbara plant near Karratha in Western Australia to green ammonia production.

Small, soft fruits such as blueberries, raspberries and strawberries thrive on fertile, well-drained soils rich in organic matter. Their nutrient needs can vary widely according to yield expectations and soil characteristics.

Topsoe has agreed to supply an initial 500 MW of industrial-scale, solid oxide electrolyser cells (SOEC) to First Ammonia, a US company aiming to produce green ammonia for transportation fuel, power storage and generation, as well as fertilizer, at sites in northern Germany and the southwestern United States. The companies envisage that over the lifetime of the agreement some 5 GW of SOEC electrolysers will be supplied, potentially replacing almost 5 bcm of natural gas and eliminating the emission of 13 million t/a of CO 2 emissions. The facility to manufacture the electrolyser cells will be built in Herning, Denmark, and has recently received a final investment decisions from Topsoe’s board.

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 at the Hyatt Regency in Chicago, USA, on 11-15 September 2022.

Maire Tecnimont’s innovation and licensing company Stamicarbon has been selected as the licensor for a urea project in sub-Saharan Africa, its first license in the region. Stamicarbon will deliver the process design package for the front-end engineering and design for a 4,000 t/d urea melt and granulation plant. The urea melt plant with a pool reactor will use Stamicarbon’s MP Flash design, a melt concept with improved energy efficiency, entailing a significant reduction of steam consumption. The minimal equipment items result in a significant reduction of the footprint and the overall capital cost of the plant. Less equipment also allows for a reduction in maintenance costs and OPEX savings.

As we near the end of the third quarter of 2022, the attention of the nitrogen industry is focused on the coming northern hemisphere winter, and the prospects for higher natural gas prices as temperatures fall and power and heating demands rise. Vladimir Putin has been stoking these worries to try and force a climbdown from European countries over the sanctions that followed his invasion of Ukraine, with the flow of gas through the Nordstream 1 pipeline across the Baltic Sea gradually dwindling over the summer and finally stopping altogether at the end of August due to “technical issues” – an explanation somewhat undermined by the subsequent statement from spokesman Dmitry Peskov that gas would flow again once sanctions were eased. This is a familiar enough tactic; Russia has used gas stoppages to pressure Ukraine and Europe several times over the past two decades.

Optimisation of the nitric acid process depends on good process visualisation tailored to the specific process parameters of the plant, improvements in combustion efficiency, reduction of N2 O emissions and the optimal use of platinum group metals.

The war in Ukraine has severely affected the supply of ammonium nitrate and CAN from Russia and Ukraine, with particular potential impact on Europe and Latin America. Can urea make up the difference?

A record rise in gas prices at the end of August triggered a spate of ammonia production curtailments across Europe. These included major shutdown announcements from CF Fertilisers UK, Grupa Azoty, Yara International and others.

T he high-price environment for fertilizers and other commodities, including natural gas, is having very different consequences globally.
