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.

Producing efficient fertilizers that deliver nutrients directly to crops in exactly the right amounts has clear economic and environmental benefits. Recent advances in controlled-release and stabilised fertilizer technology are highlighted.

ICL has developed a new generation of rapid biodegradable coatings for its controlled-release fertilizer (CRF) portfolio. The new coating technology reduces the environmental footprint of CRFs and will help farmers meet the requirements of Europe’s Green Deal. This patented innovation, named eqo.x, coats nitrogen fertilizers for field grown crops. Eqo.x has already been fully tested in the field – and shows excellent results in terms of production, nutrient use efficiency, volatilisation and leaching reduction. Ronald Clemens, ICL Global Marketing & Portfolio Manager CRF, explains the benefits.

The Broadfield process has remained a mainstay of the global phosphate industry since its introduction in the 1930s. Ian Hancock, vice president sales & operations, Bradley Pulverizer, explains it continuing success in superphosphate production worldwide

The drive for ever higher crop yields is shifting the focus onto secondary nutrients such as calcium and magnesium. In this article, we look at the role of magnesium and calcium in crop nutrition and the main fertilizer product options.

Effective and efficient wastewater management is a vital task that is being aided by the introduction of new treatment technologies. The recovery of economically-valuable nutrients from wastewaters is another priority.

Saudi Aramco has confirmed a phased development approach for its $100 billion-plus Jafurah unconventional onshore gas project, which is expected to produce up to 2 billion cubic feet per day of gas by 2030, raising the company’s overall gas production capacity by 50% over that time frame. Aramco says that the first development phase for the Jafurah gas plant is likely to come on stream by 2025, and it is progressing with the phased development of a project that will reach a raw gas processing capacity of 3.1 bcf/d.

Inshan S. Mohammed of Sulfur Recovery Engineering shares lessons learned from a recent SRU shutdown assistance programme involving an error with the tags used within the BMS system installed on a direct-fired reheater.

Marco van Son and Frank Bela of Comprimo share lessons learned from SRU war stories, including: inadvertent NH3 destruction in an oxidising atmosphere, rich amine emulsion, SWS fixed valve trays, H2 spiking of SRU feed, rich amine flash drum early warning, V-ball fuel gas safety shutoff valves, TGTU methyl mercaptan, and commissioning and Murphy’s Law.
