Nutrien has temporarily shut down one of the four ammonia plants at its Trinidad production site.

Nutrien is the world’s largest crop nutrient company with a market capitalisation of almost $20 billion (Figure 1). This fertilizer industry giant produces and distributes over 25 million tonnes of potash, nitrogen and phosphate products for agricultural, industrial and feed customers globally. The company’s agriculture retail business also serves over 500,000 growers worldwide through a network of international outlets.

Three large-scale phosphoric acid plants constructed as part of the world-class Umm Wu’al project in Saudi Arabia are now fully operational. James Byrd of Worley (formerly Jacobs ECR) describes the execution of the project from basic engineering through to plant performance tests.

The DA-HF phosphoric acid process has been successfully implemented at Grupa Azoty’s Police fertilizer production plant in Poland, as part of a revamp of the site’s existing DH plant. Sébastien Havelange and Alexandre Wavreille of Prayon Technologies outline the performance improvements achieved by this first-of-its-kind plant.

We profile the US ‘big three’ North American phosphate producers, Mosaic, Nutrien and Simplot, and disruptive market entrant Itafos.

Russia’s urea research & design institute, NIIK, introduces the Foam Hydrofilter – a completely new type of wet scrubber for air pollution control at urea plants. The Hydrofilter offers the same operational efficiency as many conventional scrubbing systems while avoiding many of their drawbacks.

We look at safety, health and environmental (SHE) management and hazards at nitrogen fertilizer plants and the importance of the International Fertilizer Association’s ‘Protect & Sustain’ certification scheme.

We look at state-of-the-art technology used in phosphate and potash mining, including equipment and systems for excavation, tailings thickening, transport, tunnelling and processing.

The International Fertilizer Association (IFA) is helping to fully develop the career potential of younger employees through its Young Professionals initiative. This is providing a new generation of industry professionals with access to mentoring and career development advice. It also gives individuals a chance to network with their peers, as well as subsidising attendance and participation at international conferences.

Concerns are growing about the health impacts of the heavy metals present in phosphate-based fertilizers and their accumulation in soils. In response, regulators and international agencies are currently seeking to limit human exposure to these potentially harmful elements. Encouragingly, a number of sustainable options with minimal market impacts are available, as Mikhail Pleschev, Boris Levin and Juan von Gernet of PhosAgro explain.
