Lithium ion battery production is driving major expansions in nickel and cobalt extraction, but lithium iron phosphate (LFP) battery use is growing rapidly.

Leading companies such as Ballestra, Buss ChemTech, Elessent Clean Technologies (MECS) and Prayon Technologies are working together to solve the numerous production challenges facing the operators of integrated phosphate fertilizer production plants.

The centre of gravity of the phosphate industry continues to shift, with Chinese exports less important, and fresh demand coming from India and Brazil.

In this review article, Hatch’s Jayden Ladebruk, Lyndsay Tran, Amelia Parrenin, and Edward DeRose outline the wide range of phosphoric acid production technologies, and discuss how industry challenges are influencing the choice of phosphoric acid process.

PhosAgro’s shareholders elected a new board of directors during the company’s annual general meeting (AGM), held on 24 March. The new board includes: Viktor Ivanov, Yuriy Krugovykh, Siroj Loikov, Natalia Pashkevich, Mikhail Rybnikov, Alexander Seleznev, Vladimir Trukhachev, Viktor Cherepov, Alexander Sharabaiko and Andrey Sharonov. The AGM also approved the company’s annual report for 2022, which reflected total production of 11.1 million t/a of agrochemical products (up nearly 5% year-on-year); and a one-third increase in investments to develop the company. PhosAgro CEO Mikhail Rybnikov said: “The consistent implementation of our long-term development programme enabled us to increase production last year, and we remained the leader in terms of the total supply of all types of fertilizers to the domestic market and expanded our support in the social sphere considerably. We intend to maintain this momentum of steady development. In 2023, we expect further growth in the production of agrochemical products, to 11.3 million tonnes. Our workforce laid the groundwork for this in January-February, as we increased production of phosphoric acid and sulphuric acid by 22% and 17% year-onyear, respectively, over this period.”

Evaporation and crystallisation are widely used throughout the fertilizer industry. These powerful production processes are helping fertilizer manufacturers diversify their product portfolios, improve profitability and meet sustainability goals.

Blended and compound NPK fertilizers are a mainstay of many markets globally. We review the main production technology options.

Arafura Rare Earths Ltd has awarded Worley subsidiary Chemetics Inc the contract to install Chemetics CORE-SO2™ sulphuric acid technology at its Nolans Project in the Northern Territory of Australia. The scope of the contract is to deliver the detailed engineering and supply of the sulphuric acid plant plus associated oxygen plant on a lump sum basis. The acid plant at Arafura’s Nolans Project will be designed to meet future emission performance and clean energy transition goals, utilising CORE-SO2’s high turndown capability and the potential to idle the plant while keeping the catalyst warm for extended periods of time, allowing the acid plant to operate with 95% reduced SO 2 emissions when compared to traditional double contact double absorption (DCDA) plants. High pressure steam production within the process will allow CO 2 - free electrical power to be generated. By removing the use of a diesel or natural gas start-up burner, further greenhouse gas emissions will be prevented.

Fertilizer International presents a global round-up of phosphate rock, phosphoric acid and finished phosphates projects.

The International Fertiliser Society (IFS) has launched FerTechInform, a comprehensive online technical resource for fertilizer production. The new digital resource combines an information knowledge base with an interactive forum for users. IFS Secretary Steve Hallam explains how it works, who it is for, and why it came into being.
