Heat recovery systems at sulphuric acid plants have been providing carbon-free energy for decades now and continue to improve. There is also potential to combine the clean power generated at acid plants with hydrogen production from water electrolysis. This could provide the basis for green fertilizer production.
The Jordan Phosphate Mines Company (JPMC) has signed a supply agreement with Germany’s LUMA-International Company.Under the terms of the agreement, JPMC will sell 850,000 t/a of phosphate rock to the German company at international market rates. The agreement was signed by JPMC CEO Abdulwahab Rawad and managing director of LUMA-International Ralf Keller, in the presence of JPMC Chairman Muhammad Thneibat. Thneibat expressed hope that the deal would open wider scopes of cooperation between the JPMC and German companies in the field of phosphate fertilizers, and Keller likewise said that his company was looking forward to more cooperation with the JPMC and new partnerships to produce phosphoric acid and phosphate fertilizers.
A sulphuric acid plant forms critical material and energy interfaces with other plants in several different types of chemical and metallurgical complexes. Shailesh Sampat of SNC-Lavalin discusses how the acid plant design is customised to match the product mix and the energy requirements of the complex to provide the optimum solution for energy and material requirements.
EuroChem Group recently completed the purchase of the Serra do Salitre project from Yara International for $452 million. This one million tonne capacity Brazilian phosphate project is due to be completed in 2024.
DuPont has agreed to sell its Clean Technologies business for $510 million to an international private equity consortium, comprising BroadPeak Global, Asia Green Fund and The Saudi Arabian Industrial Investments Company (Dussur). The new, independent company has been named Elessent Clean Technologies and will be a global leader in process technologies to drive sustainability and carbon neutrality in the metal, fertilizer, chemical and oil refining industries. Elessent retains exclusive rights to the technologies, expertise, products, and services including: MECS® sulphuric acid and environmental technologies, BELCO® scrubbing technologies, STRATCO® alkylation technology and IsoTherming® hydroprocessing technology. Derived from the words “element” and “essential,” Elessent says that it will help customers produce, optimise or separate essential elements every day, creating clean alternatives to traditional industrial processes to minimise the impact on the environment while enabling our customers to produce essential elements critical to everyday life.
Fertilizer International presents a global round-up of phosphate rock, phosphoric acid and finished phosphates projects.
Phosphate manufacturing is being enhanced thanks to process integration, digitalisation and other advances.
The feed phosphates industry is caught between conflicting trends currently, according to Alberto Persona of the Fertecon fertilizer team at IHS Markit. While the long-term demand-side fundamentals look broadly stable, there is still likely to be a fight for market share due to competition from substitute products and the emergence of new projects.
Lithium-boron miner ioneer Ltd has awarded DuPont Clean Technologies a contract for the license, engineering, and supply of proprietary equipment for a planned sulphuric acid plant at the company’s Rhyolite Ridge project in Nevada. DuPont will work with engineering partner SNC-Lavalin on the plant design, using MECS® sulphuric acid technology for the 3,500 t/d sulphur-burning unit, as well as controls that limit emissions to among the lowest in the world for this type of facility. DuPont will also supply its latest generation MECSSuper GEAR® ™ catalyst and other critical proprietary equipment. The contract is conditional on a final investment decision by the ioneer board of directors.
Th e past year has seen an extraordinary run-up in sulphur and sulphuric acid prices, the former from a low of around $50-70/t f.o.b. in mid-2020 to more than $100/t higher than that at the end of Q1 2021. Prices then plateaued for much of this year, but they have begun moving inexorably upwards again in the past couple of months, drawn by rapidly rising phosphate prices, and Middle East sulphur rates recently breached price levels not seen since 2012.
