German slurry handling specialist Vogelsang has just launched a new acidification technology which it claims will reduce ammonia emissions from agriculture, reducing up to 70% of ammonia to nutrient rich ammonium. Its new SyreN technology is an onboard sulphuric acid dosing system for tractors that treats slurry or digestate as it is applied to the land. It uses a front-linkage mounted unit to carry the acid, which also improves tractor weight distribution. The acid is dosed when the organic fertiliser is fed to the applicator, with a pH regulator automatically controlling and adjusting the flow. Nitrogen uptake of organic fertilizer is also increased by up to 1/3 as the ammonium is more easily metabolised by the soil. Results from a study in Germany showed that the acidifying slurry increased crop yield by up to 20%. The sulphur contained in the acid also becomes available to the plants as sulphate after spreading, eliminating the need for an additional pass over the field to administer a supplementary sulphur fertiliser, such as ammonium sulphate nitrate. At approximately 30 kg/ha, the amount of sulphur introduced into the crop with the SyreN system corresponds to the average amount of sulphur that is already applied to crops in the course of a growing season.

A look at papers presented at CRU’s annual Sulphur + Sulphuric Acid conference, which was once again held virtually, in November 2021.

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.

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.

Developments in sulphuric acid technology and engineering know-how are highlighted by recent project case studies from DuPont Clean Technologies, Metso Outotec and thyssenkrupp Uhde.

INEOS Enterprises has announced the completion of the sale of its Sulphur Chemicals business to International Chemical Investors Group, for an undisclosed sum. INEOS Sulphur Chemicals business is Spain’s largest dedicated manufacturer of sulphuric acid and oleum, serving clients in both agriculture and chemical intermediates via its 400,000 t/a plant in Bilbao. The business will become part of WeylChem’s advanced intermediates and reagents portfolio, which includes an existing sulphuric acid and oleum plant located in Lamotte, northern France. WeylChem is wholly owned by the International Chemical Investors Group (ICIG).

Production has begun at Ivanhoe Mines’ Kakula copper mine in the DRC. The company says that total production for this year is expected to be 80-95,000 t/a of copper in concentrate, with a phase two expansion to 400,000 t/a due to be completed by Q2 2022. Ivanhoe is working with China’s Zijin Mining on the development plan for phases 2 and 3 of the mine, as well as a feasibility study for the Kipushi zinc mine further to the east. Both projects lie close to the DRC’s southern border, with Angola and Zambia respectively. Phase 3 of Kamoa will lift capacity to an anticipated 600-800,000 t/a of copper in concentrate, making it the second largest copper mine in the world after Escondida in Chile. Canadian-based Ivanhoe expects to be digging 3.8 million t/a of ore at Kakula with 6% copper content in Phase 1.

The International Fertilizer Association (IFA) says that Svein Tore Holsether has been elected as its new chair of the Association. IFA said in its press release that the selection of Holsether, the president and CEO of Yara International, is a continuation of the industry’s commitment to sustainability.

The crushing and grinding of mined phosphate rock and potash ore is a vital preparatory step for subsequent beneficiation and chemical processing. Although often overlooked, the efficiency of downstream P & K fertilizer production is heavily reliant on successful particle size reduction upstream.
