Downstream phosphate production is expected to climb, with further sulphur price recovery expected. Overall, global demand remains lacklustre as downstream demand has yet to increase substantially in key markets and sulphur availability from most origins is ample.
Elessent Clean Technologies introduces the MECS digital advisor, a web-based dashboard for plant performance assessment, troubleshooting and a supplemental mentoring tool for less experienced engineers and operators.
Digitalisation is making a strong impact in the process industry and is providing an opportunity to have a positive impact on the production KPIs. Metso’s Metals & Chemical Processing Business reviews the impact of digitalisation in the sulphuric acid industry today and discusses the concept of a future pit-to-port system within a digital eco-structure.
The implementation of WSA technology to recover sulphur as sulphuric acid from lean sulphurous off-gases offers significant environmental benefits. These include waste reduction, resource efficiency and reduced overall CO2 e footprint, while also producing profitable sulphuric acid. By embracing such practices, industries can ensure improved or better consumption and production patterns and foster a more sustainable and responsible future. J. Feddersen and S. S. Johansson of Topsoe illustrate these benefits using three distinct industrial applications where WSA technology provides a smarter way to treat sulphurous off-gases. It is not only waste stream management in the three cases, but also reduced transportation of chemicals, reduced opex and reduced CO2 e footprint.
Sulphur prices reached a low point in mid-February, with buyers looking to the tender from Muntajat as well as the return of Chinese buyers following the Lunar New Year holiday for the direction that the market would turn. CMOC’s 5 February tender for 40,000 tonnes of sulphur for early-April arrival was indicated awarded in the upper $90s/t c.fr on supply from the FSU, though details were not confirmed.
The phosphate industry, the dominant consumer of sulphuric acid worldwide, has grown to its present size on the back of fertilizer consumption. And while this has seen considerable growth over the past decades, especially in countries like China, India and Brazil, it has generally been fairly steady and – subject to the annual vagaries of weather and the commodity cycle – relatively predictable. However, the world economy is now in the throes of a major transformation towards less carbon intensive generation and use of energy, and that is disrupting many markets, including that for phosphates.
In January, Kazakh uranium producer Kazatomprom warned of potential adjustments to its 2024 uranium production due to challenges with sulphuric acid availability and construction delays at new uranium mining operations. In a statement the company said that its projected uranium output for 2024 will be between 21,000 t/a and 22,500 t/d U3 O8 , around 20% lower than the amount it had been expecting to be able to mine. Kazatomprom’s uranium output was 21,100 t/a U3O8 in 2023, down 1% on 2022 figures, with output flat during 4Q 2023. While it said it had sufficient inventory in stock to cover contracted deliveries in 2024, there could be problems for 2025 deliveries.
CRU expects sulphur prices to be supressed in early 2024 by high port inventory and limited phosphate export business. However, affordability continues to support raw materials purchases and leaves room for price increases, especially if downstream production picks up as expected and sulphur stock drawdown slows.
Freeport Indonesia has inaugurated the $250 million expansion at its PT Smelting copper smelter in Gresik, East Java, in a ceremony attended by Indonesian president Joko Widodo. Smelting, a joint venture between Freeport McMoRan and Mitsubishi Materials, has increased copper concentrate processing capacity to 1.3 million t/a, up from the previous figure of 1.0 million t/a, with copper cathode production of 300,000 t/a.
With increased demands to reduce SO2 emissions and lower energy consumption, Clark Solutions highlights the advantages of single absorption sulphuric acid plants compared to double absorption plants.
