Industrial demand for sulphur dioxide
Beyond its use in the manufacture of sulphuric acid, sulphur dioxide also has many industrial uses, especially in the food, paper, pharmaceutical and refining industries.

In spite of increasing environmental concerns over the use of coal as a feedstock, it continues to provide around one quarter of the world’s ammonia. But in a world that is decarbonising, is there still a future for coal-based capacity?
Sachin Nijhawan has been appointed as the new CEO of thyssenkrupp nucera US, and Juergen Grasinger was named Chief Operating Officer to advance the company’s international growth strategy and expand its global leadership in the manufacturing and supply of hydrogen production technology. Based out of the thyssenkrupp’s Houston office, Nijhawan will be responsible for the business activities of the US operations.
In recent years, extensive and severe internal attack has been observed of carbon steel equipment and lines in aqua ammonia service at several Yara manufacturing sites across the globe. In all cases, the damage has a distinct flow-accelerated corrosion (FAC) signature which challenges the current understanding of FAC. All features typically observed for this kind of damage mechanism, that seem to be specific to the NH3 recovery section of ammonia plant, are reported. Upgrading the material of construction for this unit, will solve this failure mode, but a leak would potentially generate health and safety problem for the release of ammonia.
One of the key challenges of producing RFNBO (renewable fuels of non-biological origin) compliant ammonia is managing the intermittency associated with renewable energy sources for hydrogen production. Furthermore, the additional costs associated with managing this intermittency can be significant. In this article, Dr Solomos Georgiou of AFRY Management Consulting explores those additional costs as well as potential ways to achieve cost savings and make RFNBO-compliant ammonia production competitive against conventional ‘grey’ ammonia.
Revamping aging urea plants with the latest urea technology brings many benefits. Not only can greenhouse gas emissions be reduced, but the overall performance and sustainability of these facilities can also be optimised. Hiroo Kunii of Toyo Engineering Corporation discusses TOYO’s approach to urea plant revamping.
We look at the future of polyhalite mining and its use as a fertilizer following Anglo American’s announcement that investment in its UK-Based Woodsmith mine will fall to zero in 2026 under current plans.
The ‘golden batch’ refers to stable periods at production plants that consistently generate high quality NPK products at high output. Yara’s Golden Batch digital tool digitises and stores past data from optimal production runs, making these easy to retrieve and implement again in future. Yara’s Marianne Ytterbø provides an overview of this novel digital tool, explains how it was developed, and highlights key benefits.
Significant changes to the level and location of sulphur inventory over the last two years have caused swings in short-term supply availability. Inventory plays a necessary role in balancing the sulphur market but exactly when, where, how, and why inventory enters the market can trigger a diverse range of price responses. In this insight article, CRU’s Peter Harrisson looks at how inventory change influences sulphur availability and pricing.
The dry bulk market is forecast to cool, after a year of high freight rates driven by demand shocks. Should ships return to the Red Sea during 2025, then the market will weaken even more. This development, explains BIMCO shipping analyst Filipe Gouveia, would particularly affect the supramax and handysize vessels typically used in fertilizer shipping.
