Sulphuric acid in rare earths processing
Global demand for rare earth metals is increasing, particularly for electric vehicle batteries and renewable energy devices, potentially leading to increased use of sulphuric acid in their extraction.

Sulphur markets suffered a correction in July-August that was more of a collapse; from $500/t to less than $100/t. Though it seems to have been something of an over-correction, and prices have moved back up since then, it is one of the most extreme price swings that sulphur has ever seen, comparable to the peak and precipitous fall in 2008. Indeed, at a time when commodity prices of all kinds have seen extremely high levels of volatility, sulphur has been more volatile still than just about all of them.
Fertilizers are always political to some extent, sitting as they do at the intersection of key commodities such as oil and gas on the one hand and food on the other. Markets for major nitrogen derivatives have often been distorted by political decisions to achieve self-sufficiency in fertilizer production, such as in, e.g. China or India. But over the past couple of months ammonia has found itself particularly in the political spotlight, in the context of the ongoing conflict in Ukraine, which continues to shape and indeed re-shape global commodity markets.
Casale has developed a range of methanol-ammonia coproduction processes to match different requirements according to product capacity.
The curtailment of ammonia production in Europe and reduction in export supply from Russia has led to an unprecedented year for the merchant ammonia market.
The latest improvements to melamine process technology now make it even easier to integrate a melamine plant with an ammonia and urea fertilizer complex. Guido Canti of Eurotecnica and Marc Wieschalla of thyssenkrupp Uhde discuss the benefits of plant integration.
Topsoe has made a number of changes to its board. Kim Saaby Hedegaard has been appointed as the company’s new Executive Vice President, Power-to-X. Hedegaard has served as interim Head of Power-to-X since May 2022. Before that, he held the position as Chief Operations Officer (COO). He joined Topsoe in 1999 and has since held various leadership positions within engineering, technology, and sales. Since 2017, he was responsible for Catalyst Production and Technology globally. He holds a MSc in chemical engineering from the Technical University of Denmark. He is replaced as COO by Andreas Bruun Jørgensen.
Fischer-Tropsch technology has long offered alternative production routes to synthetic fuels, but has struggled to make a use case outside of some niche applications. Could the greening of the chemical industry offer another way forward for the technology?
Catalysts are of crucial importance in a number of chemical processes and hence, their quality has a direct impact on the efficiency and operating costs of chemical plants. This refers especially to ammonia production, since this process is energy-consuming.
Maersk has ordered six more 17,000 teu (twenty-foot equivalent unit) container ships capable of running on methanol from Hyundai Heavy Industries (HHI). The order brings Maersk’s total order book of dual-fuel vessels capable of running on methanol to 19. Maersk said the new ships will replace existing tonnage in its fleet when they’re delivered in 2025. When all 19 vessels on order join the fleet and replace older tonnage, CO2 savings will be around 2.3 million t/a, according to Maersk. Maersk has committed itself to renewable methanol as a pathway to zero emissions shipping. Its first vessels are due for delivery from Q1 2024. The company has also signed several green methanol fuel supply agreements and joined a partnership to create the first e-methanol plant in Southeast Asia. Maersk is also working with Japanese trading house Mitsui and the American Bureau of Shipping (ABS), to jointly conduct a detailed feasibility study of methanol bunkering logistics in Singapore.
