Temperature dependent rate constants for the hydrolysis of CS2 and COS across Claus Al2 O3 and TiO2 catalysts are valuable tools for the design and optimisation of new, as well as existing, sulphur recovery units. In this context, Alberta Sulphur Research Ltd (ASRL) has measured CS2 and COS hydrolysis rates over a range of temperatures for both Al2 O3 and TiO2 catalysts under start-of-run and, more recently, end-of-run first converter conditions. In this article Christopher Lavery, Dao Li, Ruohong Sui, and Robert A. Marriott of ASRL report on their methodology and the utility of the kinetics calculated from their data and draw comparisons between the start-of-run and end-of-run results.

Reduced appetite for sulphur from processed phosphates producers in China will continue to place downwards pressure on pricing in the near term. l Phosphates-based demand is likely to remain low in the second half of 2022 as issues surrounding affordability persist, slowing import requirements.

The US refining sector continues to face operating pressures with 1.3 million bbl/d of closures in the past three years, while sour gas sulphur production has recovered somewhat. Meanwhile, demand from copper and lithium leaching projects will increase use of sulphuric acid over the next few years.

Meena Chauhan, Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.

After two years of virtual events, the CRU Sulphur + Sulphuric Acid 2022 Conference & Exhibition will return to an in-person event at the World Forum, The Hague, 24-26 October 2022. CRU will be welcoming the global sulphur and sulphuric acid community to this premier annual event for networking and essential updates on the markets and technical developments that are influencing the industry.

In a major blow to the British fertilizer industry, CF Fertilisers UK announced the closure of its Ince production site in north-west England in June (see p8). Ince is the UK’s largest compound fertilizer producer, operating three NPK+S units. It also manufactures large volumes of ammonium nitrate (AN) for Britain’s farmers. At the heart of the Cheshire complex is Ince’s long-standing ammonia plant. Unfortunately, high natural gas costs have kept this shuttered since September last year.

In increasingly volatile times for commodity markets, companies up and down the fertilizer supply chain are being left financially exposed to price fluctuations. Alison Coughlin and Tom Crane of CME Group explain how derivatives allow fertilizer market participants to protect themselves from the risk of adverse price movements.

Some 410 delegates from 208 companies and 45 countries participated virtually in the IFA Global Sustainability Conference, 28-31 March 2022. We report on the main highlights of this four-day event.

The overuse of limited natural resources and excessive contributions to climate change are just two of the criticisms currently levelled at global agriculture. Plant scientist David Marks is addressing these criticisms head-on through the company he founded, Levity Crop Science. He believes that, with better access to the right products, farmers can bring agriculture back into balance.
