China’s drive to build new battery production capacity for electric vehicles and stationary storage is leading to a familiar problem for the Chinese economy; overcapacity.

As environmental SO2 emission regulations become more stringent, tail gas treating options become limited. To potentially achieve lower opex and improved plot plan, utilising a biological desulphurisation process as an alternative to a conventional amine-based TGT unit is becoming of increased interest in the oil and gas industry. At the same time, demands for increased SRU capacity and reliability favour the use of medium and high-level oxygen enrichment.

Qatar construction services company UCC Holding has signed a memorandum of understanding with the Kazakh Ministry of Energy for a gas treatment plant at the Kashagan field with a capacity of 6 billion cubic meters as part of the Phase 2B expansion. The memorandum was signed by Minister of Energy Almassadam Satkaliyev and Mohamed Moutaz Al Khayyat, chairman of UCC Holding.

Falling volumes of sulphur from refining and sour gas could turn Europe into a sulphur importer.

In the final part of this two-part article, Michael Huffmaster , Consultant, presents case study results using a discrete reactor model incorporating heat, mass transfer, and activation reaction kinetics to assess the impacts of these variables on in-bed temperature profile and activation effectiveness. Tailoring gas rate, composition, and temperature progression can achieve in-bed exotherms which improve CoMo catalyst activation effectiveness for low temperature tail gas units.

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.

We report on the key highlights of the annual SulGas® conference, organised by Three Ten Initiative Technologies LLP,, which took place in Mumbai, India, from January 31 to February 2, 2024.

Sasol and Topsoe have appointed Jan Toschka as CEO of the joint venture established by the two companies to develop, build, own and operate sustainable aviation fuel (SAF) ventures and to market the products. Previously Toschka was president of Global Aviation for Shell, responsible for Shell’s global network of operations, joint ventures and sales of fuels, lubricants and sustainable solutions to the aviation industry. During his tenure at Shell, he has led teams across sales, mergers and acquisitions, trading, and retail businesses globally, spanning various industries including Marine and Retail. Toschka will assume his new role as CEO on 1 March 2024 and the joint venture will be launched during the same month. The new company will be headquartered in The Netherlands.

Already the world’s largest exporter of sulphur, Abu Dhabi continues to expand its sour gas production and sulphur output.
