Continuing growth in Chinese ammonium sulphate production is leading to a continuing flood of exports, as greater awareness of the utility of sulphur as a fertilizer leads to increasing global demand.

India’s phosphate production is using increasing volumes of sulphuric acid, but new domestic smelter and sulphur burning acid capacity may mean reduced imports in future.

NextChem has been awarded two contracts to upgrade and expand the capacity of the Heydar Aliyev Oil Refinery (HAOR) industrial complex in Baku by state oil company SOCAR. As part of the contract, NextChem will conduct a technological assessment and deliver a process design package to upgrade the existing sulphur recovery unit (SRU) with oxygen enriched air, a cost-effective and flexible solution for expanding its current sulphur production capacity. Additionally, NextChem will provide the licensing and the process design package based on its proprietary NX SulphuRec TM technology for a new SRU. NX SulphuRec TM is a portfolio of proprietary sulphur recovery technologies, based on the integration of modified Claus and tail gas treatment processes, aimed at reducing the environmental impact of acid and sour gases produced during the refining process.

The development and implementation of modern process instruments and control systems in sulphur recovery units has increased significantly over the last decade. In this article, the impact of BTEX on sulphur plant operations and how the BTEX concentrations can be measured are discussed.

Global sulphur prices underwent increases in some key benchmark markets during October, but spot activity nevertheless remained muted, with demand subdued and availability tight. Market participants continue to closely track geopolitical developments.

Metso has appointed Sami Takaluoma the company’s new president and CEO, effective from November 1, 2024. Metso’s outgoing president and CEO, Pekka Vauramo , will continue with the company as per his contract until the end of 2024, to ensure a smooth transition of responsibilities. Sami Takaluoma has been with Metso since 1997 and has led Metso’s Services business area since 2021. He has been a member of Met-so’s Leadership Team since 2017.

Marcus Weber of Fluor discusses degassing units for large scale sulphur recovery units, evaluating the pros and cons of various available commercial technologies with the emphasis on mega size sulphur recovery units and focussing on how technology can lower degassing capex via economy of scale for new facilities or existing facilities undergoing expansion.

Short term supply constraints are dominating acid markets at present, but increasing smelter production across Asia may lead to oversupply in the longer term.

Global sulphur prices are expected to continue rising in certain regions but at a reduced rate of increase. Recent higher spot prices in the Middle East are likely to carry over to other markets. Sulphur affordability in key markets such as China remains good, reinforced by recent increases in phosphate prices.

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.
