TotalEnergies has signed agreements with Air Liquide to develop two projects in the Netherlands for the production and delivery of some 45,000 t/a of green hydrogen produced using renewable power, generated mostly by the OranjeWind offshore wind farm, developed by TotalEnergies (50%) and RWE (50%). These projects will cut CO2 emissions from TotalEnergies’ refineries in Belgium and the Netherlands by up to 450,000 t/a and contribute to the European renewable energy targets in transport.

Russian media reports suggest that a large scale Ukrainian drone strike on February 3rd attacked a number of oil and gas processing facilities, including Gazprom’s Astrakhan Gas Processing Plant. Video of the site showing fires burning were posted to social media. Astrakhan is one of the largest sulphur producing sites in Russia, with an output of around 3.5 million t/a in 2024. The Moscow Times reported that production had been shut down at the site, and would likely remain so for “several months”.

Rapidly increasing lithium production is projected to require several million t/a of sulphuric acid in the next few years, with China, the USA and Australia the main consumers.

Building on the success of its previous conferences, SulGas Mumbai 2025 brought together 154 sulphur and gas treating stakeholders, representing 68 companies for its 7th technical forum in the Indian subcontinent. We report on some of the key topics on the agenda.

The first installed combination of a regenerative SO2 scrubbing system with a sulphuric acid plant using Worley Chemetics’ CORE™ reactor technology started up in November 2022. The combination of these technologies allows production of high-grade sulphuric acid from gases with low and/or fluctuating SO2 concentrations. C. Trujillo Sanchez and R. Dijkstra of Worley Chemetics report on the design concepts of this integrated process, highlight where it is most effective and report on the start-up and first years of operation of the plant.

ADNOC Gas has appointed Fatema Al Nuaimi as its new Chief Executive Officer, effective January 1st, 2025.

Al Nuaimi, an accomplished industry leader with extensive experience within ADNOC’s gas and energy sectors, is tasked with steering ADNOC Gas’ ambitious growth strategy focused on business expansion, decarbonisation, and future-proofing operations.

Apart from having a good plant design, good maintenance practices and good operational discipline are key to optimise the performance of an acid plant and to protect it from corrosion and achieve a long life. B. Mumba, T. Mwanza and P. Ng’ambi of Kansanshi Mining PLC explore the Kansanshi sulphuric acid plant operations and the key parameters monitored and practices adopted that have helped to extend the catalyst campaigns from two years to four years.

Preventing regenerator amine carryover to the sulphur recovery unit can have catastrophic consequences and must be avoided at all costs. B. Spooner and M. Sheilan of SGS Amine Experts detail how by correctly interpreting operating data, having proper instrumentation and good chemical analysis, amine carryover can be prevented.
