Maire Group says that its NextChem (Sustainable Technology Solutions) subsidiary has been awarded a three-year contract by Saudi Aramco Total Refining and Petrochemical (SATORP) – a joint venture between Saudi Aramco and TotalEnergies – to provide engineering and technology services related to the sulphur recovery complex of SATORP’s refinery in Jubail, Saudi Arabia. NextChem will provide process and engineering advisory services to enhance performance, support operational troubleshooting, and improve energy efficiency and the carbon footprint of the three units (sulphur recovery unit, amine regeneration unit and sour water stripper) which comprise the sulphur recovery complex. The services will also include recommendations for capital investment opportunities, design enhancements, and technology improvements.

Metso has launched its new Cu POX leaching process for the copper extraction industry. The company says that, as ore compositions change due to depletion of deposits and increasing environmental and efficiency demands, this solution not only maximises copper recovery but also reduces environmental impact.

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.

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.
