The switch towards battery technologies like lithium iron phosphate (LFP) is leading to major growth in demand for sulphur and sulphuric acid.

Süd-Chemie discusses the importance of pressure drop in a sulphuric acid plant and the many benefits that can be gained from using a guard bed, typically in the first bed of the converter to safeguard the catalyst bed and increase campaign life.

Thiomaterials reports on the key features and successful performance of Thiotrack sulphur concrete sleepers, offering high fatigue endurance with a truly reversible circular binder.

Bryan Research & Engineering (BR&E) and INEOS GAS/SPEC continue their review of neutralisation of heat stable salts. Part 2 focuses on how caustic (NaOH) affects amine chemistry and corrosion and the effects of adding too much NaOH.

Begg Cousland Envirotec reviews different mist eliminator types and some of the operational problems encountered which can be managed by correct installation, targeted cleaning or replacement, and selecting appropriate corrosion-resistant materials.

In this real world case study, Topsoe demonstrates how cost effective catalyst changes can result in significant production increase without any equipment changes or revamps, all while maintaining compliance with emission limits.

Recalibrate™ has developed a next generation sulphur burning plant to produce sulphuric acid with ultra-low sulphur dioxide and zero NOx emissions, designed to derisk the permitting process and increase speed to market for new sulphuric acid plants.

The Sulphur Institute celebrates its 65th anniversary this year. In this article the organisation describes its lasting legacy and global impact.

Joel Cantrell of Bryan Research & Engineering and Clay Jones of INEOS GAS/SPEC re-evaluate the historical practice of intentionally adding strong base such as caustic (NaOH) to amine with the purpose of improving performance and reducing corrosion by “neutralising” heat stable amine salts (HSAS) which have accumulated in the amine.

Platinum-promoted honeycomb catalyst bricks offer function as total oxidation catalysts that convert all oxidisable species under appropriate temperature and oxygen conditions. P&P Industries presents a case for a H2S-rich gas stream – relevant to the fibre industry, Claus offgas treatment, and other chemical sectors.
