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.
While sulphuric acid production is dominated by sulphur burning or metallurgical acid routes, pyrite roasting remains a niche sector, particularly in China.
Smelter outages and tight concentrate markets ease an oversupplied market.
While north Africa’s sulphur demand is dominated by its phosphate industry, south of the Sahara it is copper, cobalt and uranium mining, leaching and smelting that hold sway over acid production and demand.
Sulphur prices advanced further in October, more than expected, supported by the supply towards the end of summer becoming restricted, with a number of non-mainstream sources facing logistical constraints.
