As sulphur recovery units operate at progressively higher temperatures, creep stress in the furnace refractory lining can lead to deformation or even failure of the bricks and require the shutdown of the SRU. UK-based DSF Refractories have developed a product which minimises creep stress damage at high temperatures, for a longer-lived furnace lining.
Sulphur is becoming an increasingly important crop nutrient, due to a combination of lower airborne sulphur emissions, the increasing prevalence of high analysis fertilizers, and higher cropping intensities.
