Equipment available for this kind of testwork includes:
2, 10 and 18.75 L electrically heated pressure autoclaves
Titanium and stainless steel reactor inserts
High pressure reagent injection systems
Data logging capability (18.75 L autoclave only)
Blast room containment
For pressure oxidation in particular, hrltesting enjoys unrivalled expertise in the area of chemical analyses for sulphur species (elemental sulphur, sulphide and sulphate).
