Decrease in Friability of Elemental Sulphur and Control of Acidity Development in Sulphur Cargos

The two major problems in handling, transportation and storage of sulphur, are dust emission and acidification. Retention of polymeric content of sulphur, Sx, results in a considerable increase in the mechanical strength of solid sulphur and decrease in friability. It is well known that naturally occurring bacteria thiobacilli oxidants, attack stockpiled sulphur or any area which stores or handles elemental sulphur and cause acidification. Treatment of sulphur with a biocide or antibacterial agent can prevent acidity development in sulphur. A new efficient method has been devised based on the use of inorganic salts.
