    Abstract: A dispersion of up to about 70 weight percent elemental sulfur in an aqueous ammonia solution of at least one metal compound selected from the group consisting of soluble zinc and magnesium compounds has reduced corrosive activity toward ferrous metal. The atomic ratio of zinc and/or magnesium to sulfur is from about 0.0002 to about 0.1 and the mole ratio of ammonia to metal compound is from about 0.1 to about 200.

    Abstract: A process for the production of granular sulfur in a rotating drum in which molten sulfur at a temperature within the range of about 110.degree. to 160.degree. C. is sprayed in a contact zone onto a bed of moving sulfur particles and a continuous curtain of said particles and resulting particles are passed to a cooling zone prior to discharge. A countercurrent flow of substantially inert cooling gas at a temperature in the range of about 10.degree. to 50.degree. C. and containing not more than 8% by volume oxygen is introduced to the cooling zone and a portion or all of said cooling gas is passed through the contact zone. The contact and cooling zones can be formed in a single rotating drum and separated from each other by a retaining ring or formed in separate vessels.Discharge particles from the cooling zone are separated according to size and undersized particles are recycled as fines to the contact zone at a ratio of 4:1 to 2:1 of fines to product granules.

    Abstract: Crystalline sulfur particles of predetermined, controlled, relative attrition resistance having diameters less than about 0.5 inch are formed by shock-crystallizing fused sulfur in an agitated quench medium by controlling the fused sulfur temperature at a predetermined level about 238.degree. F. and below 340.degree. F. correlated with the relative particle hardness desired, and controlling the sulfur-quench temperature gradient at a level of at least about 100.degree. F. Crystalline particles having higher relative attrition resistance are obtained at higher fused sulfur temperatures and higher quenching temperature gradients.

    Abstract: The present invention relates to a method of transporting sulfur by pipeline with a minimum of sulfur precipitation and adherence to the internal parts of the pipeline system. By the present invention, the sulfur to be transported is formed into prills thereby reducing the static electricity charge accumulation capacity of the sulfur. The prills of sulfur are then formed into a pumpable slurry in a carrier liquid and the slurry is pumped through the pipeline.
