ABSTRACT:
A process for producing solid, irregular shaped sulfur nuggets from molten sulfur. The process includes the steps of: gravity flowing molten sulfur at a temperature preferably in the range of about 240.degree.-270.degree. F. to a distributor head positioned closely above or below the surface of a cooling liquid; discharging the molten sulfur from the distributor head in ribbon-shaped streams into a cooling liquid, preferably water, having a temperature in the range of about 170.degree.-190.degree. F.; passing the molten sulfur streams through the cooling liquid until the streams are subdivided and thereafter solidified into nuggets of irregular shape and size; and removing the solid sulfur nuggets from the cooling liquid. The apparatus in which the process is carried out includes a feed system having temperature control apparatus for maintaining the sulfur in a molten state, a reservoir tank for the cooling liquid, a distributor head having elongated discharge slots for flowing the molten sulfur in ribbon-shaped streams into the cooling liquid, and apparatus such as a conveyor belt in the reservoir tank under the distributor head for collecting and removing the solid sulfur nuggets from the cooling liquid.
