Abstract
Sulfur seeds may be produced by spraying liquid molten sulfur from a sulfur spray nozzle into a moving stream of liquid. Some of the sulfur may pass through the liquid and some of the sulfur may be entrained in and transported by the stream of liquid, or all of the sulfur may be entrained in the stream of liquid. The sulfur droplets that are entrained in the stream of liquid may be carried by the liquid to a cooling tank, which may be a spiral dewaterer tank with an angled bottom and a screw conveyor. An opening may be made in the bottom surface of the screw conveyor housing of the spiral dewaterer tank for liquid to drain from the screw conveyor as it moves sulfur seeds from the tank to a the drum. A screen may be disposed across the opening, and a drain trough attached to the screw conveyor housing to capture any liquid and solids that move through the screen. A wash line may assist in moving solids that pass through the screen.
