Abstract: Apparatus for melting sulphur, including an upstanding tube, or tubes, each being adapted to receive solid sulphur in its top open end and each having a heating jacket therearound. The sulphur along the tube wall is melted and caused to flow along the wall surface and out of the lower end of the tube. A heated plate is spaced from the lower end of the tube whereby flow of the melted sulphur from the tube is permitted, additional sulphur being melted by the plate, and flow of solid sulphur is stopped. The plate is sloped to permit the flow of the liquid sulphur into a trough for flow for storage or use elsewhere.A method of melting sulphur by which solid sulphur is fed into the upper end of a vertical tube. The tube is heated to melt the sulphur against the tube wall. A film of melted sulphur is caused to flow down the wall and out of the tube bottom onto a sloping, heated plate and into a trough for removal or use. The flow of solid sulphur is stopped by the plate.

Abstract: Solid sulfur pellets are prepared from molten sulfur using a gun and pelletizing chamber. Sulfur is ejected from a gun in a form of a thin sheet and dispersed and solidified into solid pellets with a water jet. The pellets and water are separated.
