ABSTRACT:
A process and apparatus for preparing a porous, particulate sulfur by combining a coherent molten sulfur stream with a coherent water stream to provide an aqueous slurry of a porous, particulate sulfur having a uniform particle size distribution. In the process of this invention, a molten sulfur stream is passed through a substantially downwardly oriented, rectangular slot to provide a sheet of molten sulfur, and said sheet of molten sulfur is sheared by directing at least one sheet of water thereat, at a velocity and flow rate sufficient to disrupt said sheet of molten sulfur and provide solid sulfur particles having a substantially uniform size. The solid sulfur particles are recovered, as an aqueous slurry thereof, and separated from said slurry by substantially removing the water therefrom. An apparatus for carrying out the above process includes a novel molten sulfur lift for elevating the molten sulfur to a height sufficient to provide a head pressure of at least 2 feet of sulfur at the downwardly oriented, rectangular slot.
