Methods and systems are provided for converting molten sulfur to powder sulfur by gas cooling of atomized sprays of molten sulfur. Certain embodiments contemplate a vertical tower that allows molten sulfur to produce an atomized spray or mist of molten sulfur descending from the top of the vertical tower. Gas introduced to the bottom of the vertical tower flows upward intimately interfacing with the descending atomized molten sulfur spray. The molten sulfur in the form of an atomized sulfur spray is cooled by the gas to form a sulfur powder. In certain embodiments, the sulfur powder formed is sufficiently small to be suitable for combination with a base fluid for producing a slurry for convenient transport of the sulfur particulates. Advantages of certain embodiments include higher efficiencies, lower cost, and production of much smaller solid sulfur average particulate sizes, which in turn allows for easier sulfur transport. |
