摘要： A header design for an efficient single pass enlargement process of sulfur granules having two internal piping structures within an external header conduit for delivering separate molten sulfur liquid streams to different sets of nozzles, wherein a first set of nozzles is subjected to flow streams and pressures uniquely different from a second set of nozzles. A water header design may also include two internal piping structures inside an external pipe casing for delivering water in at least two sets of nozzles, wherein the first set is subjected to flow streams and pressures different from the second set. A method of sulfur seed generation and sulfur granule enlargement for processing sulfur, employing a unique sulfur header design with dual internal piping structures, and possibly utilizing in tandem a water header design having a dual internal piping structure for feeding two sets of nozzles.

摘要： Sulfur (or sulphur) spray nozzles disposed with a tank spray liquid molten sulfur into the cooling liquid in the tank. Solid sulfur seeds are formed in the cooling liquid and settle in the tank. The tank may be a spiral dewaterer tank that has a screw conveyor at the bottom of the tank that moves the seeds to a granulating drum for enlargement into sulfur granules. The tank may also he used to capture and remove sulfur dust from a slurry of sulfur dust and water recycled from the granulating drum. The sulfur dust in the cooling tank may be captured by contact with molten sulfur droplets streaming down the cooling liquid column such that the dust particles become incorporated into the droplet, thereby being converted to seed. The granulating drum may be equipped with two or more sets of segmented lifting flights. The sets of flights may not be in alignment. The flights may be spaced apart from the inside surface of the drum with segmented rib members. The rib members may allow for the movement of sulfur seeds and granules between the nights and the inside surface of the drum as the drum rotates.

摘要： 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.

摘要： A portable apparatus for producing sulphur granules includes a granulator with a rotatable drum having distinct zones for seed generation and product growth. The seed generation zone has an intense water spray pattern for each sulphur spray nozzle with intersecting water sprays to solidify molten sulphur and create seeds. The growth zone has a moderate, non-intersecting water spray pattern to allow sulphur nozzles to coat and grow a curtain of seeds into granules. The granulator's exhaust air is filtered either by a heated cyclone separator to recapture residual sulphur particles and moisture before venting, and/or by a granular air filter which uses the produced granules to filter the granulator's exhaust air. A two piece collar enhances maintenance of the granulator's drive system.

摘要： A method of producing micron sized sulphur granules involving the following described steps. Firstly, heating sulphur until the sulphur becomes molten. Secondly, tempering water and inducing movement of the water at velocity. Thirdly, injecting an unbroken stream of the molten sulphur under pressure into the heated water moving at velocity. An explosive dispersion of the molten sulphur into fine sulphur granules occurs, enhanced by shear forces exerted by the movement of the heated water at velocity. The described method is capable of producing spherical sulphur granules within a broad range of 70 microns to submicron sizes. In the preferred ranges, spherical sulphur granules of less than 10 microns are be obtained.

摘要： A process for the production of granular sulfur in a rotating drum in which molten sulfur at a temperature within the range of about 110.degree. to 160.degree. C. is sprayed in a contact zone onto a bed of moving sulfur particles and a continuous curtain of said particles and resulting particles are passed to a cooling zone prior to discharge. A countercurrent flow of substantially inert cooling gas at a temperature in the range of about 10.degree. to 50.degree. C. and containing not more than 8% by volume oxygen is introduced to the cooling zone and a portion or all of said cooling gas is passed through the contact zone. The contact and cooling zones can be formed in a single rotating drum and separated from each other by a retaining ring or formed in separate vessels.Discharge particles from the cooling zone are separated according to size and undersized particles are recycled as fines to the contact zone at a ratio of 4:1 to 2:1 of fines to product granules.

摘要： The invention is a method for freezing liquid sulfur. The method comprises introducing liquid sulfur into a tumbling bed of particulate sulfur to coat the particulate sulfur with liquid sulfur and providing a sufficient amount of water to the tumbling bed of particulate sulfur to maintain the bed temperature below the freezing point of the liquid sulfur.By controlling the temperature of the tumbling bed, particulate sulfur containing only small amounts of moisture can be produced. The product is roughly spherical, free flowing and substantially dust free.
