摘要： Disclosed is a method in which hydrogen sulfide-containing liquid sulfur is introduced into a containment vessel to partially fill the containment vessel and create a hydrogen sulfide-containing liquid sulfur phase and a hydrogen sulfide-containing vapor phase. A portion of the hydrogen sulfide-containing liquid sulfur phase is then treated to produce a liquid sulfur-containing phase and a gaseous hydrogen sulfide-containing phase, such that the gaseous hydrogen sulfide-containing phase has a pressure of at least about 60 psig. A portion of the hydrogen sulfide-containing vapor phase is then withdrawn from the containment vessel using at least one eductor driven by a motive fluid, where the motive fluid is the gaseous hydrogen sulfide-containing phase from the container vessel. The hydrogen sulfide-containing waste gas stream exiting the eductor is then treated to reduce the hydrogen-sulfide content of the waste gas.

摘要： A method for removing hydrogen sulfide from liquid sulfur, comprising introducing liquid sulfur containing hydrogen sulfide in an upstream portion of a conduit. The conduit has a fluid outlet in a downstream portion thereof located within a lower portion of a first vessel. The method further includes causing the liquid sulfur to flow through the conduit outlet into the first vessel, up an annulus formed between the conduit and the first vessel and overflow through an outlet positioned at an upper portion of the first vessel into a second vessel which is connected to a liquid sulfur pit operating at atmospheric pressure. Air is introduced into the liquid sulfur located in the annulus at a point between the conduit outlet and said first vessel outlet. The flows concurrently to the direction of flow of the liquid sulfur in the annulus and out of the first vessel outlet into the second vessel thereby removing hydrogen sulfide from the liquid sulfur in the annulus.

摘要： A procedure for the production of polymeric sulfur with improved stability that comprises the stages of: (a) cooling in a vessel for rapid cooling the sulfur vapor from the vaporization of molten sulfur, by bringing it into direct contact with a refrigerating suspension composed of carbon disulphide, soluble sulfur and polymeric sulfur, to a temperature such that part of the sulfur vapor is transformed into a powder-like polymeric sulfur, insoluble in carbon disulphide. (b) extracting the resulting suspension from the cooling vessel; (c) recycling part of said suspension to the vessel for cooling; and (d) sending the rest of the suspension to a maturation stage to stabilize the polymeric sulfur.

摘要： A sulfur purification process is provided. Ash-containing molten sulfur is fed to a centrifuge and subjected to centrifugation under controlled conditions at G forces at least about 4,000 times that of gravity. The centrifugation generates a purified sulfur product and a high-solids sulfur waste stream. A solid bowl disc centrifuge provided with conical discs is used to effect the centrifugal separation of solids from liquids at G forces of at least about 4,000. The centrifuge and related piping system are equipped with heating means so as to maintain the temperature of the sulfur above about 250° F. If large volumes of sulfur are to be treated, e.g., 40 or more long tons per hour, a pretreatment step, where the molten sulfur is first subjected to centrifugation at G forces at least about 4,000 times that of gravity in one or more nozzle bowl centrifuges, is added in order to obtain satisfactory results. In another aspect of the sulfur purification process, the nozzle bowl centrifuge underflow waste stream is further processed in a cyclone-thickener arrangement to obtain a high-solids sulfur waste stream and a moderate-solids sulfur stream which is then mixed with the low-solids sulfur product stream from the nozzle bowl centrifuge(s), or recycled to the feed of the nozzle bowl centrifuge(s).
