    摘要: A liquid separator system having a gas phase zone, an aqueous phase zone and a denser liquid zone is used to separate mixtures of fluids. The separator can be used for separating molten sulfur from liquid redox solution or reslurry water. The system includes a vessel with a top part and a bottom part. The vessel has a larger diameter at the top part than at the bottom part. The system also includes an inlet for introducing a redox solution or reslurry water and molten sulfur, which is denser than redox solution or reslurry water, into the vessel. An outlet near the bottom part of the vessel allows a flow of the molten sulfur from the vessel. An interface control structure senses an interface level between the redox solution or reslurry water and the molten sulfur, and the interface control structure controls the flow of molten sulfur from the outlet. The interface control structure is adjusted to optimally alter the vertical height of the interface level within the vessel so that the residence time of the molten sulfur in the vessel does not decrease as the sulfur production throughput decreases, and so that the interface area of the molten sulfur and the redox solution is reduced as the sulfur throughput decreases. A pressure controller monitors the pressure in the vessel and adds or removes gas from a gas phase zone in the vessel to maintain a predetermined pressure regardless of the vertical height of the interface.

    摘要: A process and an apparatus are described for treatment of a gas containing hydrogen sulphide and sulphur dioxide, for example a Claus plant tail gas, in which the gas is brought into contact with an organic solvent (1) e.g. polyethylene glycol 400, containing a catalyst e.g. sodium salicylate, in at least one gas-liquid reactor-contactor (2) and a gas (20) substantially no longer containing hydrogen sulphide and sulphur dioxide is recovered. A single-phase solution (4) of solvent and sulphur is extracted from the reactor-contactor and a portion is cooled in at least one cooling zone (8) to obtain a suspension of sulphur crystals in the solvent, the crystallised sulphur is separated from the solvent in a separation zone (10), the sulphur-depleted solvent (14, 15) is recovered and recycled at least in part to the reactor-contactor (2), and the sulphur (13) is recovered.

    摘要: A foul gas containing H.sub.2 S is brought into the presence of SO.sub.2 in a first stage to permit the reaction between SO.sub.2 and H.sub.2 S to form water and elemental sulfur. The SO.sub.2 is solubilized in an absorbent composition which includes a solvent for both SO.sub.2 and H.sub.2 S so that the H.sub.2 S in the foul gas is first solubilized in the absorbent composition where it is then brought into contact with the solubilized SO.sub.2 for reaction between a major portion of the H.sub.2 S and the solubilized SO.sub.2 to form elemental sulfur. The gas is then passed to a second stage where any remaining H.sub.2 S is removed by aqueous catalytic reaction of the type conventional in the prior art. The apparatus utilized to carry out the present invention preferably includes a two stage column in which the first stage provides the absorbent material containing solubilized SO.sub.2 for reaction with the H.sub.2 S of the foul gas. During the SO.sub.2 extraction stage the major portion of the H.sub.2 S is removed from the foul gas. The gas is then conveyed from the first stage to a second stage which comprises a conventional aqueous catalytic scrubbing operation where the remainder of the H.sub.2 S is removed. The absorbent composition utilized in the process comprises solvents that dissolve SO.sub.2 and/or H.sub.2 S which can be heated to a temperature above the melting point of sulfur without detrimentally affecting the solvent so that it may be recycled through the system.

    摘要: A suspension of sulfur in a scrubbing liquid is preheated with steam to a temperature above the melting point of the sulfur so that the latter spontaneously melts in the suspension which is introduced into a separating chamber in a sealed vessel. The scrubbing liquid is decanted over a weir into a second chamber while the molten sulfur is drawn out at the bottom into a third chamber. The separating chamber is maintained at a pressure and temperature, by a vapor cushion above the liquid, such that evaporation of the incoming liquid does not occur, i.e. the separation pressure is the saturation pressure of the cushion. To prevent vapor condensation on the molten sulfur, the latter is maintained at a temperature higher than that of the liquid in the adjacent separating chamber.

    摘要: High quality hydrophilic sulfur is recovered from a biologial conversion zone in which a sulfur containing compound such as a sulfide is converted to elemental sulfur. The sulfur is rendered hydrophilic due to the fine particle size and attachment of biomass to the particles. The sulfur is recovered as an undamaged agglomerate powder after being processed in at least two stages of purification.

    摘要: There is disclosed a process for the removal of sulfur from an aqueous sulfur-containing suspension through sulfur coalescence. Sulfur coalescence is initiated by passing the aqueous sulfur-containing suspension through a multi-passage filtering media. In one embodiment of the present invention, the aqueous sulfur-containing suspension is passed through a filtering media comprised of randomly oriented fibrous filter material. In another embodiment of the present invention, the aqueous sulfur containing suspension is passed through sintered metal filters. Optionally, downstream polishing, or filtration, steps using either the above enumerated filters or combinations of the above filters can also be used.
