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.
