Device, useful for continuous recovery of sulfur from hydrogen sulfide comprises reducing sulfur to hydrogen sulfide and oxidizing the hydrogen sulfide to sulfur

摘要

Device for the continuous recovery of sulfur from 0.1-3 vol.%, preferably 0.5-1.5 vol.% of hydrogen sulfide and other gaseous sulfur compound e.g. sulfur dioxide comprises reducing a sulfur to hydrogen sulfide by pouring a hydrogenated catalyst and the gaseous sulfur over a solid bed zone, oxidizing the hydrogen sulfide to sulfur by pouring a oxidation catalyst over the solid bed zone, where in a reaction container (4), a first segment of the solid bed zone (5) is formed from the hydrogenated catalyst and a second segment of solid bed zone (6) is formed from oxidation catalyst. Device for the continuous recovery of sulfur from 0.1-3 vol.%, preferably 0.5-1.5 vol.% of hydrogen sulfide and other gaseous sulfur compound such as sulfur dioxide, carbonyl sulfide and carbon disulfide and sulfur containing gas streams, comprises reducing a sulfur to hydrogen sulfide by pouring a hydrogenated catalyst and the gaseous sulfur over a solid bed zone, oxidizing the hydrogen sulfide to sulfur by pouring a oxidation catalyst over the solid bed zone, where in a reaction container (4), a first segment of the solid bed zone (5) formed from the hydrogenated catalyst, which is arranged in a gas flow direction and a second segment of the solid bed zone (6) formed from the oxidation catalyst, which is arranged in a gas flow direction and a space (7) exists between the solid bed zones for introducing a gaseous optionally atmospheric oxygen containing cool medium in the gas stream. An independent claim is included for the continuous recovery of sulfur, where the gas flow is initiated at 160-280[deg]C, preferably 180-240[deg]C.
