<p>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.</p> |
