Sulfur recovery system
An apparatus is described for the recovery of sulfur comprising Claus conversion means for converting hydrogen sulfide to sulfur and for producing an effluent stream comprising hydrogen sulfide, sulfur dioxide, and means for providing in the effluent stream reducing species in at least the stoichiometric amount required for converting 111 sulfur species in the effluent stream to hydrogen sulfide, hydrogenation means in flow communication with the Claus conversion means for receiving the effluent stream therefrom and for converting substantially all sulfur compounds therein and for producing a hydrogenerated effluent stream containing substantially all sulfur compounds as hydrogen sulfide, absorber means in flow communication with the hydrogenation means for receiving the thus hydrogenated effluent stream therefrom and for removing hydrogen sulfide therefrom in the presence of a zinc oxide sorbent and for producing an absorber effluent stream reduced in content of hydrogen sulfide, the absorber means comprising at least a first reactor and a second reactor, each of the first reactor and the second reactor containing the zinc oxide sorbent.
