摘要： A compact sulfur recovery system is disclosed which includes an upflow orientation for the gases through a primary structure including a catalytic partial oxidation reaction zone, a first temperature-control zone, a first Claus catalytic reaction zone, a second temperature-control zone, a first liquid sulfur outlet, and a first effluent gas outlet. The upward flow of the gases puts the hottest gases in contact with the tubes and tube sheet in the waste heat boiler where there is greater confidence in having liquid water in most continuous therewith. In some embodiments, a secondary structure follows the primary structure and comprises a second Claus catalytic reaction zone, a third temperature-control zone, a second liquid sulfur outlet, and a second effluent gas outlet. One or more components of the system employ heat transfer enhancement material in the temperature-control zones, and one or more components deter accumulation of liquid sulfur in the Claus catalytic reaction zones. A process for recovering elemental sulfur from hydrogen sulfide-containing gas streams comprises regulating the temperature of certain components to favor the partial oxidation reaction, and the Claus reaction, as appropriate, and deters pooling of liquid sulfur on the Claus catalyst(s).

摘要： A process and system for producing synthesis gas by a SPOC® enhanced catalytic partial oxidation process is disclosed. Light hydrocarbons in a H2S-containing feed gas are partially oxidized to produce hydrogen and carbon monoxide over a catalyst that simultaneously oxidizes the H2S to produce elemental sulfur. A reaction in which H2S is partially oxidized to elemental sulfur and water takes place instead of a secondary reaction in which a portion of the light hydrocarbon feed is combusted to form CO2 and water. An increase in yield and selectivity for CO and H2 products results, and readily recoverable elemental sulfur is also produced.
