摘要： A process for purifying a light hydrocarbon stream containing H 2 S is disclosed in which the selective catalytic partial oxidation of the H 2 S component is carried out while the hydrocarbon components slip through substantially unconverted. A catalyst that favors the partial oxidation of H 2 S over conversion of the hydrocarbon component of a gaseous H 2 S-light hydrocarbon mixture is employed. Apparatus for selectively cleaning up light hydrocarbon streams containing low concentrations (e.g., less than 25 vol.%), and apparatus for selectively cleaning up light hydrocarbon streams having higher concentrations (e.g., greater than 25 vol.%) of H 2 S are also disclosed.

摘要： The disclosed sulfur recovery system and process avoid some of the operational problems of conventional Claus plants and processes by replacing the reaction burner and furnace tube of a conventional Claus plant with a more efficient short contact time catalytic reactor assembly containing a SPOC™ catalyst that operates efficiently at elevated temperatures. Such Claus plant modification also reduces or avoids the negative effects of hydrocarbons, CO2 and ammonia in Claus sulfur plant feeds, and permits efficient processing of dilute to concentrated H2S feeds. The disclosed modification makes possible the expansion of Claus plant capacity at lower cost.

摘要： Sulfur oxides are removed from an oxygen-containing acid gas (102) in configurations and methods in which oxygen is removed from the acid gas using reducing gases at relatively high temperature. The so treated acid gas is then fed to a direct reduction reactor (130) in which the sulfur species are converted to elemental sulfur (132). Contemplated configurations are particularly effective and economically attractive as they are generally not limited by reaction equilibrium as present in a Claus reaction and do not require solvent and solvent-associated equipment.
摘要翻译：在使用还原性气体在相对较高的温度下从酸性气体中除去氧气的构造和方法中，从含氧酸性气体（102）中除去硫氧化物。然后将如此处理的酸性气体送入直接还原反应器（130），其中硫物质转化为元素硫（132）。考虑到的构型特别有效且经济上具有吸引力，因为它们通常不受克劳斯反应中存在的反应平衡的限制，并且不需要溶剂和溶剂相关设备。

摘要： H 2 S-containing gases, particularly such gases at elevated pressure, are treated to remove H 2 S by reaction in a liquid medium with SO 2 , the SO 2 being present in stoichiometric excess with respect to the H 2 S. The SO 2 is produced by combustion of sulfur, preferably sulfur produced in the reaction between H 2 S and SO 2 , preferably with oxygen. The process produces a treated gas that is substantially free of both H 2 S and SO 2 . An acid-gas absorber/stripper system or other system typically found in such processes to raise or concentrate the H 2 S level in the gas to be treated, is not needed in operations according to the invention.
