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： A process for purifying a light hydrocarbon stream containing H2S is disclosed in which the selective catalytic partial oxidation of the H2S component is carried out while the hydrocarbon components slip through substantially unconverted. A catalyst that favors the partial oxidation of H2S over conversion of the hydrocarbon component of a gaseous H2S-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 H2S are also disclosed.

摘要： A process for removing sulfur from a H2S-containing gas stream is disclosed. A preferred embodiment of the process comprises incorporating a short contact time catalytic partial oxidation reactor, a cooling zone, and a condenser into a conventional refinery or gas plant process, such as a natural gas desulfurizer, a hydrotreater, coker or fluid catalytic cracker, in which sulfur removal is needed in order to produce a more desirable product. An H2S-containing gas stream is fed into a short contact time reactor where the H2S is partially oxidized over a suitable catalyst in the presence of O2 to elemental sulfur and water.

摘要： An apparatus and process for recovering elemental sulfur from a H2S-containing waste gas stream are disclosed, along with a method of making a preferred catalyst for catalyzing the process. The apparatus preferably comprises a short contact time catalytic partial oxidation reactor, a cooling zone, and a sulfur condenser. According to a preferred embodiment of the process, a mixture of H2S and O2 contacts the catalyst very briefly (i.e, less than about 200 milliseconds). Some preferred catalyst devices comprise a reduced metal such as Pt, Rh, or Pt—Rh, and a lanthanide metal oxide, or a pre-carbided form of the metal. The preferred apparatus and process are capable of operating at superatmospheric pressure and improve the efficiency of converting H2S to sulfur, which will reduce the cost and complexity of construction and operation of a sulfur recovery plant used for waste gas cleanup.
