  • Patent number: 10131542
    Abstract: Embodiments of the invention include a method for degassing liquid sulphur in a container, a first area of the container being flooded with liquid sulphur and a second area of the container being flooded with a gas, and a gas flow being injected into the first area, wherein liquid sulphur is sprayed into the second area. Embodiments of the invention include a device for degassing liquid sulphur having a container comprising two adjacent areas, the first area being flooded with liquid sulphur and the second area being flooded with gas, and having at least one device for injecting a gas flow into the first area, characterized by a device for spraying liquid sulphur opening into the second area. Other embodiments are also included herein.

  • Patent number: 9994452
    Abstract: The invention relates to a method for treating a hydrocarbon feed gas stream containing CO2 and H2S to recover a purified CO2 gas stream (vii), comprising: a. Separating said feed gas stream into a sweetened gas stream (i), and an acid gas stream (ii); b. Introducing stream (ii) into a Claus unit wherein an oxygen-rich stream is used as a combustive agent in the Claus furnace, thereby recovering a liquid stream of elemental sulfur (iii) and a tail gas stream (iv); c. Introducing the stream (iv) into a Tail Gas Treatment Unit (TGTU) thereby separating said tail gas stream into a CO2 enriched gas stream (v), and a stream enriched in sulfur compounds (vi); d. Compressing stream (v) exiting the TGTU; e. Passing the compressed CO2 enriched gas through a CO2 purification unit thereby recovering a purified CO2 gas stream (vii), and the device for carrying out said method.

  • Patent number: 8431105
    Abstract: With a method configured to generate process gas that contains hydrogen sulfide and sulfur dioxide for the Claus process, hydrogen-sulfide containing feed gas is burned with pure oxygen by means of several burners opening out into a combustion chamber wherein the pure oxygen is fed into the combustion chamber through a central tube each, the feed gas through a tube arranged coaxially around the central tube and inert gas as purge gas via an annular duct coaxially surrounding the feed gas tube. A favorable option of the method consists in the use of CO2 reclaimed by desorption of laden methanol as purge gas.

  • Publication number: 20080311030
    Abstract: In an apparatus for continuously recovering sulfur from a gas stream containing 0.1 to 3.0 vol-% H2S, further gaseous sulfur compounds and sulfur, the gas stream first is passed over a reduction stage consisting of hydrogenation catalyst and then over a selective oxidation stage consisting of oxidation catalyst. To reduce the amount of apparatus involved, it is provided to arrange the reduction stage and the selective oxidation stage in a reaction tank and to leave a space for introducing a gaseous cooling medium into the gas stream between the two stages.

  • Patent number: 5149509
    Abstract: The apparatus comprises a container which has a central cooling chamber and an annular chamber which surrounds the cooling chamber and contains catalyst. The gas mixture to be reacted contains H.sub.2 S and SO.sub.2 enters the annular chamber and first flows through the catalyst. The cooling chamber contains at least one coolant line and is provided with a passage for gas mixture coming from the annular chamber and with a gas outlet. The cooling chamber is provided at its bottom end with a drain for the liquid elementary sulfur .
