  • REACTOR SYSTEM AND METHOD THEREOF FOR DEGASSING SULFUR
    Publication number: 20230416087
    Abstract: A reactor system can include a reactor, including: a first inlet for a first stream including a liquid sulfur including a dissolved hydrogen sulfide, a polysulfide, or a combination thereof. A second inlet can be for a second stream, wherein the second stream can be an oxygen-containing gas with no more than about 2%, by weight nitrogen. A packing can be in contact with a catalyst.

  • LIQUID SULFUR DEGASSING
    Publication number: 20230339751
    Abstract: A method and system for liquid sulfur degassing is disclosed. The method and system generally involve degassing liquid sulfur in a degassing vessel, and the level of the liquid sulfur in the degassing vessel is controlled in the degassing vessel by determining the level of liquid sulfur in the degassing vessel.

  • Systems and methods for degassing of sulfur
    Patent number: 11034583
    Abstract: Contemplated systems and methods for removing polysulfides and hydrogen sulfide from liquid sulfur of a Claus plant include (a) physically separated steps of catalytic decomposition of polysulfides and gas stripping, or (b) use of the stripping gas as the continuous phase in a packed column with decomposition catalyst to so avoid catalyst attrition.
