  • 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.

  • Oxygen-enhanced Claus carbon dioxide recovery
    Patent number: 11097952
    Abstract: Processes and systems for oxygen-enhanced Claus carbon dioxide recovery are disclosed. Oxygen is fed to a sulfur recovery unit instead of air. The tail gas is fed to a tail gas treatment unit which produces a treated tail gas, and the treated tail gas is processed in a carbon dioxide recovery unit to produce a carbon dioxide product. A method for retrofitting an existing sulfur recovery unit and tail gas treatment unit so as to recover the carbon dioxide product is also disclosed.
