H2S Recovery from Claus Tail Gas Treatment and Liquid Sulphur

  • Siirtec Nigi’s  Sulphur Degassing Technology can reduce the dissolved H2S concentration of tail gas to less than 10 ppmw.

    Tail Gas Clean Up

    The Claus converters temperature limits the sulphur conversion:

    N° Reactor             Sulphur Recovery

    2                                 94-96﹪

    3                                 96-98﹪

    4                                 97-98.5﹪

    The sulphur recovery can increased to as much as 99.9% through the Claus integration with the tail gas clean up unit.
