  • Hydrogen sulfide removal from anaerobic treatment
    Patent number: 9764966
    Abstract: Hydrogen sulfide can be removed from a liquid effluent of an anaerobic reactor, by subsequently: —contacting the effluent liquid in counter current with a treated product gas of the anaerobic reactor to absorb hydrogen sulfide in the gas, —collecting the desulfurized effluent liquid after said contacting, —discharging at least part of the collected desulfurized effluent recirculation liquid as a treated effluent. To a remaining part of the desulfurized effluent waste water can be added and mixed, and the mixed water can be fed to the anaerobic reactor. Spent gas of the contacting step can be combined with sulfide-containing product gas of the anaerobic reactor and treated by desulfurization.
    Type: Grant
    Filed: December 20, 2013
    Date of Patent: September 19, 2017
    Assignee: Paques I.P. B.V.

  • HYDROGEN SULFIDE REMOVAL FROM ANAEROBIC TREATMENT
    Publication number: 20150344326
    Abstract: Hydrogen sulfide can be removed from a liquid effluent of an anaerobic reactor, by subsequently: —contacting the effluent liquid in counter current with a treated product gas of the anaerobic reactor to absorb hydrogen sulfide in the gas, —collecting the desulfurised effluent liquid after said contacting, —discharging at least part of the collected desulfurised effluent recirculation liquid as a treated effluent. To a remaining part of the desulfurised effluent waste water can be added and mixed, and the mixed water can be fed to the anaerobic reactor. Spent gas of the contacting step can be combined with sulfide-containing product gas of the anaerobic reactor and treated by desulfurisation.
