  • SULFUR MANAGEMENT METHOD
    Publication number: 20210130719
    Abstract: A method of managing sulfur in a sulfur-containing stream may include steps of providing a sulfur-containing stream; converting sulfur within the sulfur-containing stream to elemental sulfur; transporting the elemental sulfur to a location at or near a sulfur oxide injection location; converting the elemental sulfur to sulfur oxides; recovering electrical energy from said step of converting the elemental sulfur to sulfur oxides; injecting the sulfur oxides into the sulfur oxide injection location. The method may include steps of screening a plurality of injection locations and selecting, from the screened plurality of injection locations, a particular sulfur dioxide injection location with specific reservoir characteristics for the sulfur oxides.

  • Method and apparatus for flue gas treatment
    Patent number: 8728423
    Abstract: A method for flue gas treatment includes branching part of a flue gas stream emitted from a gas turbine from an upstream side or a downstream side of an exhaust heat recovery boiler and subjecting the branched part to combustion with a fuel in an auxiliary boiler so as to increase carbon dioxide concentration in the branched part prior to recombining the flue gas stream from the auxiliary boiler with the remaining part of the flue gas stream from the gas turbine to form a combined flue gas stream having a carbon dioxide concentration for efficient recovery in a carbon dioxide recovery apparatus.
