Abstract: The present disclosure is directed to an additive mixture and method for controlling nitrogen oxide(s) by adding the additive mixture to a feed material prior to combustion.

Abstract: The disclosure provides an improved means of controlling mercury emissions from coal-fired boiler applications. Specifically, the disclosure comprises a static mixing device placed in the flue gas stream. The static mixing device can enhance dispersion of injected sorbents in the flue gas, resulting in improved mercury capture at a lower sorbent injection rate.

Abstract: The present disclose is directed to a method for controlling iodine levels in wet scrubbers, and, in particular, recirculating wet scrubbers.

Abstract: The present disclosure is directed to a fluidized bed contaminant treatment system comprising plural stacked distributor elements that can be rigidly fixed to a housing surrounding the fluidized bed.

Abstract: The present disclosure is directed to the use of elemental or speciated iodine and bromine to control total mercury emissions.

Abstract: The present disclosure is directed to the use of elemental or speciated iodine and bromine to control total mercury emissions.

Abstract: The present disclosure is directed to a dense-phase additive transportation system for additive injection into a contaminated gas stream.

Abstract: The present invention is directed to an additive, primarily for low sulfur and high alkali coals, that includes a transition metal and optionally a halogen to effect mercury oxidation.

Abstract: The present disclosure is directed to the use of elemental or speciated iodine to control total mercury emissions.

Abstract: The present disclosure is directed to the introduction of an additive to a contaminated gas stream. An additive introduction system uses a compressor and carbon dioxide separator to provide a treated carrier gas for introduction of an alkaline additive to a contaminated gas stream.

Abstract: A flue gas additive is provided that includes both a nitrogenous component to reduce gas phase nitrogen oxides and a halogen-containing component to oxidize gas phase elemental mercury.

Abstract: The present invention is directed to an additive, primarily for combustion of low sulfur and high alkali coals, that includes a transition metal to impact positively bottom ash slag and optionally a halogen to effect mercury oxidation and collection in the flue gas.

Abstract: The present disclosure is directed to a process that allows dry sorbents to remove a target constituent, such as carbon dioxide (CO2), from a gas stream. A staged fluidized bed separator enables gas and sorbent to move in opposite directions. The sorbent is loaded with target constituent in the separator. It is then transferred to a regenerator where the target constituent is stripped. The temperature of the separator and regenerator are controlled. After it is removed from the regenerator, the sorbent is then transferred back to the separator.

Abstract: The present disclosure is directed to the application of additives to a feed material at a location remote from an industrial facility using the feed material.
