  • Method to reduce mercury, acid gas, and particulate emissions
    Patent number: 10589292
    Abstract: A waste gas is contacted with a mercury removal agent to remove mercury and a flue gas conditioning agent to alter a resistivity and/or cohesivity of particulates. The flue gas conditioning agent can be substantially free of SO3 and/or comprise more than about 25 wt. % SO3, and/or the mercury removal agent can be substantially unaffected by the flue gas conditioning agent. An amount of mercury removed from the waste gas in the presence of the flue gas conditioning agent can be the same or more than that removed from the waste gas in the absence of the flue gas conditioning agent. An amount of the acid gas removed, by an acid gas removal agent, from the waste gas in the presence of the flue gas conditioning agent can be the same or more than that removed from the waste gas in the absence of the flue gas conditioning agent.

    Publication number: 20150050202
    Abstract: A method is provided in which a contaminated waste gas, comprising particulates, an acid gas, and mercury, is contacted with a mercury removal agent to remove or cause the removal of mercury from the waste gas and a flue gas conditioning agent to alter at least one of a resistivity and cohesivity of the particulates. At least one of the following statements is true: the flue gas conditioning agent is substantially free of SO3, an amount of mercury removed from the waste gas in the presence of the flue gas conditioning agent is at least the same as an amount of mercury removed from the waste gas in the absence of the flue gas conditioning agent; the flue gas conditioning agent comprises more than about 25 wt.
