发明名称 METHOD TO REDUCE MERCURY, ACID GAS, AND PARTICULATE EMISSIONS
摘要 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 SO3and/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.

主权项 1. A method, comprising: receiving a contaminated waste gas comprising particulates, an acid gas, and mercury; contacting the waste gas 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; and removing at least most of the mercury and particulates from the waste gas to produce a treated gas, wherein at least one of the following is true: (i) the flue gas conditioning agent is substantially free of SO3, wherein 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; (ii) the flue gas conditioning agent comprises more than about 25 wt. % SO3 and the mercury removal agent is substantially unaffected by the flue gas conditioning agent, wherein 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; and (iii) wherein the waste gas is contacted with an acid gas removal agent to remove or cause the removal of the acid gas from the waste gas and wherein an amount of the acid gas removed from the waste gas in the presence of the flue gas conditioning agent is at least the same as an amount of the acid gas removed from the waste gas in the absence of the flue gas conditioning agent.
