An incinerator bums mercury-contaminated waste. The waste material has an ash content of 1%. The solid waste feed rate is 1000 Ib/h and the gas flowrate is 20,000 dscfm. It is reported that the average mercury content in the particulates was 2.42 pg/g when the vapor concentration was 0.3mg/dscm. For the case where incinerator emissions meet the particulate standard of 0.08 gr/dscf (0.1832 g/dscm) with a 99.5% efficient electrostatic precipitator (ESP), calculate ... 

SPM emission can be estimated as much as 1/5-1/3 of the total ash emission from the power plant. In fact, such a situation took place before the year 1995, when units of the old generation were not equipped with high-efficient electrostatic precipitators (ESP). Recently, the situation in the Mae Moh Power Plant associated with SPM pollution has been significantly improved the ESPs together with flue gas desulfurization units have been installed for all units, except of units 1-3 of relatively small capacities (Khummongkol, 1999). However, previous extensive emissions of various pollutants were accompanied with the accumulation of HM in soils and other components of biogeochemical tropical chains.

Emissions of primary ash particles can be controlled efficiently (up to 99.99%) by the combination of an efficient electrostatic precipitator or baghouse and wet FGD system (Tables 22.3 and 22.8). Most of trace metals, except for volatile elements such as mercury and selenium, are captured with the primary particles (Sondreal et al, 2004, 2006 Yang et al., 2007 Wang et al., 2008). 

An adequate treatment of the electrostatic properties of the systems of interest is crucial for the understanding of the dynamic properties of ion channels. We now consider the most common methodologies used to implement accurate and efficient electrostatic force-field schemes. 

Moreover, selectivity could be also enhaneed if a specific interaction between the immobilized catalyst and the substrate in solution were to occur. A significant example is that of the voltam-metric detection of NO in the rat brain from a carbon fiber microelectrode modified with a [(H20)Fe PWii039] -containing poly(N-methylpyrrole) film and a Nation outer layer [150]. The good selectivity of this sensor was attributed not only to the Nafion membrane, which constituted an efficient electrostatic barrier against anionic interferents, but also to the formation of a metal-nitrosyl complex between the heteropolyanion and NO. The in vivo NO measurements were validated by injecting the rat with an NO-synthase inhibitor, which led gradually to the disappearance of the NO oxidation peak (Fig. 7). 

Reduced particulate emissions. To reduce emission of particulates, better cyclones and high-efficiency electrostatic precipitators are being added to FCC units. At delayed coking units, enclosed coke conveyors and storage systems have been installed.
