Mechanisms of Mercury Capture and Breakthrough on Activated Carbon Sorbents
An extensive series of studies was performed at the Energy & Environmental Research Center with mercury (Hgo) sorbents in a thin bed using combinations of various flue gas constituents. This work determined that all the sorbents exhibited breakthrough in about I hour in the full flue gas mixture, and the mercury emitted after breakthrough is an oxidized mercury species. Trapping of the oxidized...
متن کاملImpact of sulfur oxides on mercury capture by activated carbon.
Recent field tests of mercury removal with activated carbon injection (ACI) have revealed that mercury capture is limited in flue gases containing high concentrations of sulfur oxides (SOx). In order to gain a more complete understanding of the impact of SOx on ACl, mercury capture was tested under varying conditions of SO2 and SO3 concentrations using a packed bed reactor and simulated flue ga...
متن کاملMercury Binding on Activated Carbon
Density functional theory has been employed for the modeling of activated carbon using a fused-benzene ring cluster approach. Oxygen functional groups have been investigated for their promotion of effective elemental mercury binding on activated carbon surface sites. Lactone and carbonyl functional groups yield the highest mercury binding energies. Further, the addition of halogen atoms have be...
متن کاملModeling Mercury Control with Powdered Activated Carbon
Fulland pilot-scale data has been collected on the effectiveness of powdered activated carbon (PAC) injection for control of mercury emissions from flue gas of coal-fired power plants. However, there has been limited modeling work accounting for the removal of mercury by existing equipment as shown by Information Collection Request (ICR) data and by PAC injection, independently of one another. ...
متن کاملElemental Mercury Spills
Sources of elemental mercury (Hg0) include old natural gas regulators, manometers, sphygmomanometers, thermometers, and thermostats. Causes of Hg0 spills include improper storage, container breakage, children playing with Hg0, the breakage of devices containing Hg0, and ritualistic use of Hg0. Inhalation is the primary exposure route for Hg0. Mercury released into the environment can enter lake...
