A review of elemental mercury removal processing

Abstract

Public concern has recently increased over the potential risk of toxic elements emitted from anthropogenic sources. Among these, mercury has drawn special attention owing to its increasing level of bioaccumulation in the environment and in the food chain, with potential risks for human health. This paper presents an overview of research related to mercury control technology and identifies areas requiring additional research and development. It critically reviews measured mercury emissions progress in the development of promising control technologies, including catalytic oxidation, sorbent injection, photochemistry oxidation, and air pollution control devices.

Elemental mercury vapor adsorption of copper-coated porous carbonaceous materials

“…Coal-fired utility boilers have been now identified as the dominant anthropogenic source of mercury. As a result, an attempt to establish a fundamental understanding of the behavior of mercury in coal-fired power plants and to develop a cost-effective method for removing mercury from flue gases has received more attention over the past decade [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

Stability and Performance of Physically Immobilized Ionic Liquids for Mercury Adsorption from a Gas Stream

“…A number of technologies have been used for the removal of Hg 0 , which is substantially more difficult to remove from a gas stream than Hg 2+ . Bae et al (2011) critically reviewed various Hg 0 removal processes with capturing capacity. Recently, ionic liquids (ILs) have shown an ability to remove both Hg 0 and Hg 2+ .…”
