Study of elemental mercury re-emission in a simulated wet scrubber

► In this paper a study is reported on the re-emission of mercury from wet flue gas desulphurization systems. ► A simulated batch reactor was used in the experiments. ► It was found that scrubber temperature and pH, and ionic chemistry affects the re-emission of mercury. ► Four reagents were tested on their ability to mitigate the re-entrainment of mercury. ► These reagents were found successful in helping prevent mercury re-emission.
