The most popular method for mercury removal is powdered activated carbon injection (PAC) into flue gases. However, it is recognized that the PAC has some drawbacks such as high cost, narrow working temperature window, and releasing mercury into soil. The objective of this study is to investigate characteristics of mercury oxidation by ozone injection generated by atmospheric pulsed plasma and its water-solubility in a wet scrubber. Hg_0, NO (nitric oxide), and Hg_0+NO gas mixture were used as simulation gas. Above 95% Hg_0 and NO removal was attained by ozone injection.
