The report presents a demonstration of mercury air emission reduction at a coal-fired power plant in Russia. A wet particulate matter (PM) scrubber installed in Toliatti thermal plant has been modified to allow for addition of chemical reagents (oxidants) into the closed-loop liquid spray system. The addition of oxidant resulted in significant improvement of mercury capture from 20% total mercury removal (without the additive) up to 60% removal (with the additive).
