A Quantitative Study of the Chlorine Atom Concentration in Plasma
Chlorine can oxidize elemental mercury to a species soluble in water. The addition of chlorine gas into an electrostatic precipitator, used to remove particulates from flue gas may increase the mercury removal efficiency in the precipitator. The determination of the chlorine atom concentration, formed inside the precipitator, is a key to the evaluation of this efficiency. A series of experiments were performed to dissociate the chlorine gas in a corona-discharge field formed inside a 10 cm x 3 cm Pyrex tube at one atmosphere. Chlorine atoms formed were measured by reacting them with hydrogen and chlorine concentration was determined as a function of voltage supplied, chlorine injected and distance between the electrodes. This data could help in optimizing the amount of chlorine reagent gas needed to obtain enhanced mercury removal efficiency in an electrostatic precipitator.
