Suppression of emissions from large electrolytic tanks by means of fine, charged water droplets (phase I)

The authors present theoretical considerations and laboratory experimental results of an electrostatic system designed to suppress tank emissions at their source, i.e. at the surface of the tanks. It is found that tank emissions in the form of a mist are substantially reduced by being repelled back into the tank. The reductions measured in terms of copper, nickel, cobalt, iron, sulphuric acid, and arsenic were all on the order of 50%, except for the iron and sulphuric acid data which show approximately a 20% reduction for the sulphuric acid, 60% for the iron when spraying charged water.<>
