ELECTRIC CHARGE GENERATION DURING TANK WASHING: INFLUENCE OF CONTAMINATS AND ELECTRIC FIELD STRENGTH ON CHARGE GENERATION

The charging rate of an aqueous solution depends on the type and concentration of the dissolved compound. In agreement with a simple charging model, surfactants produce a charged mist with a polarity corresponding to their ionic nature. The charge densities found for sea-water/crude oil mixtures depend very much on the water/oil ratio. Twenty to thirty per cent of crude oil in water, on the one hand, and about ten per cent of water in crude oil, on the other, increase the charge density significantly above the values for the pure liquids. For pure sea-water, the charge production is limited by the electric field strength due to charges present. At the place of mist formation, a limiting value of about 1900 V/m is found.
