Research on the Dispersant Effectiveness with the Action of Waves

Abstract. Oil spill dispersant, as a kind of effective measures to deal with oil spill, has been widely used, but the effectiveness still needs more investigations. In this paper, what factors influenced the dispersant effectiveness was studied in the tank with the action of waves of different time intervals, and dispersant relative content in oil slick and oil concentration in seawater were mainly the two aspects to examine the phenomenon of dispersant away from oil and dispersion of oil spill. The results showed that the degree of dispersant away from oil increased over with the wave action time, but oil dispersion had not obvious regulation with it. It was speculated that, in actual seawater body waves prompted dispersant to be away from oil, but can also maintained the dispersion effectiveness. This research provided certain technical support for comprehensively and objectively evaluating the dispersant effectiveness
