Stability Research on the Effect of Oil Spill Dispersant II - Impact of Wave Intensity
نویسندگان
چکیده
The oil spill dispersant (OSD) play an important role to deal with the frequent oil spills in the marine environment, which can effectively reduce the interfacial tension between the oil and the seawater. However, there are many studies showing the stability of the OSD effect changes over time, and is related with the wave. In this paper, the results show the OSD will gradually move away from the oil, and the quantity and speed of the removed OSD is influenced by the intensity and duration of the wave action. The stability mechanism of the OSD effect is proposed in this study. The results of this study provide methods for the research on the stability mechanism of the OSD, as well as the theoretical basis for the comprehensive evaluation and the rational use of the OSD.

With the continuous research and development of the low-toxic and high-efficiency oil spill dispersants (OSDs), there are an increasing number of evaluation methods for the effect of the OSDs. Currently, the majority of the OSDs effect evaluation is related with the testing of the emulsification in the laboratory, while the stability researches on the OSDs effect are still few. In this paper, t...

The U.S. National Research Council (NRC) Committee on Understanding Oil Spill Dispersants: Efficacy and Effects (2005) identified two factors that require further investigation in chemical oil dispersant efficacy studies: 1) quantification of mixing energy at sea as energy dissipation rate and 2) dispersed particle size distribution. To fully evaluate the significance of these factors, a wave t...

The pelagic brown alga Sargassum forms an oasis of biodiversity and productivity in an otherwise featureless ocean surface. The vast pool of oil resulting from the Deepwater Horizon oil spill came into contact with a large portion of the Gulf of Mexico's floating Sargassum mats. Aerial surveys performed during and after the oil spill show compelling evidence of loss and subsequent recovery of S...
