Sinking Of Crude Oil Amended-Model Oil Mixtures Due To Evaporative Or Dissolution Weathering On The Surface And Submerged In Water, Cameron Joseph Loebig
Sinking Of Crude Oil Amended-Model Oil Mixtures Due To Evaporative Or Dissolution Weathering On The Surface And Submerged In Water, Cameron Joseph Loebig
LSU Master's Theses
Despite the popular belief that crude oil is a mixture of hydrocarbons that floats on the surface of water, tar balls continue to wash up on beaches from the sea floor years after the Deep Water Horizon oil spill. This is because of the rarely studied weathering effects that occur during deep sea spills. While the evaporative weathering process of oil at the water’s surface has been studied, no currently implemented models assess the weathering effects of dissolution within the water column. The evaporative effects at the sea surface and the dissolution of soluble components within droplets located in the …

Effect Of Surfactant On Dynamics Of A Droplet Released In A Quiescent Medium, Abhijit Rao
LSU Master's Theses
During the ‘Deepwater Horizon’ accident, dispersants were used as one of the remediation methods to mitigate the ill effects of oil that entered the water column. The dispersants lower the interfacial tension at the oil-water interface and cause the large oil droplets to disintegrate into finer droplets which remain dispersed in the water column for longer times. A dispersant typically is composed of a surfactant and solvent. Surfactants are chemical compounds which are chiefly responsible for the lowering of interfacial tension at oil water interface. In this study, we have investigated the effect of surfactant on the dynamics of a …
