Description

Changes in oil composition during chemical dispersion were analysed. A gas chromatographic method was used to study the oil in a water column and also on the surface. The objective of the study was to determine dispersant effectiveness and behavior, and in particular to understand why the effectiveness of surfactants decrease as the oil weathers. It was found that in dispersed oil higher alkanes are present in lower concentration than in starting oil. The higher alkanes are concentrated in the surface oil and are less dispersible. Molecular weight and n-alkane fraction were found to be directly related. It was concluded that the main reason for dispersant effectiveness decrease with weathering is the loss of the highly dispersible small aliphatics which are lost through evaporation. 5 refs., 6 tabs., 3 figs
