Abstract
The development of a laboratory system for the study of the long term behavior of crude oil on a water surface is described. The apparatus consists of a cylindrical glass vessel containing water which is rotated at 33 rpm, thus creating a concave surface in which oil tends to accumulate at the center. Turbulence is induced by a stationary stirrer. Results are described of tests conducted with a number of crude oils and it is concluded that the system is able to create reproducible conditions of controlled evaporation, dissolution, turbulence, photolysis, and oil in water emulsion formation. A major advantage of the system is its simplicity and robustness which permits prolonged exposure of the oil to simulate weathering, over periods of weeks and months. A second system is described which can be used to determine the concentrations of dissolved hydrocarbons under oil slicks by in-situ headspace analysis. A prototype submersible sparger sampling system was devised and tested, and results are presented. It is concluded that the system is a promising and practical method of determining the extent to which dissolved hydrocarbons are present in water at various depths under an oil slick. In both cases it is concluded that the
