Abstract

ABSTRACT A new laboratory method using a turbidimetric technique has been developed to study basic oil-in-water dispersion processes and oil spill chemical dispersant effectiveness. A simple dynamic turbidimeter was interfaced to a microcomputer, and rates of oil dispersion and oil droplet resurfacing were recorded and correlated to experimental parameters such as oil-to-water ratio and dispersant-to-oil ratio. The new technique was found much more sensitive than classical effectiveness methods and experimental results were in excellent agreement with a mathematical model developed a few years ago to predict oil spill dispersant effectiveness. The method was also found very useful for studying dispersant formulation.
