Effect of temperature and type of dispersant on treating oil spills

Abstract

Dispersant is a chemical surfactant which can break down an oil from the water surface. Therefore, dispersant can be used to treating oil spills. The effectiveness of dispersant as oil emulsifier can be influenced by the temperature of the environment and concentration of oil and dispersant. This paper shows the influence of temperature variations, dispersant types and layers of sea water on oil spills by testing the light absorbance using spectrophotometer UV-Vis. The results of the experiments show that the biggest light absorbance occurs on the water surface at temperatures of 26° C C with area absorbing of 82.15 abs. Meanwhile, the smallest light absorbance is at temperatures of 16° C with wide absorbance 25.72 abs on the type of dispersant soluble. Wide light absorbance total greatest namely 26° C temperatures on the type of soluble with wide absorbance total 133.49 on three points of layers of water.
