Dispersant Application Observer Job Aid response

Nov 13, 2018· When initially applied, dispersants sometimes have a herding effect on oil, making a slick appear to be shrinking when, in fact, the dispersant is "pushing" the oil together. This effect results from the surfactant action of dispersants, which exerts a horizontal spreading force on thin oil films.

However, due to the unavaila- bility of suitable viscometers for mineral slurries, the control of mill rheology has been neglected, even though a number of investigators (Austin et al., 1984; El-Shall and Somasundaran, 1984) have determined that rheology has a large effect on the efficiency of both grinding mills and hydrocyclones.

Dispersant effectiveness on oil spills impact of

As the oil weathers and the viscosity increases, the effectiveness of the chemical dispersant declines ( Daling, 1989). Lower water temperature increases the viscosity of both the oil and the dispersant. A higher water temperature usually increases the solubility of dispersants in water, and also affects the spilled oil temperature.
