METHOD AND SYSTEM FOR TESTING OIL SPILL DISPERSANT EFFECTIVENESS

摘要

This invention relates to a system and a method for testing oil spill dispersant effectiveness, in particular in the context of oil spill dispersants, more particularly marine oil spill dispersants. In one aspect, the invention relates to a system for testing the oil spill dispersing effectiveness of a dispersant, the system comprising: a)a vessel for containing a liquid; b)at least one injector, said injector being configured to dispense an adjustable flow of an oil-based fluid at the bottom of the vessel; and c)at least one of.a liquid turbidity assessment system comprising a laser beam emitting device and a detector, and 2.a liquid sampling system. In another aspect, the invention relates to a method for testing the oil spill dispersing effectiveness of a dispersant, comprising: a)dispensing an oil and a dispersant at the bottom of a vessel containing water under stirring; and b)at least one of a. assessing the turbidity as a function of time, b. measuring the average oil droplet size, c. measuring the hydrocarbon concentration, and d. assessing the color, of a water sub-layer located between the top 10% water layer and the bottom of the vessel.
