Dispersant effectiveness (DE) Test to determine the Conformity of Bio-OSD Product Standards with Applicable Regulations by Swirling Flask Test
Abstract
Oil pollution in coastal areas due to oil spills was an environmental problem
that needed to be anticipated. Since the role of a dispersant in the spill response was to
intensify the process of dispersing oil in water with further stabilization of the resulting
dispersions, its most important characteristic was the dispersing ability, essentially
expressing the effectiveness of the dispersant. This capstone project aimed to
determine the conformity of Bio-OSD product standards with applicable standards.
The method used to test the effectiveness of dispersants was the swirling flask test.
The dispersant effectiveness of Bio-OSD on Crude oil X, Y, and Z was 100%, 88.5%,
and 82.3%, respectively. The dispersant effectiveness of Commercial OSD-X on
Crude oil X, Y, and Z results was 39.8%, 49.9%, and 64.6%. It could be concluded
that the effectiveness of the Bio-OSD product met the standards proposed by the
Environmental Protection Agency (EPA), which were at least 45%.
