Abstract
A method for selecting a demulsifier and its concentration that is most efficient in separating water from oil includes mixing dry oil with a demulsifier to obtain a mixture having a first concentration; generating water droplets inside the mixture; pumping the water droplets and the mixture into a micro-fluidic channel; sending a laser beam through the micro-fluidic channel; recording images of the water droplets in the mixture with a camera; and calculating a percentage of the water droplets that coalescence inside the micro-fluidic channel when free-falling through the mixture, due to gravity.
