Cover Story: Airborne submicron oil droplets (oil mists) often occur as undesired contaminants in industrial applications and have to be removed to prevent air pollution or grant health protection at workplaces. In industry, these oil mists are separated by coalescence filters.
The separated oil can take different shapes on the filter and may influence the separation efficiency. As filtration velocities can vary in industrial applications, the impact on the gas velocity on these separated structures needs to be characterized. Utilizing a µ-CT, oil deposits are quantified and compared at three application-orientated filtration velocities. The results indicate that there is no influence of the filtration velocity on the local oil distribution. It is assumed that the oil structures formed by coalescence are dominated by the wetting properties of the fibers. View this paper
