Effect of contact angle on equilibrium saturation during mist filtration in nonwoven and foam media

Abishek, S.; Mullins, B.; King, A.; Kasper, G.; Heikamp, W.

Abstract:
Coalescence filtration using knitted, foam or nonwoven fibrous media is the widely applied in the industry for separation and recovery of liquid mists that are generated in many processes, including lubricated machining, compressors and engine crankcases. The dynamics of multi-component/ phase fluid transport and its interaction with the filter surface at the pore-scale and the contact angle dynamics are expected to significantly influence performance and efficiency of filtration processes. Most mist filters currently used in the industry are hydro- or oleophillic in nature, even though it is expected that philic filters will develop higher steady state saturation levels compared to phobic media. For hydro- or oleo-phobic media, it can be expected that once steady operation is reached, the total level of saturation in the filter media will be significantly lower, thus providing advantages in lower pressure drops and better overall performance. However, phobic media may possibly result in greater levels of aerosol re-entrainment and a greater potential for clogging by (other) solid particles since parts of the filter may not be fully ... mehr
