Geometric characterization of wire mesh mist eliminators (Id 358)

The mass transfer is thus dependent on intensive counterflow interaction between the vapor and the liquid. The resulting turbulent flow causes droplets to be torn from the liquid phase by the vapor phase. This reduces the separation efficiency (energy efficiency and product quality) of the process. Simultaneously, droplets carried over to downstream equipment lead to corrosion, polymerization or fouling and increase component maintenance requirements.
For this reason, wire mesh mist eliminators are frequently used in practice. These separate entrained droplets as they pass through the close-meshed wire mesh. Characterization of their separation efficiency, capacity and pressure drop are essential for design and application. The focus of the work is the experimental determination and mathematical description of the pressure drop for knitted wire mesh separators as a function of their geometric properties.
