The demister pads function by coalescing smaller liquid droplets to grow bigger by creating an obstruction in the flow path and then isolating them by gravity. When a demister pad is installed in the path of a rising gas stream, the wire meshes create an obstruction. This causes the mist particles to collide with the mesh filament where the mist diffuses on the filament surface to create droplets that follow along the filaments of the two-wire intersection. These droplets stick together and grow bigger and when they are too heavy to rise with the gas stream, they isolate. The gas stream is not affected by the obstruction and can easily escape.
