Demister Pad Work Theory:
1.A vapor stream carrying entrained liquid droplets passes through a demister pad. The vapor moves freely through the knitted mesh.
2.The inertia of the droplets causes them to contact the wire surfaces and coalesce.
3.The large, coalesced droplets formed in the mesh ultimately drain and drop to the vessel bottom.
