SEPARATION MECHANISMS Several different types of mist eliminator are designed for the separation of liquid entrainment. To choose the appropriate equipment, the four basic mechanisms used to capture droplets on a wire or filament must be considered. DIFFUSIONAL DEPOSITION is only effective in the separation of very finely dispersed aerosols with droplets typically smaller than 1µm that is small enough to be affected by Brownian Motion. DIRECT INTERCEPTION assumes the droplet of a given diameter and negligible mass follows the stream line around the target wire or fibre and is separated as it touches the target or collection fibre.

INERTIAL INTERCEPTION considers the droplet mass and predicts how momentum will make it deviate from the gas stream. GRAVITATIONAL DEPOSITION works on the principle that large, slow moving droplets may separate from a gas stream under gravity. This is restricted to large droplet sizes and low superficial gas velocities -making separator dimensions both prohibitively large and uneconomical. Therefore, it can be disregarded as an effective option.
Within the three effective mechanisms, Enhanced mist elimination equipment falls into two groups: Enhanced wire mesh mist eliminators - inertial / direct interception Enhanced vane separators - inertial interception Each mechanism is critically dependent on the droplet size distribution for a given application. A summary of the typical characteristics of liquid entrainment and corresponding equipment groups is shown in Figure 1. |
