Pressure drop of mist eliminator

Pressure drop of the mist eliminator is defined by the following equation [3]  

AP = dry pressure drop, kPa f = friction factor 8 = void fraction 

Other terms have been defined earlier. 

Friction factor f depends on the Reynolds number, and Table 3.6 can be used to estimate the friction factor [3]. 

In case of a horizontal separator, significantly higher gas flow can be achieved in comparison to vertical gas flow, simply because, in the horizontal mode the liquid can easily drain downwards due to gravity. This is the reason the vane type mist eliminator is very popular in horizontal separators.
