Knitted Wire Mist Eliminator / Demister
In
many process operations the removal of entrained material in vapour
flows is essential. Knitwire Products provide a wide range of mist
eliminators and demister units suitable for any application. The
principle of demisters and mist
eliminators operation is based on having a large number of obstacles
intercepting entrained droplets in a vapour flow. This large number of
obstacles must provide minimum drop in pressure over the removal system.
Mist
eliminators and demisters are made up from knitted materials with
interlocking
asymmetrical loops of metal or plastic with typical wire diameters
being 0.1 - 0.3mm. By careful choice of wire diameter, Knitwire
Products have produced knitted mesh mist eliminators and demisters with
extremely high free
volumes (typically 98-99%) along with very high removal efficiencies
and low pressure drop.
Along with
wire diameter and mesh density, another important parameter in design
and operation is the vapour velocity. This can be controlled by careful
selection of the mesh area. Optimal area will depend on operating
temperature, pressure and pressure drop. Under normal operating
conditions, 99% + removal efficiency can be achieved with a pressure
drop of less than 250 Pascals.
