In many process operations the removal of entrained material in vapour flows is essential. Knitwire Products provide a wide range of wire mesh mist eliminator units suitable for any application.
The refining process 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.
Extremely high free volumes
Wire mesh mist eliminator units 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 mist eliminators 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.
Plastic or stainless steel wire mesh mist eliminators
We also offer this product manufactured from ETFE or other plastics, such as Polypropylene, PVDF and PFA, in both a monofilament and a multifilament. Our ETFE mist eliminator units work very similarly to our stainless steel wire version, however many people will choose to have a plastic product for highly corrosive environments as opposed to the stainless steel alternative which is best suited to high temperatures.
The ETFE mist eliminators can withstand high temperatures of up to 260 degrees celsius. Its chemical resistance promotes uses in corrosive environments such as fertiliser production or sulfuric acid.
Our specialist design team with over 40 years of experience are always more than happy to assist you and find solutions to any problems that you may be experiencing. We are extremely flexible with materials, wire diameters and sizes, meaning that no problem is too big or too small.
