The demister (or mist reducer) is a device inserted
into the filters for a liquid and vapor separation in order to obtain the
separation of liquid drops from the gas stream.
The use of the demister reduces, therefore, the residence time requested for the separation in the apparatus, and this translates into a smaller volume of the equipment and a reduction of the installation costs.
The demister filter may contain different types of
filtering materials as a function of the pollutants to be removed. Furthermore,
they can be designed by providing more filtration stages with progressive
abatement in order to obtain a total air purification.
The materials used for the realization can be different: carbon steel, stainless steel and special austenitic ferritic steels such as Duplex, Super Duplex, Nickel alloys and Titanium Gr. 2, considering also the conditions in which the filters operate.
The main area of application is the removal of oil
mists in the mechanical industry.
We can design this type of filter for many applications but the principal one is the removal of liquid particles.
The filter elements can be realized in all type of metallic materials.
of gas: Industrial, Oxygen, Hydrogen, Nitrogen, Air, Natural gas.
This type of filters is used for scrubber plans and metering skids for natural gas purification before turbine.
They are often installed after a double stage filter.
