High Efficiency Fiber Demister With Mesh Filter Material
Introduction of fiber demister :
The fiber demister also known as a fiber mist eliminator or fiber bed filter, is a device used to remove fine liquid droplets or mist from a gas stream. It plays a crucial role in separating entrained liquids from process gases in a variety of industries.
The fiber demister consists of two concentric screens or parallel flat screens filled with compressed fiber pads.
Fiber demister are individually designed and manufactured with enclosures made of a variety of alloys, thermoformed plastics or fiberglass reinforced plastics.

Key characteristics and features of fiber demisters:
High Efficiency:
Fiber demisters can achieve very high removal efficiencies, typically greater than 99% for droplets down to 1-2 microns in size.
The efficiency is dependent on factors like fiber diameter, bed depth, and gas velocity.
Low Pressure Drop:
The open, porous structure of the fiber bed results in a relatively low pressure drop across the demister.
This helps minimize the energy required to move the gas stream through the system.
Features of fiber demister :
Reduce or eliminate visible chimney plume.
Design capacity can be adjusted without limitation.
Ensure that the pressure drop is less than 40 mm (1.5 ") W.G.
Interchangeable with existing fiber pad equipment.
Capture submicron particles with a diameter of 0.1 micron or less.
They are used to remove entrained liquids like acids, solvents, and hydrocarbons from various process gas streams.
Natural Gas Processing:
Fiber demisters are employed in natural gas processing plants to remove water and hydrocarbon condensates from the gas stream, protecting downstream equipment like compressors and pipelines.
Oil and Gas Production:
In oil and gas production facilities, fiber demisters are used to separate oil mist and water droplets from the gas stream, enabling efficient operation of compression equipment and gas treatment systems.
