Demister Pads: Working and Applications

As gas flows through the pad's complex knitted mesh structure, liquid droplets collide with the wire surfaces due to their inertia. The droplets coalesce into larger drops, which then drain from the bottom of the pad due to gravity, allowing clean, droplet-free gas to pass through.

Our demister pads are typically made from corrosion-resistant materials like Stainless Steel (e.g., SS316). We also offer options in other alloys and polymers to suit specific chemical and temperature requirements, ensuring durability and long service life in harsh industrial environments.

Yes, customization is a key advantage. We manufacture demister pads in various shapes, sizes, and densities to meet specific vessel dimensions and process performance criteria. We can tailor the wire thickness and mesh structure to optimize separation efficiency for your application.

Demister pads are critical in numerous industries, including oil and gas refining, chemical processing, power generation, and pharmaceutical manufacturing. They are used in scrubbers, absorbers, evaporators, and knock-out drums to ensure efficient liquid-gas separation and protect valuable equipment.

A properly designed demister pad can achieve removal efficiencies of up to 99.9% for liquid droplets 5 microns and larger. The exact efficiency depends on factors like gas velocity, liquid loading, droplet size distribution, and the physical properties of the fluids involved in the process.

Maintenance typically involves periodic cleaning to remove any accumulated solids or fouling, which can increase pressure drop. Our pads are designed to be easily removable for cleaning or replacement. The required frequency depends on the service conditions and the nature of the process stream.
