What is a fiber bed mist eliminator?

A fiber bed mist eliminator is an industrial gas-liquid separation device that removes submicron liquid droplets (0.1–3μm) from gas streams using a packed bed of fine PTFE or glass fibers. It achieves >99.96% mist removal efficiency through inertial impaction, direct interception, and Brownian diffusion.

What is the difference between a fiber bed and a wire mesh demister?

Wire mesh demisters capture coarse droplets larger than 3–5μm by inertial impaction. Fiber bed mist eliminators capture submicron droplets (0.1–3μm) with >99.96% efficiency, making them ideal for sulfuric acid, chlor-alkali, and corrosive fine acid mist applications.

What materials are used for sulfuric acid service?

For sulfuric acid mist elimination, PTFE (polytetrafluoroethylene) fibers are used for maximum chemical resistance. Shell materials typically include PP, FRP, or alloy steel with PTFE lining for high-temperature concentrated acid.

Why source fiber bed mist eliminators directly from the Filtearth factory?

Sourcing directly from Filtearth eliminates 20% to 35% intermediary trading markups and avoids communication delays. Plant managers and EPC contractors gain direct access to our core filtration engineers for superficial velocity and pressure drop (ΔP) simulations, custom alloy fabrication, and mill test certificates.

Can Filtearth provide drop-in replacements for existing Brink or FLEXIFIBER candle filters?

Yes. Filtearth manufactures custom-engineered candle filters that fully match the dimensions, flange types, pressure drop profiles, and efficiency ratings of major original equipment brands, enabling seamless installation without modifying existing tower internals or vessel tubesheets.

What fiber media is used in Filtearth fiber bed mist eliminators?

Filtearth uses specialized technical fibers custom-selected for extreme chemical resistance and temperature stability. For high-concentration sulfuric acid, chlor-alkali wet chlorine, and corrosive gases, the fiber bed density is precision-wound to achieve optimal Brownian motion diffusion with sub-micron mist capture above 99.9%.

What information is required to get a sizing and pressure drop calculation?

To calculate the required number of candle elements and predicted pressure drop (ΔP), we require: actual volumetric gas flow rate (Am³/h or ACFM), operating temperature, operating pressure, gas composition, acid mist loading (mg/Nm³), and target allowable pressure drop limit.

What is a fiber bed mist eliminator?

A fiber bed mist eliminator is an industrial gas-liquid separation device that removes submicron liquid droplets (0.1–3μm) from gas streams using a packed bed of fine special technical fibers or PTFE. It achieves >99.96% mist removal efficiency through inertial impaction, direct interception, and Brownian diffusion.

What is the typical mist capture efficiency of a fiber bed mist eliminator?

For submicron droplets smaller than 1μm, our fiber bed mist eliminators reach an efficiency of up to 99.96%, significantly outperforming conventional wire mesh demisters.

Can Filtearth provide replacement elements for existing vessel installations?

Yes, Filtearth manufactures custom aftermarket replacement fiber bed elements dimensionally and aerodynamically matched to existing vessel installations without requiring piping or flange modifications.
