Elessent® Brink® Fiber Bed Mist Eliminator

Treating Sub-Micron Mist Emissions

Sub-micron mist emissions are a leading cause of visible stack opacity, corrosion damage, odor complaints, and environmental citations in industrial air pollution. Brink® Fiber Bed Mist Eliminators from Elessent® are advanced air pollution control systems designed to effectively remove:

Fine aerosols and acid mists (SO₃/H₂SO₄, nitric acid, hydrochloric acid)

Oil smoke and VOC condensables

Sub-micron droplets and soluble solids in gas streams

By capturing these fine particles, Brink® solutions protect downstream equipment, extend service life, reduce maintenance costs, and ensure strict compliance with industrial emission regulations.

The Brink® Mist Eliminator

A Brink® industrial fiber-bed mist eliminator is a high-efficiency air pollution control device engineered to capture sub-micron aerosols, fine mist, and industrial emissions. By targeting droplets smaller than one micron (<1 µm), Brink® mist eliminators provide reliable mist removal in demanding process industries.

This advanced fiber-bed design incorporates a patented MECS® drainage layer, which ensures that collected liquid drains freely from the fiber bed. This suppresses re-entrainment, prevents plugging, and keeps pressure drop (ΔP) stable over time — delivering long service life and retrofit-friendly integration.

This advanced fiber-bed technology ensures effective control of:

Stack plumes

Corrosiove aerosols

Odor causing emissions

Regulated pollutant

By eliminating these fine aerosols, Brink® mist eliminators deliver cleaner exhaust gas, reduce airborne corrosion risks, minimize odor complaints, and ensure stable operation at the lowest possible pressure drop (ΔP). Compared to mesh pads or vane separators, Brink® fiber beds achieve superior sub-micron mist capture efficiency—up to 99.95%—while maintaining long service life and retrofit-friendly designs.

Fine Mist Problem

Fine mist forms when vapors condense or when chemical reactions generate sub-micron droplets (<1 µm). These extremely small particles are invisible to the naked eye, yet remain highly persistent in process gas streams, making them especially difficult to capture and control.

Common sources of fine mist include:

Acid production (phosphoric, sulfuric, nitric acid mists)

Fertilizer manufacturing (ammonium nitrate, urea, phosphates)

Chlorine and hydrochloric acid (HCl) processes

Metallurgical operations (zinc, copper, molybdenum, lead, nickel, steel)

Organic chemical production (PVC, styrene, polyethylene, flooring, roofing, laminating)

Desulfurization and incineration (coke production, soil remediation, waste treatment)

New energy technologies (green hydrogen, battery production, CO₂ capture and storage)

Why Brink® Mist Eliminator

Proven Technology: captures sub-micron aerosol

High performance: up to 99,95% removal efficiency

Low ΔP: continuous drainage prevents plugging

Long service life: Outlasts conventional fiber beds

Retrofit-friendly: made to fit in existing vessels

How it works

The Brink® Fiber Bed Mist Eliminator removes fine mist and aerosols using well-understood physical principles.

Brownian diffusion dominates for droplets below 0.3 µm, where random molecular motion forces particles into contact with the fibers.

Interception occurs when larger droplets follow the gas streamlines but still touch and adhere to the fibers.

Impaction captures droplets with enough inertia to deviate from the gas flow and collide directly with the fiber surface.

Together, these mechanisms ensure efficient removal across the full particle size spectrum. Once captured, droplets merge (coalesce) into films along the fibers and are drained away by gravity — a process supported by the patented MECS® drainage layer, allowing the Brink® mist eliminator to maintain high sub-micron capture efficiency in continuous operation.

Recent developments

In ammonium nitrate (AN) and ammonia service, conventional glass-fiber mist eliminators degrade quickly due to alkaline attack, resulting in short lifetimes and frequent replacements. While glass fibers perform adequately in acid mist environments such as SO₃/H₂SO₄, they are not suited for alkali-rich conditions.

The new Brink® Vulcan® Fiber solves this challenge by providing resistance to both alkali and acid exposure. This makes it the ideal choice for fertilizer production and other alkali-heavy processes, where standard fiber beds fail prematurely.

Key advantages of Vulcan® Fiber include:

Superior durability in alkaline environments (AN, NH₃, caustics)

Reliable sub-micron mist control without rapid fiber deterioration

Longer operating cycles and fewer shutdowns for replacement

By addressing the alkali resistance gap, Vulcan® Fiber extends the proven performance of Brink® mist eliminators into applications where glass fiber simply cannot keep up.
