Mist particles & aerosol removal
Phase separation technologies for dust and mist elimination
Demisting: from droplets to submicron liquid particles
In manufacturing processes involving contact between liquid and gas, tiny mist droplets as well as ultra-fine liquid particles called aerosols are carried away with the gas. Within a process, these particles can cause problems such as corrosion of equipment, contamination of product, fouling of heat exchangers, and damage to instruments.
Mist can be formed in manufacturing processes in three different ways:
- Mechanical forces may break up or “atomize” a liquid to form a mist.
- Sudden cooling of a gas stream may result in the condensation of vapor to form a mist.
- Chemical reaction of two or more gases may take place at temperatures and pressures where the reaction products are mists.
Mechanical forces typically create mists with large particles, while particles formed by condensation and chemical reactions are usually very small (submicron).
Mist elimination or demisting can be defined as the mechanical separation of these liquids from gases. Demisters or mist eliminators are specially designed to provide a large surface area in a small volume to collect the liquid droplets without substantially impeding gas flow.
SOCREMATIC demisting technologies
SOCREMATIC has established more than 40 years of experience is mist and aerosol elimination. We are the European distributor for KIMRE™ mist eliminators with brand names KIMRE™ B-GON® or KIMRE™ KON-TANE® as well as the French distributor for BRINK® Fiber bed Mist Eliminators.
For fertilizer application, SOCREMATIC has developed WATMESH® demisters composed of different layers, especially manufactured for SOCREMATIC.

BRINK® fiber bed mist eliminators
BRINK® fiber bed mist eliminators provide a high efficiency removal of aerosols from gas streams where they coalesce the liquid particles collected on the individual micro fibers to form liquid films which are moved through the bed by the gas flow, then drained off the downstream face of the bed by gravity.
BRINK® incorporates a special wound fiber, computer controlled quality, and a patented bi-component design. BRINK® fiber bed mist eliminators excel at collecting the very-difficult-to-remove, submicron-size mist particles that cause visible emissions. Collection efficiencies on sub-micron particles can be designed to exceed 99.5%.
KIMRE™ WATMESH® mist eliminators
KIMRE™ WATMESH® mist eliminators consisting of a uniquely interlaced structure of a monofilament material, are produced in a variety of thermoplastic filament material which allows continuous service from -15°C to 204°C and process corrosion resistance. Various style and layers can be combined into single pad as to meet requested efficiency.
For more than 40 years Kimre Inc. has developed different types of pads with their own geometrical texture and efficiency depending on particles and droplet sizes. The requested efficiency depends on the combination of different pad sized as well as fiber diameter.
Being the exclusive European distributor of KIMRE™, we can propose our WATMESH® mist eliminators for many fields of application.
They come in multiple zones each with a specific surface and density and are especially designed for fertilizer application using an elaborated spray system. Depending on its composition, KIMRE™ mist eliminators offers an extremely low cut-off and high efficiency > 99% @ 1µm.
Used in combination with our KIMRE™ HORIZONTAL CROSS FLOW SCRUBBER, this state-of-the-art and high efficiency solution will further strengthen the overall dedusting efficiency as to obtain extremely efficient polishing demisting system even on very fine and ultra fine particles.
