Mist Elimination

Mist Elimination

PLASTICNET has been refining mist elimination technology for decades, and working closely with customers in a diverse range of industries to address the specific problems that occur.

 

Mist eliminators are designed to remove contaminants from process air emissions that evolve as mist droplets. These contaminants can include oil mist, machine coolant mist, chromic acid mist, sulfuric acid mist, and other entrained mist.

Failure to effectively capture these mists often leads to higher contaminant emissions, production losses, corrosion of downstream equipment, and increased maintenance.

 

The most common demister technologies include chevron separators and knitted wire-mesh demister. Chevrons are characterized by high liquid holding capacity, but limited collection efficiencies for fine mist droplets below 20 microns (µm); the knitted wire-mesh demister is composed of wire or fiber into mesh-pad composition structure, provides collection efficiencies for mist droplets down to 3-5 microns in size but has a low liquid holding capacity and is easily clogged with insoluble contaminants.

 

PLASTICNET’s mist eliminator is constructed of thermoplastic monofilament fiber into a step-ladder interlocking 3D three-dimensional conical weaving structure. It is directional and almost all fibers are perpendicular to the direction of the air flow to maximize the contact with the entrained droplets in the gas stream.

This conical alignment creates a change in the vapor flow through the eliminator structure which provides maximum mist elimination effectiveness through impaction, interception and centrifugation.

 

PLASTICNET’s Mist Eliminator provides the highest performance of any mesh-type mist eliminator with efficiencies as high as 99+ percent removal of 1 micron mists. Also, due to the high percentage of perpendicular fibers, the pressure loss through the media is significantly lower as compared with conventional knitted mesh demist filters of the same efficiency.
