Wire Mesh Demister pads or Mist eliminators are porous blankets of metal or plastic knitted wire mesh, designed and constructed for the efficient, economical removal of entrained liquid droplets from vapor streams. Demister Pads can be fabricated in any required size and shape and may be installed in new or existing process vessels.
HOW IT WORKS?
When vapor and entrained liquid droplets pass through a mist eliminator, the vapor moves freely through the mesh pad but the liquid droplets, due to their greater inertia, cannot make the necessary sharp turns and as a result are thrown into contact with the wire surfaces and briefly held there. As more droplets enter the pad and collect on the wires, they grow in size, run down the wire to the bottom surface of the mesh separator and fall from the unit. Overhead vapor is now free of entrained liquid.
PTFE wire mesh demister applications:
Reduce loss of valuable chemicals: demister pads markedly cut glycol, amine, or solvent consumption in absorption and regeneration towers.
Increase throughput capacity: demister pads allow a significant increase in throughput anywhere gases and liquids come into contact in process equipment.
Improve product purity: demister pads prevent contamination of side draws and overheads in refinery atmospheric and vacuum towers and other distillation columns.
Minimize contamination: demister pads can prevent the poisoning of expensive downstream catalysts or provide boiler feed water quality condensate from evaporator overheads.
Provide equipment protection: demister pads protect turbine, blower, and compressor blades, which can eliminate serious maintenance problems.
Reduce air pollution: demister pads help diminish droplet emissions to environmentally acceptable levels.
