1450mm Mesh Pad Demister Vapor Liquid Separation SS 304L Construction

A mist eliminator is a device usually used in vapor-liquid separator columns, which removes the liquid droplets entrained in a vapor stream. The mist eliminator may be mesh type, vane pack type or other structure intended to aggregate the tiny mist into droplets. So the droplets are heavy enough to be separated from the vapor stream.

The mist eliminator can reduce the residence time required to separate a given droplet size by reducing the volume and cost of separation equipment. The mist eliminators are often used where vapor quality is important in regard to entrained liquids, particularly where separator equipment costs are high (for example, high pressure systems), or where space or weight saved are valuable.

When the marine vessels process the brine by desalination, the brine is flash heated into vapor. In flashing, the vapor carries droplets of brine, that had better to be separated before condensing. Otherwise it will contaminate the vapor with salt. That is what the mist eliminator does. The pure vapor condenses on tubes in the desalination plant, and water is collected from the system.

When properly designed demister pad vapor liquid separators can give efficiency up to 99.9% with minimal pressure drop. Normally demister pads can remove droplets down to 5 microns and lower with a free volume of up to 99% and a surface area of up to 1940 m2/m3. Due to high value of free volume the pressure drop across the demister pad is sufficiently low in most applications.
