Demister pad, in its name, it is a pad-shape device to remove the mist from gas streams. It is also called mist collector or mist eliminator. It is a product as the resolution result of entrainment. In every process involving contact between liquid and flowing gas, tiny mist droplets are carried away with the gas. This phenomenon is called entrainment.
Beginning about 1947, special devices were developed to remove mist from gas streams, they are now known as demister pad or mist eliminators. These devices provide a large surface area in a small volume to collect liquid without substantially impeding gas flow. Demister pad coalesce (merge) fine droplets and allow the liquid to drain away. Gas typically flows upward through a horizontal mist eliminator. Createch offers a full line of mist collectors including continuous duty centrifugals.
Demister pads are used to collect light mist and swarf. A number of design layouts and filter choices are provided for both flexibility and expandability.
Demisters consist of pad sets, or a variety of pleated panels. The filter media is normally knitted wire mesh made of metal or synthetic fiber.
Knitted wire mesh demister pad is supplied in standard, high efficiency and high permeability. Demister Pads are essentially porous blankets of carefully knitted wire mesh designed and constructed to efficiently abate mist particles. Demister pad is mainly used to eliminate streams with diameter of more than 3μm to 5μm.
*Efficient and economical
*Porous blankets of knitted metal or plastic wire mesh can be custom-designed for specific applications
*Demister pad is Ideal in absorption and drying towers, evaporators, distillation towers and a wide ranges
*High collection efficiency
*Low pressure drop
*Lowest installed cost.
More recently, advances in technology have enabled substantial progress in mist eliminator designs, materials, and Applications expertise. New products and methods of use have been found highly effective for many purposes, especially the following:
Downsizing new vessels;
Improving product purity;
Cutting operating costs;
Reducing environmental pollution;
Reducing downstream corrosion;
Increasing recovery of valuable liquids.
