AMACS - Mesh Mist Eliminators
Mist elimination, or the removal of entrained liquid droplets from a vapor stream, is one of the most commonly encountered processes regardless of unit operation. Mesh mist eliminators are fabricated as multiple layers of knitted wire mesh, wherein the crimped strips are stacked to form a pad with a specific density and thickness. Rigidity is provided by a high open area frame, usually metal, consisting of a grid on each side and rods passing through the mesh
It is a physical separating device that works on the principle of impaction and retention, and is widely used in the industry due to its cost effectiveness and high impaction characteristics for smaller size droplets. The knitted wire media provides surface area for entrained liquid droplets to strike wherein each strand acts as an obstruction around which gas must flow. Within a very short distance upstream of a filament, the gas turns aside sharply but some mist droplets are unable to follow. They strike the filament, adhere, and coalesce to form droplets that are large enough to trickle down and fall away.
