Mesh demister, also called gas liquid separator or mist eliminator or coalescing mesh pads, is a specially designed device to separate liquid droplet from vapour steams. It is mainly used to separate liquid droplets with diameter of 3μm-5μm and larger in separation towers.

Mesh demister efficiency is preliminary a function of droplets size, wire size, specific surface area of the mesh, pad thickness and physical properties of the system. For a standard specification mesh demister ( wire ø 0.28 mm, density 145 kg/m³, surface area 300 m²/m³ ) removal efficiency is typically 100 % for a droplets 5 μm and greater in diameter. Higher surface area mesh demister 500 m²/ m³ using a reduce wire diameter 0.15mm can be used to improve the removal efficiency.

Mesh demister can be installing either horizontally or vertically. With horizontal gas flow through the demister the capacity is 305 greater than compared to vertical flow, thus the demister can be smaller.
Mesh pads are typically 150mm thick with 25mm thick grids on either side making on overall thickness of 200mm. Many years of experience have shown that a 150 mm pad thickness provide optimum performance in hydrocarbon process with a vertical gas flow configuration.
