Refining vacuum towers internal item wire mesh mist eliminator
How does wire mesh mist eliminator work?
When a vapor stream carrying entrained liquid droplets passes through the EIT Mesh but the inertia of the droplets causes them to contact the wire surfaces and be held there briefly. As more droplets collect, they grow in size, run off and fall free. Properly applied to specific process conditions, DEMISTER mist eliminators achieve 99.9% separation of liquid entrainment from any vapor stream, assuring pure product overhead. Pressure drop is usually less than 25.4 mm H2O (1" WC).
Wire Mesh Mist Eliminator Standard Specification:
2.Design
2.1General
A.Size, style, thickness, configuration, and materials are specified in XXX Project Specification – Vessels.
B.Mist Eliminator styles are defined as follows:
C.Style G is a mesh blanket having a variable knitted density. The vapor inlet section is the least dense and the outlet section the densest. Typical inlet/outlet knitted mesh densities are 5 lb/ft3 (80.1) and 9 lb/ft3 (144.2). The customer can require variable density blankets having slightly different knitted densities and wire diameters.
Style V is to be determined by the vendor, based on the process conditions provided by customer. Vendor may determine the mist eliminator type best suited to meet the mist elimination requirement. The selected style may include a mesh pad, vane or a combination of mesh & vanes. The mist eliminator may be oriented vertically, horizontally or at an angle determined by the vendor. A single pad of variable knitted density may also be applied.
