Knitted Mesh Pad Mist Eliminators
What is a Mist Eliminator?
- The KNITTED mist eliminator is a fabricated pod formed from symmetrical interlocking loops of knitted of metal wire or plastic filaments or any other material in wire form. This pad, with a high free volume and large impingement area, can be installed in any existing or new process vessels to provide separation efficiencies up to 99% for particles down to five microns, with pressure drops in the vicinity of 25 mm WG The KNITTED mist eliminator is a static, in- line device and in the majority of cases it can be installed in the evaporators, scrubbers, pressure vessels etc., without a special housing. There is practically no maintenance required except for cleaning when used in fouling services.
- Most KNITTED mist eliminators are supplied with complete rigid support grids, which allows direct installation onto appropriate supports such as beams and rings within the vessel. Sectional installation allows ease of handling and access through vessel manways.
Working of Knitted Mist Eliminator
- When Vapours carrying mist pass through the KNITTED mist eliminator the vapours pass through layered mesh structure of the KNITTED mist eliminator but the liquid droplets, which have greater inertia, contact and collect on exposed wire surface. As more droplets collect, they coalesce and grow in size until they become large enough to drain back into the system. The overhead product is a pure vapour containing practically no liquid.
Design & Engineering Highlights
- High contact surface area ensures effective separation
- High free volume = lower pressure drop
- Balance between efficiency and pressure drop can be optimised.
- Typically removes droplets down to 5 microns with 99% efficiency
Knitted Mist Eliminator Makes any Good Process Better
- Improves overall process efficiency
- Reduces costly liquid loss
- Controls air pollution
- Low-cost, highly efficient, and versatile solution
DESIGN VELOCITY
- The maximum allowable vapour velocity ‘U’ for most systems is calculated according to the Souder-Brown equation given below.
- It is suggested that the design velocity should be 60-75% the value of ‘U’ so as to allow for surges and upset conditions. However, excellent performance is obtained in most systems for velocities 30-110% of the maximum allowable vapour velocity. For high pressure and vacuum semces the constant K will need to be corrected and the design will be adjusted accordingly. The overall performance of a mist eliminator is a compromise between efficiency and pressure drop. Typically, mist eliminators are specified by means of:
Installation Details
- Can be installed vertically or horizontally
- Sandwiched between a top hold-down and bottom support grid
- Requires support rings and tie wires for secure installation
- Immediate support beams needed for spans >1800–2000 mm
- Flexible installation depending on access location
Side inlet – Top outlet (vertical
flow)
Gas enters from the side, goes up through the mist eliminator, and exits at the top.
Bottom inlet – Top outlet (pure vertical flow)
Gas flows directly upward through the mesh and exits from the top.
Top inlet – Bottom outlet (inverted flow)
Used for reverse setups or where mist may settle down.
Side inlet – Top outlet with central rise
Mist eliminator placed mid-vessel with vertical upflow.
Side inlet with elbow – Top
outlet
A horizontal inlet with a directional change, ensuring mist passes through the eliminator.
Bottom inlet – Top outlet with wide chamber
Gas comes from below and mist is filtered out before exiting upward.
Horizontal inlet – Horizontal outlet with mist pad
Mist eliminator is placed horizontally, effective for side-side gas flows.
Cyclonic separator type
Involves centrifugal action before gas exits, often with an internal mist pad.
Side inlet – Bottom outlet with vertical pad
Mist eliminator installed horizontally; gas flows downward.
Horizontal vessel – Side inlet/outlet
Common in drum-type horizontal vessels where space is limited.
Baffle-style separator
Multiple chambers with wire mesh and baffles for high-efficiency separation.
Liquid-rich system
Used in systems with large liquid loads to prevent re-entrainment.
