KnitMesh wire mesh mist eliminators have an excellent track record as a low cost, highly versatile and efficient method of removing liquid entrainment from gas streams. They are produced as a bed of knitted mesh which presents a tortuous path and large surface area to the droplets entrained in the gas stream. Separation is achieved by impingement on, and capture by, the filaments of the mesh where the droplets coalesce and drain.

Installation can be made in a variety of ways but gas flow is usually either vertically upwards, with the liquid draining counter-current to gas flow, or horizontal, with the liquid draining in a direction normal to the gas flow.

KnitMesh offers standard designs which are ideal for routine applications, providing excellent separation efficiency down to droplet sizes as small as 2 microns, and with a pressure drop typically less than 2.5mbar.

 

Most KnitMesh wire mesh mist eliminators are supplied complete with rigid support grids, which allow direct installation onto appropriate supports such as beams and rings within the vessel. Sectional installation allows ease of handling and access through vessel manways.

Accessories such as tie wire, bolting, clamps and support beams can be supplied where necessary.

For more demanding applications, KnitMesh has developed sophisticated modelling techniques which move mist eliminator design away from conventional industry ‘rules of thumb’ and provide:

	Optimised structure
	Tailored features e.g. fibre material, free volume and mesh pattern for specific process requirements
	More precise method of performance prediction over a range of possible inlet conditions
	Ability to consider effects of changing drop size distribution and liquid hold-up
