Mesh drop separators can make complete solutions (case with droplet / wire mesh) with specially designed supports and/or cover grids supplied to support the mesh pads. The droplet separator can be a custom designed enclosure constructed for the corresponding process data designed. This design can make the free inflow area reaching approximately 90 %.
Wire mesh can be used as a droplet removing elements in gas streams, as oil mist separators, air filters, insulation mats or coalescence separator for phase separation of immiscible liquids.
The wire mesh droplet eliminators (demisters) are made of fine wires with different wire diameters generally ranging between 0.1 mm and 0.5 mm.
Drop / droplet separators / demisters can be used for dehumidification, i.e., for the separation of the liquid phase from a gas stream. The drop separator should catch gas or vapor flow drops.
It is designed to clean exhaust air streams to erosion, sediment and product contamination.
Major parameters for the design of a drop separator:
Parameters needing to be considered when design:
- Flow rate in m³/h; m³/h; kg/h
- Operating pressure in bar
- Operating Temperature in C°
- Initial flow direction (vertical or horizontal)
- Droplet size in microns
Important Data Sheet (Two Parts: Process Data and Mechanical Data) Provided for Demister Droplet separator:
First Part: PROCESS DATA
The demister separator working process description: A mixed fluid (Crude+Water+Gas) enters to the vessel in order to separate the gas from the liquids. The gas leaving this vessel goes to the compressor. It is required to catch all the liquids going to the compressor with the using of designed drop separator.
VAPOR OR GAS: Fluid: Gas
Major Operating data:
Flow rate at operating conditions lb/h
Density at operating conditions lb/ft³
Entrained Liquid: Crude plus water
Density at operating conditions
Viscosity at operating conditions
Entrained Liquid Aprox. Amount
For the demisters or drop separators:
Desired collection efficiency;
Retained particle size;
Types of Mist Eliminator;
Maximum allowable pressure drop across elements, in psi
Calculated pressure drop across elements, in psi
Material: stainless steel or other material

Mist Eliminator Installation method
Available Space in the Vessel
When installing the wire mesh separators, the eliminator pad must fit tightly to the wall of the column to prevent any gas leaking through.
