Geothermal steam demisters must control mineral-bearing brine carryover as well as ordinary liquid droplets. Silica and salt deposition, flashing entrainment, steam pressure drop, drainage, vessel level, and long-term cleanability are key design considerations.

Venturi scrubbers generate fine droplets and high liquid loading by design, often with captured solids inside the droplets. Downstream mist elimination may require bulk separation, vane stages, polishing media, strong drainage, fouling tolerance, and careful pressure-drop control.

Semiconductor acid exhaust scrubbers may require PP or PVDF mist eliminators with low pressure drop, good chemical resistance, fine-droplet control, and strong fouling tolerance. Mixed chemistry, variable tool flow, salt formation, compact layout, and exhaust-system pressure balance should all be considered.

Thermal desalination demisters prevent salt-bearing brine droplets from contaminating distillate. Vacuum operation, high vapor volume, strict product purity, chloride corrosion, scaling, drainage, and bypass control make the application especially demanding.

Biogas and H₂S scrubber mist eliminators must account for variable gas flow, downstream sensitivity, water condensation, sulfur or salt fouling, chemical compatibility, and limited blower pressure. Mesh, vane, or staged separation should be selected from the real process duty.
