Product Specifications

Technical details and manufacturing context for Demister/Mist Eliminator

Definition
A critical component within Gas Cleaning Plants that separates entrained liquid droplets from gas streams through impingement, centrifugal force, or filtration mechanisms, ensuring clean gas output and preventing downstream equipment damage.
Working Principle
Operates by forcing gas streams containing liquid droplets through mesh pads, vanes, or cyclonic separators where droplets collide with surfaces, coalesce into larger droplets, and drain away by gravity while clean gas passes through.
Common Materials
Stainless Steel, Polypropylene, Fiberglass

  • Mesh pad thickness or vane spacing (mm) Per Request
Components / BOM
  • Mesh Pad Part
    Primary separation surface where droplets coalesce
    Material: stainless steel
  • Support Grid Part
    Structural framework holding mesh pads in place
    Material: carbon steel
  • Drainage System
    Channels collected liquid away from gas stream

Downstream Applications
Specialized Tooling

Application Fit & Sizing Matrix

Operational Limits
pressure: Up to 100 bar (standard), higher with reinforced designs
flow rate: 0.5 to 50 m/s gas velocity (optimal range)
temperature: -40°C to 400°C (typical), up to 600°C with special materials
slurry concentration: Up to 10% solids by weight (standard), higher with specialized designs
Media Compatibility
✓ Natural gas processing (amine contactors) ✓ Chemical reactor off-gas streams ✓ Compressed air systems
Unsuitable: High-viscosity liquid entrainment (>500 cP)
Sizing Data Required
  • Gas flow rate (actual m³/h)
  • Droplet size distribution (microns)
  • Required separation efficiency (%)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Plugging/Fouling
Cause: Accumulation of solids, polymers, or viscous materials in the mesh or vanes, often due to inadequate upstream filtration, process upsets, or chemical reactions within the mist stream.
Structural Damage/Blowout
Cause: Mechanical failure of the mesh, pads, or support structure due to excessive pressure drop (ΔP), liquid overloading, corrosion, or fatigue from cyclic operation or vibration.
Maintenance Indicators
  • Sustained high differential pressure (ΔP) across the demister, exceeding design limits.
  • Visible liquid carryover or excessive mist in the outlet stream, indicating reduced separation efficiency.
Engineering Tips
  • Implement regular monitoring of differential pressure (ΔP) and trend analysis to detect fouling early and schedule cleaning before efficiency drops critically.
  • Specify and install appropriate upstream devices (e.g., inlet baffles, pre-filters) to remove large droplets and particulates, reducing the load on the demister and minimizing plugging and erosion.

Compliance & Manufacturing Standards

Reference Standards
ISO 14644-1:2015 (Cleanrooms and associated controlled environments) ANSI/ASME B31.3 (Process Piping) DIN EN 13445-3 (Unfired pressure vessels - Part 3: Design)

Frequently Asked Questions

What materials are best for demisters in corrosive chemical environments?

For highly corrosive environments, polypropylene or fiberglass demisters offer excellent chemical resistance. Stainless steel (grades 304 or 316) works well for moderate conditions. Material selection depends on temperature, pressure, and specific chemicals in your process.

How does the drainage system in a mist eliminator work?

The drainage system collects liquid droplets captured by the mesh pad and channels them away from the gas stream. Proper drainage prevents re-entrainment of liquid, maintaining separation efficiency. Systems typically include collection channels, drains, and sometimes pumps for continuous removal.

What maintenance is required for industrial demister pads?

Regular inspection for fouling, corrosion, or damage is essential. Cleaning may involve washing with appropriate solvents or water blasting. Replacement intervals depend on operating conditions, but typical industrial demisters last 2-5 years with proper maintenance and monitoring of pressure drop.

Can I contact factories directly on CNFX?
