Product Specifications

Technical details and manufacturing context for Mist Eliminator

Definition
A mist eliminator is a critical component within a quench tower that separates liquid droplets from the gas stream after the quenching process. It prevents liquid carryover into downstream equipment, protects compressors and heat exchangers, reduces emissions, and improves process efficiency by ensuring only clean gas proceeds through the system.
Working Principle
As the gas stream containing entrained liquid droplets passes through the mist eliminator, the droplets impact on the surfaces of the eliminator elements (such as mesh pads, vane packs, or fiber beds). The droplets coalesce into larger drops that drain by gravity back into the quench tower sump, while the cleaned gas continues upward.
Common Materials
Polypropylene, Stainless Steel, Fiberglass
Technical Parameters
  • Mesh pad thickness or vane pack spacing (mm) Per Request
Components / BOM
  • Mesh Pad
    Primary droplet capture surface made of knitted or woven filaments
    Material: Polypropylene or Stainless Steel
  • Support Grid
    Structural framework that holds the mesh pad in place
    Material: Stainless Steel
  • Drainage System
    Channels collected liquid back to quench tower sump
    Material: Stainless Steel
Engineering Reasoning
0.1-10 bar differential pressure, 0-150°C temperature, 0.5-50 m/s gas velocity
Differential pressure exceeding 12 bar causing structural deformation, liquid loading exceeding 0.15 kg/m²·s causing re-entrainment, gas velocity exceeding 60 m/s causing droplet shatter
Design Rationale: Excessive pressure differential causing plastic deformation of mesh/packing materials, Stokes number mismatch (Stk < 0.1) causing droplet bypass, Kelvin-Helmholtz instability at gas-liquid interface causing re-entrainment
Risk Mitigation (FMEA)
Trigger Corrosive gas composition (e.g., H2S > 50 ppm, Cl2 > 10 ppm) attacking metal components
Mode: Mesh wire thinning and breakage, reducing separation efficiency below 99.5%
Strategy: 316L stainless steel construction with PTFE coating, corrosion allowance of 1.5 mm minimum
Trigger Liquid loading exceeding 0.12 kg/m²·s causing film flooding
Mode: Liquid carryover exceeding 0.01% by mass, downstream equipment contamination
Strategy: Drainage channels with 45° minimum slope, demister pad with 97% minimum void fraction

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Fouling and Plugging
Cause: Accumulation of solids, salts, or viscous materials in the mesh or packing, often due to inadequate upstream filtration, process upsets, or condensation of heavier hydrocarbons.
Structural Degradation (Corrosion/Erosion)
Cause: Chemical attack from corrosive process streams (e.g., acidic gases) or physical erosion from high-velocity liquid droplets or entrained particulates, exacerbated by material incompatibility or excessive gas velocity.
Maintenance Indicators
  • Significant increase in pressure drop across the mist eliminator (measured via differential pressure gauge), indicating flow restriction.
  • Visible liquid carryover or 'spray' from the vessel outlet, or audible 'sloshing' or gurgling sounds downstream, signaling failure to separate entrained droplets.
Engineering Tips
  • Implement and maintain robust upstream filtration (e.g., coalescers, strainers) to reduce particulate loading and fouling potential on the mist eliminator element.
  • Specify corrosion-resistant materials (e.g., 316L stainless steel, alloys like Hastelloy, or plastic coatings) matched to the process chemistry, and ensure gas velocities are kept within the manufacturer's design range (typically 2–15 ft/s for mesh pads) to minimize erosion and re-entrainment.

Frequently Asked Questions

How does a mist eliminator work in chemical manufacturing processes?

Mist eliminators remove liquid droplets from gas streams through three primary mechanisms: impaction (droplets collide with mesh fibers), interception (droplets are caught by fibers as gas flows around them), and diffusion (small droplets move randomly and adhere to fibers). This ensures clean gas output and prevents contamination or equipment damage.

What materials are best for mist eliminators in corrosive chemical environments?

For corrosive environments in chemical manufacturing, stainless steel (especially grades like 316L) offers excellent corrosion resistance, while polypropylene provides chemical inertness and cost-effectiveness for less aggressive conditions. Fiberglass is suitable for moderate corrosion resistance with lightweight properties. Material selection depends on specific chemical exposure, temperature, and pressure requirements.

What maintenance is required for mist eliminator systems?

Regular maintenance includes inspecting and cleaning the mesh pad to prevent clogging, checking the drainage system for proper liquid removal, and ensuring the support grid remains structurally sound. Maintenance frequency depends on operating conditions, but typically involves visual inspections during shutdowns and pressure drop monitoring during operation to detect fouling early.
