Demister FAQ Section
What is the typical lifespan of your Demister units?
Our standard Demister units typically last 5-8 years in normal operating conditions, depending on the application environment. For highly corrosive environments, we recommend our premium 316L stainless steel models which can extend service life to 10+ years with proper maintenance. Regular inspection and cleaning every 6-12 months will maximize the Demister's operational lifespan.
How do you determine the correct Demister size for my application?
Proper Demister sizing requires several factors: gas flow rate (actual m³/h), operating pressure and temperature, liquid loading (kg/m³), and desired efficiency. Our engineering team uses proprietary software to calculate the optimal Demister dimensions based on your specific process parameters. We recommend providing complete system specifications for accurate sizing recommendations.
Installation Guidelines
For optimal Demister performance, follow these installation best practices:
- Ensure proper vertical alignment within the vessel
- Maintain recommended upstream straight-run distances
- Use appropriate gasketing materials for your process conditions
- Verify adequate support structures for large-diameter units
- Perform pre-installation inspection for transport damage
Performance Data
| Droplet Size (μm) | Removal Efficiency (%) | Pressure Drop (Pa) |
|---|---|---|
| >100 | 99.9% | 50-100 |
| 50-100 | 99.5% | 100-150 |
| 10-50 | 98% | 150-200 |
Can your Demister handle high-velocity gas streams?
Yes, our specially designed high-velocity Demister models can effectively process gas streams up to 7 m/s without significant re-entrainment issues. These models feature reinforced mesh structures and optimized packing densities. For velocities exceeding 7 m/s, we recommend our vane-type Demister configuration which maintains efficiency at gas velocities up to 12 m/s in certain applications.
Maintenance Procedures
To maintain peak Demister performance:
- Schedule regular visual inspections (quarterly recommended)
- Monitor pressure drop increases (>20% indicates cleaning needed)
- Use approved cleaning methods (steam, chemical, or mechanical)
- Replace damaged sections promptly to prevent efficiency loss
- Maintain proper records of maintenance activities
