Why Demister Vanes Have Low Efficiency & Liquid Carryover
Symptoms · Root Causes · Proven SolutionsVane eliminators fail to capture droplets, causing outlet carryover, tower flooding, downstream corrosion and poor gas-purification results.
What Is Happening?
Vane eliminators fail to capture droplets, causing outlet carryover, tower flooding, downstream corrosion and poor gas-purification results.
Common Symptoms
- Visible mist and droplets at the gas outlet
- Serious liquid carryover in exhaust gas
- Downstream equipment and pipelines corrode faster
- Gas purification and emission indicators fail
4 Root Causes
Vane Fouling
Scale and dust disrupt the designed airflow path.
Poor Vane Geometry
Unoptimized angle and spacing weaken inertial capture.
Installation Gaps
Misalignment creates short-circuit airflow and bypass.
3 Recommended Actions
Control Gas Velocity
Operate within the rated range for reliable inertial separation.
Wash & Descale Regularly
Use online washing to restore clear vane passages.
Upgrade Vane Geometry
Use enhanced multi-fold chevrons for finer droplet capture.
