Advanced Entrainment Control
Wire Mesh Demisters utilize precision-woven metal/non-metal meshes (Ø≤0.3mm) to capture 99.5% of liquid droplets down to 1μm. Engineered with >95% void volume and customizable configurations (ring/chevron/withdrawable), they deliver <0.15 kPa pressure drop while eliminating carryover in refinery sour water strippers, chemical scrubbers, and acid gas treatment units.
Core Technology
| Type | Structure | Key Advantage |
|---|---|---|
| Ring Mesh | Concentric wave layers | Standard efficiency (98%) |
| Chevron Mesh | Angled vane stacks | Highest efficiency (99.9%) |
| Withdrawable Mesh | Modular cartridges | Maintenance without vessel entry |
| PTFE Mesh | Non-metallic weave | HF/HCl resistance ≤200°C |
(Material options: SS304/316L/Alloy 20/Hastelloy®/Monel®/PTFE)
