Durable Anti Corrosive Compact Wire Mesh Demister Pads for Gas Liquid Separation
Product Overview
Durable Anti Corrosive Compact Wire Mesh Demister Pads for Gas Liquid Separation are engineered demisting elements intended to remove entrained liquid droplets and aerosols from gas streams while keeping vessel internals compact. Using a layered, graded wire matrix the pads promote impingement coalescence and drainage so condensate returns to the process stream rather than being carried downstream. Designed for continuous industrial service the product combines mechanical robustness corrosion resistance and low flow resistance for energy efficient separation.

Typical Applications
• Scrubbers and absorbers in chemical and petrochemical plants
• Knockout drums and gas processing vessels
• Steam separators and boiler drums
• Vapor recovery units and fractionation towers
• Offshore topsides and marine separation modules
• Environmental emission control equipment
Key Features
• Compact Modular Cartridges — low profile pads fit into tight internals and are easy to handle during installation and service.
• Graded Multilayer Packing — coarse to fine layers trap larger droplets first and progressively remove finer mist reducing re-entrainment.
• Material Flexibility — metallic and nonmetallic options allow selection for aggressive chemistries or food grade applications.
• Predictable Pressure Loss — engineered pore distribution delivers consistent performance across a range of superficial velocities.
• Rugged Construction — reinforced frames and secure fixation prevent movement under pulsation and vibration.
Advantages
• Reduces downstream corrosion and fouling protecting heat exchangers compressors and instrumentation.
• Lowers operating costs by minimizing pressure drop and reducing purge losses.
• Shorter maintenance windows due to modular replacement and simple cleaning procedures.
• Rapid retrofit capability for existing vessels avoiding major mechanical modifications.
• Full material traceability and performance test reports supplied with each shipment.
Manufacturing & Quality Control
Wire is precision knitted or woven, then layers are assembled and compacted to meet the specified density. Pads are set into frames or bonded to support grids as required. Quality checks include dimensional verification coating adhesion (if applicable), material mill test reports (MTR), and sample pressure drop/separation tests at reference velocities. Nonmetallic elements are tested for thermal and chemical stability.
Installation & Maintenance
Install modules into support rings or cradle systems with orientation marks visible to ensure correct drainage direction. Allow small radial clearance for thermal growth and ensure uniform inlet distribution using diffuser plates or perforated baffles. Routine maintenance typically consists of periodic inspection and low pressure water or solvent flushing. Severely fouled elements can be removed individually for offline cleaning or replacement.
Options & Accessories
• Holding grids and clamps for vertical/horizontal mounting
• Anti-vibration spacers and lifting lugs
• Integrated vane layers for severe carryover cases
• PTFE lined frames and FDA compatible materials on request
Packaging, Lead Time & Support
Export grade packing with desiccant and corrosion inhibitor is standard. Typical lead time 12–25 working days depending on material and quantity. Engineering support includes selection assistance sizing calculation and 2D/3D drawing for fit verification.
