Knitted Wire Mesh Demister Pads

Demister pads, also known as mist eliminators, are devices made from layers of knitted wire mesh. They are installed in process vessels to capture and coalesce liquid droplets entrained in a gas or vapor stream. This process prevents liquid carry-over, protecting downstream equipment and ensuring product purity.

Knitted wire mesh is used in a wide range of applications, including oil and gas refining, chemical processing, and pharmaceutical manufacturing. It is a critical component in mist eliminators, filters, scrubbers, and EMI/RFI shielding gaskets due to its durability, high efficiency, and customizable properties.

Demister pads are commonly manufactured from corrosion-resistant materials like Stainless Steel 316 (SS316). However, they can be produced from a wide range of alloys and polymers to suit specific chemical and temperature environments. The material choice depends on the application's unique operational conditions.

Yes, customization is a key advantage. Demister pads can be fabricated in various shapes (round, rectangular) and sizes to fit specific vessel dimensions. Other customizable parameters include wire thickness, mesh density, and material type, allowing for performance optimization based on flow rates and particle sizes.

Selecting the right demister pad involves considering factors like the gas flow rate, liquid load, required removal efficiency, and operating pressure and temperature. Our engineering team can assist you in analyzing these variables to recommend the optimal design and material for your specific process requirements.

The effectiveness of knitted wire mesh lies in its complex, three-dimensional structure. This creates a tortuous path for the gas stream, forcing liquid droplets to impact the wire surfaces. The droplets then coalesce into larger drops that drain away by gravity, effectively separating the liquid from the gas.
