Product Description

PTFE Wire Mesh Demister Screen Gas Liquid Separating

 

1. How Wire Mesh Demister Works?

 

 

 

1.1 Wire mesh demisters work based on the principles of impingement and coalescence. When a gas-liquid mixture enters the mesh pad demister, the gas flows through the wire mesh surface while the liquid droplets are captured by the wire surfaces due to the surface tension and capillary action.

1.2 As the liquid droplets accumulate on the wire surfaces, they coalesce into larger droplets due to gravity, and eventually, they become heavy enough to fall down to the bottom of the demister. The larger droplets then flow down the surface of the mesh pad and are collected in a liquid sump. The gas stream, now with a much lower liquid content, exits the demister and continues on in the process.

1.3 The effectiveness of wire mesh demisters depends on several factors, including the wire mesh type, wire diameter, pad thickness, and gas velocity. Higher gas velocities can increase the turbulence in the gas-liquid mixture, which can increase the likelihood of liquid droplets impinging on the wire surfaces. However, increased turbulence can also lead to increased pressure drop across the demister, which can reduce the overall efficiency of the process.

1.4 Wire mesh demisters are commonly used in various industries, including oil and gas, chemical processing, and power generation, to remove liquid droplets from gas streams. They are also used in environmental applications, such as air pollution control, to remove liquid droplets from exhaust gases before they are released into the atmosphere.

 

 

2. Wire Mesh Materials

 

2.1 Metallic Mesh Pads

Materials for metallic Mist Eliminators are as per customer need. Type 304 or Type 316 mesh pads can be in accordance with ASTM A-478. Monel mesh pads can be in accordance with ASTM B-164.

2.2 Non-metallic Mist Eliminators

Non-metallic Mist Eliminators shall be PTFE or polypropylene as specified in by customer.

2.3 Supports

A.Supports welded to the vessel shall be the same material as the shell. Where the shell is lined, supports welded to the lining shall be the same material as the lining.

B.Supports not welded to the shell (e.g. beams) shall be the same material as the Mist Eliminator.

2.4 Grids

A.Metallic grids can be the same material as the mesh pad

B.For non-metallic mesh pads, the grids shall be carbon steel, coated with the same material as the mesh pad.

2.5 Fastening Devices

A.For metallic mesh pads the wire ties or other fastening devices shall be of the same material as the Mist Eliminator.For non-metallic mesh pads, the grids shall be carbon steel, coated with the same material as the mesh pad.

B.For non-metallic mesh pads the wire ties can be the same material as the mesh pad.
