Yingdu Demister is a professional manufacturer engaged in producing and exporting of demister pads
Wire Mesh Demister pads are advanced vapor filtration systems that are used in oil and gas applications to reduce droplet size. They are composed of a metal mesh or wire screen mounted on a support structure, often made of foam. The metal mesh is designed to remove droplets from a liquid stream, which is why it is used for oil and gas applications. The metal mesh can range from very fine to coarse, depending on the application. It is also important to consider the wire structure, as it affects the permeability of the material and the size of the droplet that can be removed.
Wire Mesh Demister pads are most often used in oil and gas processing, refining, and storage. They can be used to remove droplets ranging in size from 2-20 microns, allowing the user to achieve very precise separation of liquids and vapors. In addition, they have the ability to filter out larger particles, including suspended solids, which can cause clogging and other issues in downstream systems.
The specification parameters of a Wire Mesh Demister pad will depend on the application. Generally, the metal mesh and wire structure need to be selected based on the properties of the liquid being processed, such as viscosity and temperature. Additionally, the size of the demister pad and the thickness of the mesh will also play a role in determining how effective it will be at removing droplets.
The installation and maintenance of a Wire Mesh Demister pad is relatively straightforward. Generally, the support structure should be secured to the process vessel using tie rods and bolts. Once the structure is correctly installed, the mesh will then be stretched over it and securely clipped into place. It's important to ensure that the mesh is securely held in place as any loose wires could result in an inadequate separation of liquids and vapors. To maintain a Wire Mesh Demister pad, simply inspect it regularly for signs of wear and tear, and replace any parts that may have become damaged.
Overall, Wire Mesh Demister pads are an advanced and effective method of vapor filtration. Their ability to remove both small and large particles make them ideal for oil and gas applications, where even the smallest droplets can cause problems in downstream systems if not removed. With the right specification parameters, installation process, and proper maintenance, a Wire Mesh Demister pad can provide years of reliable service.
Features:
1. It shows 99% efficiency under general conditions and velocity (1~3m/sec or higher).
2. Over 98% open area is guaranteed under any conditions so pressure drop caused by the use of the demister can be disregarded (0.1”~1.0 W/G).
3. It can be made of any material suitable for the given temperature and corrosion-resistance.
4. It is possible to install by use of M/H so it is easy to handle.
5. There is no restriction in the conditions, place, and size for use. It is installable on the existing systems.
6. Self-cleaning is possible. It is semi-permanent so it is economical.
DEMISTER Materials (Mesh Pad type)
It can be made of various materials, depending on its use, and its major materials are as per the below:
1. SUS304, 304L, SUS316, 316L, MONEL
2. P.P (POLY PROPYLENE), P.E (POLY ETHYLENE), TEFLON
3.GLASS FIBER
Fixing Methods & GRID
The demister should be horizontally fixed and supported. At the bottom or both the top and the bottom, a support grid which is welded with FB 25X3t, RB6Ø of the same material as that of the demister pad at proper intervals (APP150mm), is used. For fixing the grid and the pad, RB6Ø or 1.6Ø tie wire is used.
Dust Collectors - The dust collector of a wet type has excellent collection capacity.
PRESSURE DROP
In the case of using the demister, the pressure drop is estimated at 0.1“~1.0”W/G. Theoretically, it can be calculated out based on the below equation
