Is demister pad the same as mist eliminator?

Demister pad and mist eliminator are two essential components in various industries where the removal of mist and droplets from gases is required. While they may seem similar in their functions, there are some key differences between the two. In this article, we will explore whether demister pads are the same as mist eliminators.

What is a Demister Pad?

A demister pad, also known as a mist pad or wire mesh pad, is a device used to remove mist and droplets from a gas stream. It consists of layers of knitted mesh or wire mesh arranged in a grid pattern. When the mist-laden gas flows through the demister pad, the mist droplets are captured on the mesh surface, allowing the clean gas to pass through.

Demister pads are commonly used in industries such as chemical processing, oil and gas, pharmaceuticals, and power generation. They are effective in removing liquid droplets from gas streams, preventing equipment corrosion, protecting downstream equipment, and improving overall process efficiency.

What is a Mist Eliminator?

On the other hand, a mist eliminator is a more generic term that refers to any device or component used to remove mist and droplets from a gas stream. Mist eliminators come in various forms, including demister pads, vane pack separators, fiber bed filters, and cyclonic separators.

While demister pads are a type of mist eliminator, not all mist eliminators are demister pads. Mist eliminators may use different mechanisms such as impingement, coalescence, or filtration to remove mist and droplets from gas streams.

Differences Between Demister Pad and Mist Eliminator.

One of the main differences between a demister pad and a mist eliminator is the construction and material used. Demister pads are typically made of wire mesh or knitted mesh, while mist eliminators can be made of various materials such as metal, plastic, or fiber.

Another difference is in the efficiency and particle size removal. Demister pads are highly efficient in removing mist droplets down to submicron sizes, making them ideal for applications where fine mist removal is required. Mist eliminators, on the other hand, may have varying efficiencies depending on the type and design.

Additionally, demister pads are more commonly used for liquid-gas separation applications where droplets need to be captured and removed from the gas stream. Mist eliminators, on the other hand, can be used for a wide range of applications beyond just liquid-gas separation, such as odor control, VOC removal, and particulate removal.

In conclusion, while demister pads are a type of mist eliminator, they are not the same. Demister pads are a specific type of mist eliminator that uses wire mesh or knitted mesh to capture mist droplets from gas streams. Mist eliminators, on the other hand, can encompass a range of devices and components used to remove mist and droplets from gases using different mechanisms and materials.
