Frequently Asked Questions

Demister Pads or Mist Eliminators mostly used for preventing product loss, guarantee filtering efficiency, and to avoid equipment damage. Typically, demister pads are mounted at the top of the vessel before an outlet of the product. They are widely used in cooling towers, ventilation systems and air scrubbers too. Mist eliminators can be also used in the various applications where acid mist, alkaline mist or oil mist gets produced.

As the liquid droplets passes through the demister pad which carried by gas, they coalesce and form large droplets which drain back into the system. The large droplets are heavy in the nature comparatively to vapours and gets trapped in the demister pad. This device prevents toxic chemicals and liquids to be released to the environment. The contaminated vapours needs to clarify before it goes out of the vessel. Further, it can lead to corrode the system, can damage electrical systems and can create potentially dangerous work environment.

Working Principle-

Whenever there is a contact between gas and liquid in the column, there will be maximum chances of entrainment. It&#;s just entrapment of one substance by another one along with contaminants. Such mist and liquid droplets cannot be vented off directly to the atmosphere. And it can lead to serious losses of the process fluid and equipment damage in mass transfer operations.

This entrained component can be easily get separated by using demister pad. This pad can directly convert entrained vapours/mist into liquid and traps the vapours to get vented off with gas. It helps to collect entrained vapours in the form of liquid drops and separates it from gaseous mixture. The main working principle of Demister is to separate liquid by coalescing smaller liquid droplets from the gasses and allow it to get drop into the liquid pool.

When mist in the gas rises at constant speed, then the mist eliminator works where, vapour strikes the mesh surface filament and liquid start coalescing. After some time, liquid droplet size goes up and it gets isolated from the filament.

Coalescing of smaller liquid droplets is due to different types obstructions made in the path of vapours. It allows vapours to pass through obstruction where the pressure drops created in the vapour leads to formation of liquid droplet, and only gasses to flow from the demister device by the mechanical separation.

Demister pad can also be called as mist eliminator, mist pad, wire mesh demister, catching mist and mesh mist eliminator also. Demister pad can install directly on the outlet of the top vapour or at the top of the packing tower.

Easy Installation and setup

A perfectly designed and fitted demister pad will be easy to install, and results into minimal downtime. Demister Pads are uniquely engineered and assembled for particular application as per the client&#;s requirement. A well-engineered pad will be highly efficient resulting in low pressure drop and fouling. The Manufacturing materials of the pads are able to withstand at elevated temperature and having corrosion resistance property. This allows it for long lasting, minimum cost and higher production in the plant operations.

Efficiently Eliminates the Mist

Demister pads are extremely effective when it comes to removal of entrained liquid droplets from contaminated vapours with liquid droplets.Mist eliminator can remove nearly 100% of solvent losses or emissions if the device is properly installed, efficiently designed and constructed of durable materials.

Shapes and Sizes

Mist eliminators can be designed in all sizes and shapes for vertical or horizontal flow as per process requirement. They can be designed to fit over any sized equipment to create the disturbances in the path of toxic gasses in the outlet system.
