Demister
Demister: Comprehensive solution for mist particle separation and industrial equipment protection
Very fine particles of liquids, known as mists, are formed from the contact of liquids and gases under certain conditions. This phenomenon is common in many chemical industry processes and can cause numerous problems for downstream equipment..
To protect sensitive equipment, prevent damage to valuable products, and prevent environmental or process contamination, it is necessary to completely separate these liquid particles from the gas stream.
One of the best solutions for separating mist particles is to use a particle removal device, or demister. However, to select and use this equipment effectively, it is essential to have a thorough understanding of the particle formation process, their size, and how the demister works..
Proper use of demisters not only helps increase process efficiency, but also reduces equipment maintenance costs and minimizes the environmental impacts of industrial processes.
Types of demisters
1. Candle Demister
A demister candle, made of fiberglass or metal fibers, is used to separate very fine particles (1 to 3 microns) from a gas stream. These demisters are designed in a cylindrical shape and their fiber layers are placed concentrically between two shelves. Typically, these equipment are installed inside towers and on tube sheets and provide effective and stable performance. In all types of demister candles, the shelves and fibers are made of different materials based on the application and customer demand.
Applications
- Sulfuric acid production process (intermediate and final absorption tower)
- Chemical processes
- Production of chlorine and hydrogen
- Food production processes
- Paper industries
- Textile
2. Demister mesh pad
Mesh pads are thick woven layers of wire or plastic mesh that are specifically designed to separate liquid droplets from a gas stream. These pads provide effective, economical, and reliable performance. Ava Espikoo Sanat can design and manufacture them in any size required for installation in new or existing process equipment. Mesh pads are usually installed so that the gas flow passes upward through the pad, for optimal separation.

SX Mesh Pads: A sustainable choice for sulfuric acid plants
SX mesh pads are made of a special alloy with very high resistance to corrosion by concentrated sulfuric acid, which has a longer lifespan than conventional materials. Unlike polymers such as PTFE and ETFE, these mesh pads do not experience problems such as deformation or melting. For this reason, many sulfuric acid plants around the world have upgraded their equipment to SX mesh pads.

Why are Ava Espikoo Sanat demisters the best choice?
Demisters are a simple and effective solution to many separation problems in chemical industry processes. Ava Espikoo Sanat demisters help you save time, resources, energy, and space, which results in cost savings.
Save time
Demisters protect downstream lines, pipes, and equipment from corrosion by separating corrosive products from the gas stream. Reduced corrosion results in less need for maintenance and inspection and fewer operational downtimes. Also, the longer operating cycles of demisters minimize downtime and process stoppages.
Saving resources
Demisters help save capital costs by reducing waste of valuable products, protecting equipment from corrosive liquid particles, and extending the life of downstream equipment. Also, using demisters helps meet environmental requirements in your industrial processes.
Energy saving
The advanced design of demisters creates lower pressure drop than conventional models, which leads to a significant reduction in energy consumption and increased process efficiency.
Reduce space requirements
Demisters allow process operation at higher flow rates by preventing the re-formation of bubbles in high-velocity gas streams. This increased flow not only reduces equipment dimensions and channel sizes, but also helps save space and improve overall process efficiency.
