WHAT IS COALESCING FILTER?

Using a coalescing filter or you can say coalescing filtration is the process of separating two phases of matter from a fluid stream. For instance, the coalescing filtering process can separate gas from aerosols and water droplets. You can let air-containing liquid impurities pass through with the aid of the coalescing filter element.

Demand for water vapour-free air has increased in response to the need to prevent these catastrophic issues, and numerous solutions have been developed to supply operations with water-free air that is suitable for all applications throughout the operation.

TYPES OF COALESCING FILTERS:

There are mainly two types of coalescing filters:

Electrostatic Coalescers: Electrostatic Coalescer uses an AC, DC, or a combination of both currents to cause droplet coalescence in fluid mixes. By applying an electric charge to the fluid, electrostatic coalescers destabilise the emulsion and enlarge the molecules, forcing them to fall into a collection tank for drainage.

For this reason, AC currents in the 50–60 Hz range are typically employed. As a result of the forces of attraction created by the produced electric field, the fluid molecules condense to form heavier molecules. For separating water-fuel emulsions in offshore oil and gas production facilities, electrostatic coalescers are frequently utilised.

Mechanical Coalescers: Mechanical coalescers use a series of filter components or barriers instead of electrostatic charges to separate things instead. In order to separate water vapour from hydrocarbon condensate, mechanical coalescers can coalesce the water molecules into bigger particles that are subsequently drained from the system.

The filter element's selectivity determines the final product's purity after separation. Microfibers made of borosilicate and membrane technology are frequently employed in the production of filter elements.

FUNCTIONS OF COALESCING FILTERS:

Coalescing filters are effective at removing specific water droplets, compressor lubricant, and other particles; but, they are unable to completely eradicate water vapour from the compressed air system. Air enters the system through the filter housing and then passes through the filter cartridge as part of the coalescing process. Clean air leaves through the outlet hole as the coalesced mixture of water and oil accumulates into the drainage bowl.

Several coalescing filters may need to be installed at various locations throughout the compressed air system, depending on the application.

Installing coalescing filters after the receiver tank is advised. Though it doesn't really matter, you should think about keeping the two components close to one another for ease. To know more about such, and how it can help in your process, you can get in touch with a reputable coalescing filter manufacturer.

BENEFITS OF COALESCING FILTERS:

• Improvement in the working condition on a shopfloor since the Coalescer eliminates bacterial growth, which causes a foul smell.
• By using a Coalescer oil-water separator, you will be able to reduce the consumption of fluids by 70%.
• The separation of oil from water-based process fluids results in a cleaner process throughout the shop. Cleaner process fluids reduce their consumption and make the entire manufacturing process extremely efficient.
• It ensures the smoother running of equipment and reduces maintenance requirements.
• Low-Pressure drop.
• Large filtration area by pleated design.
• Easy to operate and maintain.
• Positive end caps sealing to prevent bypass.
• Customized design.
• High dirt load holding capacity.

CONCLUSION:

As we know the problem comes with a solution. So here is a solution for your problem coalescing filter. We have talked about coalescing filters and how it works and why they should be used. A general-purpose filter must be installed upstream of the coalescing filter in addition to fittings, tubing, and brackets. A coalescing filter needs to be maintained and repaired once a year or when the visual service life indication turns red, whichever comes first. Similarly, related to the application of sintered filters, you must go through the details and all that to define how it can benefit you and how to maximize its functionality for your use purpose.
