Working principle of coalescing filter

 The highly dispersed emulsified water particles are coalesced (combined) into larger water droplets, and particulate contaminants are filtered out. Tiny water droplets contact and adhere to the glass fiber filaments. The flow pushes the droplets along the line until they reach the intersection of the line, where they combine (coalesc) with other droplets into large droplets. These large droplets are then brought to the outer surface of the ink cartridge. Having a higher specific gravity than hydrocarbon fluids, they are released and gravity pulls the droplets to the bottom of the container. The larger the droplets, the faster and more efficient they fall. Generally, particle removal efficiency increases with coalescence efficiency. This is through the use of tighter and finer filter media. The flow direction is from the inside of the cylinder to the outside of the cylinder. This minimizes surface velocity and helps prevent water droplets from breaking and being carried downstream.

Advantages of coalescer

1. It is cost-effective to remove particles and emulsified water from hydrocarbon fluids

2. Integrated design, easy to install and replace

3. Choice of threaded base or open end ink cartridge

4. Choose all-glass fiber media or a combination of glass fiber and pleated media. Field-proven performance

5. Continuous qualification testing to meet changing commercial and military requirements

6. Used as the first-stage Filter Element of a filter or separator

7. Remove particulate matter and coalesce water into large droplets

application

1. Remove water from petroleum products: gasoline, diesel, kerosene and liquefied petroleum gas.

2. Separation of water and hydrocarbon condensate, petroleum refining intermediates, naphtha, propane and propylene.

3. Removal of moisture in aromatics

4. Oil-water separation
