Brink® CGF - Compressed Gas Filter

Remove oil and water from compressed air and gas.

The Problem:

Submicron oil and water particles are present in gas streams following industrial compressors. These mist particles are formed by evaporation and condensation due to the heat of compression and from lubricant blow-by, if lubricated compressors are used. 

The water can accumulate in air lines and freeze in cold weather. The water and oil can damage downstream instruments, tools, airveying membranes and contaminate final product. If a desiccant dryer is used, the oil and water particles will over load and reduce the life of the desiccant.


The Solution:

The MECS Compressed Gas Filter (CGF) utilizes a combination of low operating velocities, deep beds, and Brownian diffusion as the predominant collecting mechanism to achieve high efficiency with very long operating life and low pressure drops. With the standard CGF, 99.5% of the submicron mists are removed. (Models are available to achieve 99.95+% removal). In typical compressed air service, CGF operates 10-15 years, which is much longer than replaceable coalescing filters. Pressure drop is typically less than 0.5 PSIG which provides appreciable operating power savings over coalescing filters. The CGF can also tolerate high inlet loadings caused by temporary upsets or surges.
 

How It Works:

The MECS Compressed Gas Filter consists of special glass fibers packed between screens or perforated plates. As the compressed air (or other gas)containing oil and water particles passes through the fiber bed filter, the particles collect on the fibers by impaction and Brownian diffusion. These particles agglomerate and form into liquid films which are moved to the outside surface of the filter by gas drag. Gravity moves the collected liquid down the filter and into the sump where it is drained off by a liquid trap or timed solenoids.

 

NOTE: While the CGF will provide reliable and very high efficiency collection of the smallest liquid particles, no filter will collect oil or water that remains as a gas due to vapor pressure. In some situations, removal of gases, oil or water by desiccant dryers or carbon absorption will be necessary.

 

MECS’s compressed gas filter will provide reliable and very high collection efficiency of the smallest liquid particles.

Custom CGF Systems

For larger flows outside the range of the standard CGF-01 through 12 or where height limitations in retrofit installations exist, custom, multiple CGF element vessels can be designed. In many cases, customers group several

CGF - 01 thru CGF - 07, CGF - 08 Thru CGF-12

compressors together with a common CGF System, resulting in capital cost savings and allows for greater operational flexibity without affecting efficiency of the CGF System. MECS has extensive experience in a full range of Multiple CGF Unitaerosol mists, be it mineral oil spray or submicron sulfuric acid mist. To compliment this, MECS mechanical engineers and designers are specialists in corrosion resistant materials of construction and high reliability, heavy duty vessel and CGF fabrication techniques.
