SkimOil Air Compressor Condensate Oil Water Separator

Overview

CCS Air Compressor Condensate Oil Water Separator This oil water separator is designed to handle air compressor condensate. This separator has NO moving parts and is nearly maintenance-free. It’s designed to give turbulent free plug flow for maximum oil-water separation.

A large turbulence-free separation chamber provides sufficient residence time for coalescing gravity separation, and the effluent header design and placement ensure maximum residence time for separation. Rugged construction, proper selection, and a proven design will assure you of a clean discharge, eliminating the concerns of environmental compliance.

How Air Compressor Condensate Oil Water Separator works:

Inside of your air compressors, there is a built-in oil-water separator (OWS) that separates the water from the oil that stays inside the compressor that is used to lube the rotary screw and other internal parts. In addition to this built-in OWS, you will also need to use an external oil-water separator (CCS-OWS), designed to keep you from sending oil into the environment via the actual condensate liquid that leaves the compressor.

There’s a lot of oil out there….  Let’s keep it in the right places!

During the compression process, outside contaminants such as water vapor, dirt, junk and dust are mixed in with the hot oil. Once the air has cooled down at the end of the compression process, the contaminated condensate is generated.

If this moisture collects anywhere in the distribution system (mainly air receivers, filter bowls or moisture separators), the condensate will get into the compressed air system and cause damage to the pneumatic equipment/system and possibly ruin or cause quality problems with the final product.

Typically a good portion of this condensate winds up going to the lowest spot in the plant’s air delivery system…..such as the scale pits in steel mill operations.  Because of this unavoidable, inconvenient and VERY expensive by-product of using compressed air, an oil-water separator is necessary and beneficial to any compressed air operation.

Environmental concerns have produced tough new standards to follow and stiff penalties for those who don’t comply. Most states now consider air compressor condensate as a hazardous waste. In other areas, it is at least considered to be a special oily waste, with discharge limits to POTWs or municipal treatment plants. Some plants have it hauled off.

CCS Oil/Water Separator Specifications

The 3 Stages of separation:

• Two large turbulence-free separation chambers provide adequate dwell or residence time for gravity differential to affect the separation process. When water enters the first chamber the fluid is forced to go through the coalescer pack where the small oil particles are coalesced and separated from the clean water. Clean water from the bottom chamber is gravity-fed to the second chamber where the action is duplicated for better separation.
• A second stage of gravity separation plus coalescing media (polypropylene balls or tubes) provides greater turbulence-free residence time for further separation.
• A large volume External activated carbon polishing filter (GAC) provides clean and sheen-free water for discharge. Almost all sewer districts accept water from a carbon filter.
  As indicated above, coalescing, gravity separation and carbon absorption are the three separation methods used by the Compressor Condensate oil water separator (CCS).

Wait….  I have some condensate with oils that don’t separate. What now?

Some lubricants such as poly glycols and phosphate esters have a specific gravity (SG) equal to or even greater than water. Because of the higher specific gravity, special equipment is required to separate these oils from the water.

Also, keep in mind, that lubricants that are miscible with water (poly glycols) or contain additives (ATFs) such as detergents which cause the lubricant (oil) to form stable emulsions with water, and cannot be separated using any ordinary type gravity separation devices.

See the purpose-built ConEVAP….designed to evaporate your condensate away with:
NO EMISSIONS NO MOVING PARTS NO KIDDING NO MORE WATER

Water is water at 211 degrees F and at 212 F it’s turning to vapor. Evaporate it away.
See the simple BUBBA PROOF ConEVAP compressor condensate evaporator with only one moving part.

With some compressor oils …gravity and coalescing separation are impractical even impossible. Some compressor oils are designed to go into solution and be impossible to separate. In that case, the condensate has to be hauled off or even evaporated into the atmosphere. Usually, compressor oils will boil off at 600 + degrees F, which would allow you to evaporate the water and leave the compressor oil behind.
