Como Oil Recycling & Filtration Systems


Oil Recycling Systems

COMO Oil Recycling Systems are High Performance Systems, designed with the versatility to recycle virtually any type of Industrial Oil. Engineered for many years of dependable trouble free service.

Oil Contaminants can have serious problems associated with water and/or particulate contamination. Water contamination in oil produces an emulsion, which accelerates corrosion and causes metal deterioration. Particulate contamination can accelerate wear on vital parts, i.e. pumps, bearing, gears, valves, seals, etc. The presence of water and/or particulate contamination in oil will increase downtimes, labor costs and disposal costs.

Cutting Oil Filtration and Recycling
Cutting oils are believed to act as a lubricant in the interface between chips and the tool reducing friction and aiding in chip flow. The primary reason for the use of cutting oils is for lubrication to reduce process friction. Cutting oils are also employed to increase the rate of heat flow from the machining process, i.e. for cooling to remove any process generated heat. This lubrication and cooling improves the surface finish of the machined work. Additionally, the cutting oil is used to transport any chips away from the cutting zone.

When using cutting oils you may experience any of the following:
    • Unacceptable processed part
    • Excess chips in the "cutting zone"
    • Increased process friction
    • Elevation in process temperature
Particulate contamination does not mean that the cutting oil must be disposed of and replaced. Through multi-pass filtration, the particulate can be removed from the cutting oil and thus the life of the cutting oil can be increased. Both fine and gross contamination can be removed through the use of multi-pass filtration. COMO Filtration will reduce part cracking and distortions, help reduce process friction and improve finish quality
.

Quench Oil
As any quench oil is used, its inherent properties of heat resistance, hardening ability and finishing quality begin to degrade. This degradation in quench quality is noticed because the quench oil is gradually being contaminated with particulate. Particulate contamination will diminish the quench oil’s resistance to heat, prevent uniform hardening and promote cracking or distortions of steel parts. Additionally, particulate contamination will inhibit a quality finish to steel parts as a sludge buildup is noticed.

Oxidation occurs in a quench oil as it is exposed to air or oxygen. At elevated temperatures, this oxidation occurs at a relatively high rate. Oxidation results in the buildup of organic acids and the formation of insoluble materials or sludge. These insoluble materials increase the viscosity of the quench oil. Thermal cracking occurs as the oil is exposed to elevated temperatures. This thermal cracking results in the formation of new materials; some light, relatively volatile products and some heavy, less volatile products. The light, volatile products lower the flash point of the oil. The heavy, less volatile products increase the viscosity of the oil. You may be experiencing any of the following with your quench oil:
    • Diminished resistance to heat
    • Increased oxidation
    • Increased thermal cracking
    • Non-uniformed hardening
    • Deterioration in hardness or finish
    • Sludge build-up
    • Uneven cooling on parts

Air Strip Technology Now Available on COMO Oil Recycling Systems
The addition of Air Strip technology moves COMO Oil Recycling Systems ahead of vacuum oil purifiers in cost effectiveness and energy efficiency. COMO Oil Recycling Systems now offer water removal rates and dryness levels equivalent to vacuum systems with lower costs, complexity, and energy usage. Water removal rates are greater than one gallon per hour and final dryness levels of less than 40 ppm water are easily achieved. The addition of air stripping technology to our re-cycling systems makes it possible to economically dry oils that tend to retain emulsified water.

Air stripping is a "mass transfer" operation using dry air as a conveyor belt to remove water from oil. The oil is heated to 150 degrees Fahrenheit or more and finely dispersed air is injected. The air is immediately heated to the temperature of the oil, and in so doing, its "relative humidity" drops to the point where it is able to absorb up to its own weight or more in water. The higher the temperature of the oil, the greater the amount of water the air can remove. The rate of water removal with air stripping is determined by the temperature of the oil and the amount of air flow. 5 cfm of air with an oil temperature 160 degrees will remove one gallon of water per hour. Other volatile contaminants are also removed by this process.

How does Air Stripping compare with Vacuum purifying...
Oil temperatures are about the same in both processes. Oil oxidation is generally not a factor at these temperatures given the short exposure times involved. COMO's Air Strip systems are built on the foundation of our Oil Recycling Systems which all feature an integral oil reservoir. Using this oil reservoir in-stead of attempting to dry the oil in place results in such large energy savings that operation may be possible where it would be impossible to operate a vacuum system.

With Vacuum Purifiers, the oil is drawn from the sump through a heater, passes through the vacuum chamber, and is discharged back to the sump still hot. If the sump is large, most of the heat added to the oil is lost in the reservoir. Most vacuum systems are equipped with heaters that are not capable of raising the oil temperature more than 50 degrees per pass. If the heat loss in the sump is excessive, the oil temperature will never reach the required 150 degrees. The energy required to raise a 5 g.p.m. flow of oil from an ambient temperature of 70 degrees to the minimum required temperature of 150 degrees in one pass is in excess of 21 kilowatts (72,000 btu). At many locations, this amount of electrical power is not available. In contrast, COMO's Model "2000" Air Strip Recycling System can handle 100 gallon batches of oil with only 6 kilowatt heaters, which require only 25 amps at 240 volts single phase or 14.5 amps at 240 volts 3 phase. The amperage requirements at 480 volts will be half these numbers.

Transformer Insulating Oil Recycling
Contamination is the major cause of oil breakdown and subsequent transformer failure. Water and particulate contamination challenge the effectiveness of dielectric properties to maintain minimum 30kv performance to assure expected device life and service reliability. Water is the acid enabling mechanism that reduces TAN (total acid number). Particulate contaminates decrease IFT (interfacial tension), and power factor. Oil color testing is directly related to particle contamination. As the dielectric oils age you may experience any of the following
    • High replacement costs
    • Disposal costs
    • System failure
    • Service Outages
    • Moisture in oil
    • Contaminants in oil
COMO has standard and custom designed Transformer oil specific equipment that ranges from single filter element Load Tap Changer and on-site transformers to in-plant multi-stage PLC (programmable logic controller) controlled 1 micron particulate filtration with Fullers Earth sequence and post filtration. Batch recycling machines to 3000 gallon process volumes are also part of the mix.
