Solutions to improve air qualityGuidance on the treatment of compressed air

Compressed air is used today in diverseindustrial sectors. The multitude of appli-cations range from untreated blow-downair to absolutely dry, oil-free and sterilecompressed air for the pharmaceutical andfood industry. This rich spectrum of appli-cations demands individual levels of com-pressed air treatment, designed preciselyfor each application.

1 m3 of compressor intake air can containup to 180 million particles of dirt. Besidesthese particles of dirt, the intake air canalso contain 50 – 80% water vapour andoil in the form of unburnt hydrocarbonsfrom machinery and waste gases. In addi-tion, tiny amounts of lubricating oil anddust from the compressor can get into thecompressed air network. When compres-sed to 10 bar for example, the concentra-tion of these harmful substances increaseseleven-fold, i. e. 1 m3 of compressed aircan contains up to 2 billion particles of dirt.Depending on the application, these par-ticles of dirt will have to be removed untilthe compressed air becomes absolutelydry, oil-free and sterile.

The table on page 3 gives a summary oflevels of achievable air quality. However, itcan only show an overview of the possibili-ties. When choosing a treatment system,the starting point must be to accuratelydetermine the use of the air – the applica-tion. This establishes the required qualityfor the compressed air.

Compressed air treatment requires:

additional investment cost

maintenance work on treatmentsystems

But correct compressed air treatment:

increases the service life of compressedair operated equipment

improves the quality of your products

increases your competitiveness

increases your company’s profitability

reduces the risk of operating problems

reduces repair costs for compressed airoperated equipment

reduces purchasing costs for pipingsystems

At the planning stage, the experiencedBOGE team can advise you about the typeof compressed air treatment most suitedfor your application. This support protectsyou from installing a higher – or lower –level of air treatment equipment than ne-cessary. BOGE can provide you with theoptimum solution for your application, bothfrom the point of view of cost and quality.

The advantages of usinga BOGE refrigerant dryer

Refrigerant DryersOne of the most economic methods oftreating compressed air is with a refrigerantdryer. By cooling the compressed air downto near freezing point, the water and oilvapour are condensed and particles of dirtare bound together, the resulting conden-sate is then separated from the air flow.

In many cases, the pressure dewpointneed only be a few degrees lower than the ambient temperature to preventcondensate from forming in the pipes.

Recycling and Waste DisposalRecycling and waste disposal aregrowing problems around the world.Therefore, a recycling list is attached insidethe machine housing, defining exactlywhich materials have been used.

Reduced quantityof refrigerantR 134a is the standard refrigerant usedthroughout the whole DB and D range.Unlike more traditional refrigerant dryers,the quantity required has been reducedconsiderably by up to 70%.

Environmentallyfriendly BOGE refrigerationtechnologyAnyone involved in refrigeration technology,has a special responsibility. That is whywhen designing the DB and D series, rightfrom the outset, a great deal of importancewas attached to the environmentally friend-ly manufacture, operation and final waste-disposal of our refrigerant dryers.

Heatless adsorption dryers withpressure dewpoints down to –70 °Care suitable when D series refrigerantdryers with pressure dewpoints of+ 3 to +7 °C will not meet the require-ment.

Before drying, the standard BOGE FP-series micro-filter removes any solid andliquid impurities up to 0.01 mm from thecompressed air supply.In the adsorption dryer, the desiccantmaterial adsorbs moisture from the air,resulting in clean, dry compressed air.Pressure dewpoints down to –40 °C canbe achieved with the standard model.

In parallel with moisture adsorption, rege-neration takes place in a second vessel.With type DAZ heatless adsorption dryers,compressed air which has already beendried is used to regenerate the desiccant.

BOGE DAV Adsorption Dryerexternally heated regeneration and vacuum purging, complete with pre-filter and after-filter

Flow capacity: 420 – 14500 m3/h, 247 – 8526 cfmMax. operating pressure: 10 bar, 150 psig

Before drying, the standard BOGE F-seriesmicro-filter removes any solid and liquidimpurities up to 0.01 mm from the com-pressed air supply.In the adsorption dryer, the desiccant mate-rial adsorbs moisture from the air, resultingin clean, dry compressed air. Pressuredewpoints down to –40 °C can be achievedwith the standard model.

In parallel with moisture adsorption, rege-neration is carried out in a second vessel.With DAV series vacuum regeneration ad-sorption dryers, ambient air is drawn intothe package, heated and then used to re-generate the desiccant.

The advantages of using theBOGE DAV Adsorption Dryer

Low-energy systemsavings of up to 25 % compared withconventional systems2-stage dryingfilled with waterproof and fast-actingdesiccant

Active heat in vacuum areadue to physically restricted humidity at 98 °C.Low regeneration temperaturethe drying tower is under vacuum conditionsthereby efficient removal of moisture takesplace at a lower temperature.Intensive coolingthe vacuum lowers the point where moisture‘flashes off’ to atmosphere.Pressure equalisation on wet sidePurge air is only used to equalize pressure.Consistent pressure dewpointas the purge air is fed through the dryer’s inlet.Vessel changeover with no pressuredewpoint peaksas the humidity of the purge air does notreach the dry areas of the desiccant.Pressure dewpoints down to – 70 °Ccan also be achieved, as well as thestandard – 25 °C or – 40 °C.Function messagesfor pressure, temperature, heater operation,vacuum pump and changeover.Alternative energyfor regeneration using steam or hot water(+ others) is available as an option.Modular System OptionsPurge air bypass, thyrister control-heaters,frequency control – vacuum pump.

Activated carbon adsorbers are recom-mended for installation downstream ofcompressed air dryers with filters, inorder to reduce the residual oil contentof the compressed air to 0.003 mg/m3.

Even after filtering out solid and liquid con-taminants up to 0.01 µm, and installing acompressed air dryer, compressed air canstill contain oil vapour.Oil vapour can be passed by the compres-sor or be drawn in from the atmosphere.Oil contamination can depend on the typeof oil and the temperature of operation.

The BOGE DC activated carbon adsorberis used wherever there is the requirementfor the highest quality compressed air. Thecompressed air flows from top to bottomof the adsorber vessel, through a bed ofspecial activated carbon. Optimal contacttime, air flow-rate, bed depth and thequality of the activated carbon ensurehigh-quality compressed air.

The advantages of usingthe BOGE DC activatedcarbon adsorberLarge volume of activated carbon

high quality compressed air due to a residual oil content of only 0.003 mg/m3

Optimum technical designhigh-quality compressed air

Condition of the ambient air

Besides nitrogen and oxygen, the ambientair also contains impurities and moisture inthe form of water (aerosols) or watervapour (relative humidity).

Impurities in the ambient airDepending on the location, ambient aircontains various impurities which cannotbe seen by the naked eye. They can impairthe reliability of compressed air equipmentand furthermore, they can reduce thequality of products produced using thecompressed air.

Behaviour of impuritiesduring compressionWhen air is compressed, the concentrationof impurities increases.

The impurities and moisture drawn in fromthe atmosphere is precipitated as conden-sate in the compressed air installation;depending on the concentration of itsconstituents, it can be oily, greasy and/oraggressive.

Condensate precipitated inthe compressed air systemImpurities from the compressed air systemare washed out in the form of condensate.

Condensate precipitatedfrom the compressed airThe amount of condensate in compressedair depends on the humidity of the intakeair, the temperature and the volume of air.

Condensate precipitates in different amo-unts at different places in a compressed airinstallation and in the compressed air pipenetwork.

Condensate forms when the temperature ofthe compressed air falls below the pressuredewpoint. The pressure dewpoint is thetemperature at which the compressed aircan be cooled without condensate precipi-tating. In our example of a compressed airinstallation, condensate precipitates in thecompressor after-cooler, in the compressedair receiver, in the refrigerant dryer andadsorption dryer. Condensate can alsoprecipitate in the downstream air-line if thecompressed air cools much below thepressure dewpoint, –40 °C in our example.

The condensate from oil-lubricated com-pressors consists of impurities and mois-ture drawn in from the atmosphere, as wellas oil particles in the form of aerosols andvapours from the oil lubrication system ofthe compressor.

Only proper condensate separation,drainage, removal and treatment willensure, environmentally friendly operation.

Mechanical condensatefloat drainsFloat drains have to be sized specificallyto match the calculated volume of conden-sate.

The advantage of a float drain is that it onlyopens when condensate actually accumu-lates. In this way, there is no loss of com-pressed air.

Float drains are maintenance-intensive.Problems can occur due to dirty, greasy orsolid condensate.

Electrical solenoidcondensate drainsElectrical solenoid drains are less mainte-nance-intensive than float drains. The largeinternal cross-section ensures that thecondensate is drained away without re-striction, even with viscous condensates.They can be used for all applications,thanks to step-by-step adjustment of thedischarge time and interval.

The advantage of time-controlled solenoidsis their great adaptability for summer andwinter running and for different sizes ofmachine.

Condensate precipitation is variable.Whilst float drains only discharge whencondensate is present, the solenoid alwaysopens at pre-set times. This means thatwhen there is little condensate, expensivelyproduced compressed air is constantlybeing blown away. The noise of this canbe detrimental to the environment.

Electronic level-controlledcondensate drains;the ultimate solutionCapacity controlled drainage without com-pressed air loss, working automaticallywith the actual condensate precipitated.The large cross-section drain ports ensuresafe drainage of even the dirtiest of con-densates.

Special intelligent control-electronics con-trol drainage. They also monitorthe statusof the equipment. Faults on the drain unitare notified by LED and can be forwardedto a central monitoring point via a potenti-al-free contact.

Condensate treatment and removal

Why does condensate fromoil-lubricated compressorsneed to be treated?Unless condensate is treated of removedcompletely, then serious environmental da-mage can occur. Only 1 Litre of condensateis required to contaminate 1.000.000 Litresof water !

All industrial nations now forbid the drainageof condensate from oil-lubricated compres-sors into main drains. Laws now cover theseparation of condensate into oil and waterand only allow water to be drained away.

In oil-free compressors, the compressed airdoes not come into contact with oil. There-fore, it follows that the condensate has nocontact with oil. Clearly, any traces of oildrawn in are also found in the condensate;the amount depends on the compressor’slocation.

Types of condensateCondensate from oil-lubricated compressorscan occur in the form of:

emulsionsdispersed mixtures

An analysis of the condensate will determinethe scope of separation required. Can asimple oil/water separator be used orshould an expensive separation or filtrationsystem be used, or does the condensatecollected require the services of a specialistcompany?

EmulsionsEmulsions (milky mixtures) form a bond ofoil and water which cannot be separated bygravity. Emulsions can only be purified usingexpensive and costly emulsion separatingequipment.

Dispersed mixturesUnlike emulsions, dispersed mixtures canbe purified by gravity, using relatively inex-pensive oil/water separators.

Condensate testThere is a simple test to determine whetherthe condensate is an emulsion or a disper-sed mixture.

Fill a clean glass with condensate. Stir theliquid and after a short time, the oil separa-tes from the water. The oil floats to thesurface. The remaining water is clear. Thedispersed mixture can be separated out,using an oil/water separator.

If, after stirring, the condensate forms ascloudy water under the layer of oil, then youcan assume that it is an emulsion whichcan only be separated out using an emul-sion separating unit.

Condensate treatmentoptionsDepending on national regulations and theoperator’s environmental policy, the con-densate from oil-lubricated compressorsmust be treated before it is disposed ofinto the main drain system. There are twopossibilities:

1. Collect the condensate and have itremoved by a specialist company;this is generally very expensive.

2. Treat it directly on site.

As the condensate consists of 99% waterand only 1% oil, “on-site treatment” usingthe BOGE oil/water separator is the mosteconomic solution.
