Whether for on- or off-shore applicati-ons, whether for the extraction of oil orgas, for refineries, the chemical orpetrochemical industry Klber offersspecial lubricants that are preciselytuned to your needs and the types ofgases in your compressor.

We regard the lubricant as an essentialdesign element of the compressor, justas bearings, rotors or slide valves.More than 80 years of practical experi-ence in research, development andapplication of special lubricants ensurea product quality that increases thereliability, availability and productioncapacity of compressors. These bene-fits enable maximum asset perfor-mance in particular in the oil and gasindustry where the cost of downtimeand machine failure is extremely high.

The outstanding benefit offered byKlber is not only lubrication as such,but also the fact that our lubricants are

precisely tuned to the particular type ofgas stream that is being compressed.Depending on the composition of thegas stream in your process, it candilute the compressor oil. The gasstream may consist of hydrocarbongases like propane, inert gases likenitrogen or aggressive gases likemethyl chloride, all in varying concen-trations. Under pressure, many gasestend to be dissolved in certain lubrica-ting oils and may reduce their viscositysignificantly.

Lubricant additives or base oils mayreact with components of the gas,leading to the formation of sludge anddeposits. Premature wear, extra down-time for maintenance, high oil con-sumption and shorter oil change inter-vals are common consequences.

No matter where your gas compressor operates,

we are specialists for its effective lubrication.

Lubricating oils in rotary screw-typecompressors for process gases fulfilla number of different tasks:

They lubricate the rotors andthe bearings.

They seal the gap betweenrotor and casing, and betweenthe rotors.

They cool the gas stream beingcompressed.

They remove heat.

They protect against corrosion.

An important factor especially for thelubrication of bearings and rotors is theright viscosity of the lubricating oil,

which should under all operating condi-tions comply with the instructions pro-vided by the compressor manufacturer.

If the gas stream did not affect thelubricating oil, the choice of viscositywould be a fairly simple task. But cer-tain gases tend to be dissolved in cer-tain lubricants. This effect may consi-derably reduce the oil's viscosity andprevent the formation of an effectivelubricant film. This may in turn lead toreduced service life or failure of the airend and hence machine downtime.

The composition of the gas streams

to be compressed is as varied as theprocesses for which they are used.The lubricating oil for the compressorshould be chosen just as individually.

1.1. Many compressor shut-downs due to wear?

Viscosity and gas solubility are a decisive factorWith the right lubricating oil you will not only reduce wear and increase the life of individual components as well as that of your machines as a whole, but you willalso boost your operational reliability and hence your profits. But which lubricatingoil will release this potential?

Every gas stream is unique.Klber Lubrication is the only lubricantsupplier to have tailor-developed aprogram to calculate the tendency ofthe individual gases to be dissolved inlubricating oil. All factors determining thistendency are taken into account, inclu-ding the actual operating conditions:

1. Pressure:The higher the compression, thehigher the tendency of the gasto be dissolved in the oil.

2. Temperature:The higher the compressiontemperature, the lower thetendency of the gas to bedissolved in the oil.

3. Molecular weight:The higher the molecular weight

of the gas, the higher its ten-dency to be dissolved in the oil."Heavy" hydrocarbons such astoluene are more easily dissol-ved than "light" ones such asmethane or propane.

4. Polarity:When it comes to polarity, theprinciple of "likeness" applies.Polar gases such as ammoniaare easily dissolved in polar oilssuch as polyglycol, while homo-polar gases such as hydro -carbons are less easily dis -solved in polar oils.

Taking into account these criteria,Klber can calculate the tendencyof your gas to be dissolved in thelubricating oil already before yourrotary screw compressor is filled withlubricant. This gives us valuable infor-mation about the oil's viscosity underactual operating conditions, and wecan suggest a lubricant that will meetthe manufacturer's viscosity require-ments in all real-life situations.

A lubricant with a viscosity that is inline with manufacturer's instructionsinevery stage of compressor operationhelps you to extend your productioncapacity. After all, less compressorwear leads not only to

longer component life and

higher operational and productionreliability throughout your plant

but also to

less production loss due tomaintenance downtime,

a higher degree of compressoravailability and

a better utilization

An example:

The first step is analyzing the gas stream composition:54 % methane CH 4 16 % C 2H10 , C 5H12 , C 6H1416 % hydrogen H 2 36 ppm hydrogen sulfide H 2S16 % ethane C 2H6 16 ppm hydrogen chloride HCI

8 % propane C 3H8

2. The second step is analyzing the operational data of the compressor:

Discharge pressure: 8.5 barDischarge temperature: 95CSuction pressure: 1.2 barSuction temperature: 28COil temperature to the bearings: 65C

3. The third step is the viscosity requirement of the OEM: Application example: oil-injected rotary screw compressor

>12 mm 2 /s at 65C (oil injection temperature to the bearings)> 8 mm 2 /s at 95C (oil injection temperature to the rotors)

4. The fourth step is suggesting a suitable oil for the application:

For this operational data, we would suggest Klber Summit NGSH-150.

We have enclosed a "Technical Questionnaire for Process Gas Compressors",which will help you to quickly and easily compile your application data and sendthem to us so that we can recommend a suitable product. We will also gladlycalculate the lubricating oil viscosity that brings you maximum benefit.

The pitfalls of chemistry:reaction products.When mixing under high pressure andtemperature, gases may not only bedissolved in the oil, they may also reactwith base oils or additives. Conventio-nal mineral oils, in particular, containunsaturated hydrocarbons and sulphurcompounds that tend to react withreactive gas components. Furthermore,base oils and additives may be affec-

ted by acids or humidity contained inthe gas stream. The complex chemicalsystem present in a compressor hostsa vast potential for chemical reactionand polymerization.

A typical consequence of this type ofreaction is the formation of sludge orsolid residues. Both may severely affectthe lubricity of the oil and lead to consi-derable wear on rotors and bearings.

Another possible effect is the cloggingof oil filters and separators, which inturn leads to higher oil consumption.So a high consumption of oil filters andseparators, short oil change intervals,

frequent machine stoppage for mainten-ance, high oil consumption all leadingto substantial costs are inevitable. Ormaybe they arent?

1.2. Problems with residues, deposits

and sludge in the Oil.Chemical compatibility may bethe cause

Reduce your maintenance and operating costs by using compres-sor oils from Klber Lubrication. Hows that possible? Becausewith Klber oils you will need less new oil filters and separators,reduce reaction by-products in the compressor and cut your oilconsumption.

Our reaction:low-reaction lubricants.To avoid the formation of reactionby-products and prevent avoidablecostsfor maintenance and spare parts,Klber Lubrication checks the compa-tibility of gas stream and lubricating oilbefore it is used in a particular com-pressor.

Based on chemical expertise gatheredduring more than 75 years of advancedresearch and development, our team ofexperienced chemists ensure that weknow and understand the possiblereactions between gas and oil compo-nents, and about the conditions underwhich they occur.

With this background, an accurateanalysis of the gas stream being com-pressed enables us to find a suitable

lubricant for your rotary screw com-pressor from our range of more than 25different process gas compressor oils.

This means for you:

less reaction by-products, depositsand sludge

lower filter consumption due toless deposits

lower costs due to longer oilseparator life

lower oil consumption due tolonger oil change intervals andhigh separator performance

less wear on rotors and bearingscaused by reaction by-products(consequent longer rotor and bea-

ring life)

less downtime for normal andextraordinary maintenance stops

to replace oil filters, oil separators,bearings and rotors.

lower operating and maintenancecosts

In brief you will save a lot of inconvenience and costs.

When standard oils beat it. At high compression temperatures, theoil injected into the compressor tendsto evaporate in particular standard-quality mineral oils and is carriedalong with the gas stream. There it ispresent in two forms: as oil vapor andas oil aerosol (small droplets) . Theaerosol is mostly filtered out mechani-cally by the oil separator; the oil vapor,however, can cause problems as itremains in the gas stream, being one

of the causes of continuous oil con-sumption. Consequently, the more oilevaporates, the more is consumed.

In chemical processes where the purityof the gas stream is essential, the pre-sence of oil in the gas is highly undesi-

rable. But a high oil content can alsocause problems in applications in theoil and gas industry. Downstream cata-lysts may suffer damage due to theeffect of certain oils and additives.Components such as heat exchangersor pipes may be clogged by conden-sing oil vapor. In addition, a high oilcontent in the gas stream leads to highoil consumption.

A lot of problems for which

Klber Lubrication offer tailor-madesolutions.

1.3. High oil consumption and high oilcarryover to the gas stream?Low evaporation and carryover fora pure gas stream

Our special lubricants for the compression of inert gases such aspure hydrogen or nitrogen ensure that the gas stream remainspure. After all it's the compressor that needs lubrication, and notthe gas stream.

Klber Summit: synthetic pro-blem solvers.With our Klber Summit oils we offeryou an extremely wide choice of fullyand semi-synthetic products for alltypes of compression processes. Thehigh resistance to evaporation of theseoils comes into play in particular attemperatures above 70C, which ensu-res that the amount of oil vapor carriedalong in the gas stream is kept to aminimum.

Furthermore, several of our oils havebeen approved by a leading manufac-turer of catalysts in the oil and gasproducing sector: UOP. ConsequentlyKlber Lubrication can supply the idealoil for every application.

This means for the compression process:

Highly reliable processes, especi-ally chemical ones

Less oil carryover, continuouslyhigh efficiency and long service lifeof catalysts and downstream com-ponents

Less stoppage for cleaning (heat exchanger) and replacement ofcontaminated components

This means for you:

Purity requirements are met.

Oil consumption is lower (refill quantities).

Downstream components livelonger.

Need for maintenance as is causedby oil in the gas that makescleaning of the contaminated com-ponents necessary is reduced.

Maintenance and operating costsare reduced and the availability ofyour compressor increased.

hydrocarbon gases, which are used topower several gas turbines. When thecompressor is down, the gas turbinescannot be used, and the gases mustbe flared off.

After seven years of numerous break-downs, bearing damage and produc-tion downtime, the operator contactedKlber Lubrication. Following a detai-led analysis of the gas stream, a spe-cial gas compressor oil was suggestedfor this application. Use of the new oil Klber Summit PGS 100 startedwhen the defective compressor hadbeen replaced.

Regular used-oil analyses.If you wish to accurately time oil main-tenance stoppage and avoid additionaldowntime, you should have the oil inuse inspected on a regular basis. As thegas composition in a compressor isnever the same, any prediction ofcompressor oil life is a rough estimate.Oils may age faster or live longer thanex pected. It is therefore advisable toregularly analyze the compressor oilbeing used.

Depending on the types of gases, ope-rating conditions and compressor run-time, we will define sampling intervalstogether with you. We will provide youwith standardized sample bottles, whichyou fill and send to our lab at the spe-cified intervals. A few days later, youwill receive a comprehensive lab reportinforming you about the conditions ofyour oil and any steps to be taken.

This measure will help to preventmachine downtime, reduce mainten-ance costs and increase compressoravailability.

You can find us where you need us.Having addresses to contact on everycontinent and more than 1,400 staffworldwide, we are never far awayfrom you.
