standard for oil condition monitoring

Dear Aziz,

First you need to take a survey of critical oil wetted parts in your plant and then categorize those equipment as per type of equipment/Application(Ex. Gear box, turbine, Hydraulic system, Compressors , Engine Etc.). Design a Oil analysis test slate (Different equipment needs different oil tests and 70-75% tests are common for all equipment). Oil condition( Visual, Color, Visc @40degc -standard, Visc@100degc-optional, VI-optional, % Moisture- Standard, AN( Total acid Number)- Standard, Foaming characteristics- Optional based on application, Demulsibility- Optional, RBOT/RPOVT- optional for oxidation, Patch colirometri( Varnish potential)- For turbines. )) Machine wear- Elemental analysis- Spectroscopy- ICP is standard, Ferrography(DR Ferrography- Analytical ferrography)-Optional, FTIR- standard for engines and optional for othes, Contamination- Particle counting or patch test- standard. Most of these tests are ASTM standard. Establish a frequency. Most critical 1M to 3M(mostly 3M) & Less critical (3M to 6M). if you want to establish a lab of your own purchase start with basic instruments or else optional is contact Oil analysis service provider with ISO-17025 accreditation .Now a days oil suppliers also provide oil testing as a complimentary.(Some people have reservations about the conflict of interest).

thanks in advance prdip .

Aziz offers some good advice. If you are using a commercial lab they can lend their expertize to your endeavor. Most have standard test slates that cover the different tests depending on the type of equipment. Your lubricant supplier is also a good source of knowledge and experience especially the major suppliers. If money is not an issue (?) the best way to get an effective program started is to have an expert come in and do a survey and setup the program for you. This eliminates quite a few of the growing pains and wasted time, money and effort. I feel if your lubrication program is big enough it is money well spent.

dear all

i am looking for standard guide to establish oil condition monitoring group in our oil and gas refinery .

any help will be appreciated 

thanks 

Hi Aziz,

You can use the following standard:

- API 614 for your lube oil system

- ASTM D4378, for lubrication condition monitoring of your Turbines

- ASTM D6224, for the other various rotating equipment.

Good luck,
