TAN Analyzer for oils with TAN higher than 7

Read our primer articles on Oil Analysis and Tribology

Dear People

In our facilities in Spain, we are running oil analysis on site. Most of our equipments are steam or gas turbines.

However we are dealing with some reciprocate compressors in a Chemical Plant, where we need to analyze TAN values, and sometimes these values are expected to be higher than 7.

We have a portable TAN analyzer that provide us very good results in 0-6 mg (OH)K.

We would like to know if there is another technology for onsite TAN analysis for results higher than 7.

We wait for your comments.

Thanks in advance,

Schmid,

Are you frequent experiencing the TAN value exceeding 7?

How if we dilute the oil sample with water, and then analyze with PH paper indicator?

Are you concerned about oil oxidation? If so, suggest you look at our Fluitec RULER to measure the antioxidant level in the oil followed up with MPC patch. Please contact me if you need this information.

Nurudin, Eric

Thanks for your replies!

We are also running MPC and Ruler tests.

The idea of running TAN, is to detect the presence of corrosive gasses in the crankase oil of reciprocant compressors. We know that we could detect them by flash point, or other tests, but our customer wants to detect it with TAN Analysis. They know that TAN higher than 7 means that they have to change the oil.

Since you already run RULER for antioxidants, you could also run the TAN with the RULER. Ask Fluitec for their RAN solution. Test will probably use 50 - 100 uL of oil since high TANs are involved.

Schmid,

Frequent experiencing TAN > 7 mg KOH/g, as per my consideration is not only about to change the oil

I think there was something wrong
