Reduction of TAN in Fyrquel, desired quality specs

kayeemmonsMember

We use Fyrquel as the hydraulic fluid for our steam turbine, and have been informed by an oil analysis/oil treatment company that the oil needs to be treated or changed out due to higher than desired water content, TAN, and particle levels (ISO). What are the recommended limits for these three parameters?

Our analysis shows water content at 600 ppm, TAN (shown as mg(OH)K?) at 0.38, and ISO cleanliness rating at 16/14/12. This doesn´t seem too back to me, except maybe for the water, but I don´t know.

The company talks about being able to filter, remove water and reduce acid. I´m familiar with the first two, but can they adequately remove the acid compounds? Is this something that a fullers earth filter could take care of? Thanks.
