The oil was last changed in 2003 and the RULER tests started in 16/7/2007 when we notice a drop in RPVOT=107 or 34%
It's a steam turbine, and the oil contains 85 ppm of zinc when new.
New oil is very light in colour like straw (not green.
Demulsibility new=41-37-2(20)current=40-40-0 (30)
Foam
-sequence I =300-0 current=440-5
-sequence II =10-0 current=30-0
-sequence III=70-20 current=480-10
Are you saying that the amine is removed by the Kleentek oil cleaner?
