I saw an older post that discusses Fyrquel contaminated with lube oil, currently my lab results say that i have a 2% contamination level in my EHC fluid. I am performing feed and bleed, but the real question is, does anyone know if it is possible to separate or clean the non-saponifiables out of the EHC Fluid? we believe we know where the contamination is occuring however we cannot shut down until 2014 to make the repair. Our contamination rate is ~1 gallon per day into 4000 gallon EHC System.
4000 gallon EHC reservoir? That must be one big unit. What's that on? I take it that this EHC is for a steam turbine control and stop valves.Never saw that occur in lots of years in mechanical maintenance on GE machines[Craig Generating Station Craig,Colorado]. Where do you think the turbine oil is getting into the EHC unit? I can't think of any cross-connection at all on our units. Any supplemental filtration equipment being used? What does Stauffer,Akzo,ICL whatever say? I know this post is dated, but I just recently started to look at Noria's sight.Still interested after sixteen years into retirement. Regards
