SVR Reduces MPC From 60 to 6 in 45 Days

A peaking power plant was concerned about unit trip or fail-to-start conditions as one of the GE 7FA turbines had critically high varnish potential QSA® 100 (MPC ΔE ~60).  The phenol anti-oxidant additives were also at a critically low level of ~4% of new oil level.  Maintenance had also noticed that the main lube, pump discharge and actuator filter elements were coated with varnish deposits when changed so they were being changed quarterly instead of annually.  varnished element

The contamination challenge was to remove the varnish deposits suspected throughout the lube and hydraulic systems that were supplied with oil from a common reservoir for both systems (common GE 7FA design). With phenol anti-oxidant additive levels extremely low the propensity for deposits to form was very high.
