Problem
Following a scheduled shutdown, the lube oil system of a gas turbine exhibited an escalating pressure differential across filter inserts. Subsequent oil analysis revealed a rapid increase in MPC levels, reaching up to 44, accompanied by the emergence of varnish deposits in the system.
Solution
Fluitec’s partners assessed the existing conditions and decided to add DECON™ at a treat rate of 3%. This should decontaminate the system and aid in reducing the constantly increasing differential pressures.
Results
Following the addition of DECON, MPC levels have consistently remained below 10. Simultaneously, the previously increasing filter differential pressures were stabilized. Other essential oil properties, including viscosity, oxidation stability, foaming tendency, and air release, remained within acceptable parameters. This facilitated prolonged utilization of the turbine oil, eliminating the need for a flush and recharge operation.
