Power Generation

A large natural-gas-fired combined-cycle power station operating multiple Siemens gas turbines faced rising operational risk due to oil degradation and varnish buildup. Oil analysis showed valve issues, filter blockages, and elevated varnish levels within the turbine loop systems, increasing the risk of unplanned downtime and threatening contractual energy supply commitments. Existing filtration systems failed to fully control contamination.  

A power generation facility operating a GT26 gas turbine experienced persistent lubrication issues caused by severe varnish formation. Oil analysis showed critically high MPC values, indicating a high risk of varnish-related failures, reduced heat exchanger efficiency, filter blockages, accelerated component wear, and compromised turbine reliability. Previous filtration approaches failed to control varnish levels or stabilise oil condition.
