Phosphate Ester Varnishing
Unique aspects, testing and maintenance
→Why Varnish Removal Fails
The Soluble-Insoluble Turbine Lubricant Varnish Equilibrium Turbine lubricant varnish is produced by breakdown of hydrocarbon lubricants. Its deleterious impact on equipment performance and reliability is well-documented. Varnish has traditionally been defined as an
→Oil and Water Shouldn’t Mix
Restoration of Steam Turbine Oil Demulsibility Steam turbines are responsible for up to 80% of global electricity production. Because steam powers these units, ingression of water into steam turbine oils is a common
→What Routine EHC Fluid Testing Fails to Detect
Improved EHC Fluid Maintenance through Non-routine Testing Despite the critical nature of electro-hydraulic control (EHC) systems, many steam turbine operators’ EHC fluid testing programs fail to detect fine insoluble contaminants that are responsible
→A Paradigm Shift in Gas Turbine Lubricant Management
Treat your gas turbine lubricant as an asset. While gas turbine lubricant management is recognized as being essential, many programs lack the basic tools to maintain their lubricants within specification. Existing gas turbine lubricant

→Varnish Mitigation: Relative Effectiveness of Non-Deposit-Forming Next Generation Lubricants vs. the Use of Varnish Removal Filters with their Conventional Counterparts
Matthew G. Hobbs, PhD, Peter T. Dufresne Jr. Paper Abstract Turbine lubricants employ a variety of base fluids. Mineral oil-derived base stocks remain the most prevalent, however, synthetics are becoming increasingly common. These
