I was watching this video that in my first experience on Varnish in PDO in Oman that I was a SKF Lubrication consultant there , Peter Dufresne EPT Clean Oil presented to us. Why “Keeping Varnish Dissolved” with Aftermarket Chemistry Can Become a Reliability Risk The problem is not varnish color. The problem is varnishContinueContinue reading “Why “Keeping Varnish Dissolved” with Aftermarket Chemistry Can Become a Reliability Risk”

End-of-Life Management of Used Turbine Oil: Technical Practices, Recycling Routes, and Disposal Cost Drivers Abstract Used turbine oil is a high-value industrial lubricant, not a simple waste stream. In power plants, petrochemical facilities, refineries, wind farms, marine systems, and large industrial sites, turbine oil is managed through a full life-cycle process: condition monitoring, purification, regeneration,ContinueContinue reading “End-of-Life Management of Used Turbine Oil: Technical Practices, Recycling Routes, and Disposal Cost Drivers”

Turbomachinery bearing vibration and turbine-oil varnishing: a technical article 1. Core answer The main vibration families seen at turbomachinery bearings are radial/lateral vibration, axial/thrust vibration, torsional vibration, casing/structural vibration, and frequency-domain classes such as synchronous 1× vibration, harmonic vibration, subsynchronous vibration, oil whirl, oil whip, rub-related vibration, broadband/random vibration, and, in machines with rolling-element bearings, bearing defect-frequency vibration. For varnishing, the most important conclusion is this: VarnishContinueContinue reading “Turbomachinery bearing vibration and turbine-oil varnishing: a technical article”

Wishing It Was That Easy: Why MPC Varnish Potential Does Not Directly Equal Bearing Varnish Deposits It would be convenient if varnish behavior were simple: MPC 5 equals clean bearings, MPC 30 equals moderate amber staining, and MPC 60 equals heavy black varnish. That kind of image is useful for communication, because it shows theContinueContinue reading “Wishing It Was That Easy: Why MPC Varnish Potential Does Not Directly Equal Bearing Varnish Deposits”

Can varnish layers trap particles on mechanical surfaces? Yes. A varnish layer can trap particles, especially dirt, wear metal, soot, oxidation products, fibers, and degraded additive residues. But it does not work exactly like a designed mechanical filter. A filter is engineered with controlled pores, flow paths, and dirt-holding capacity. Varnish is an unwanted, uneven, sticky or hardenedContinueContinue reading “Can varnish layers trap particles on mechanical surfaces?”

Oxidation Testing in Turbine Oils: TOST, Dry TOST, RPVOT, History, Meaning, and Practical Interpretation 1. Introduction Oxidation is one of the main ageing mechanisms in turbine oils. In service, turbine oils are exposed to heat, oxygen, catalytic metals, entrained air, water, and long residence times. As oxidation progresses, the oil can form acids, sludge, varnishContinueContinue reading “Oxidation Testing in Turbine Oils: TOST, Dry TOST, RPVOT, History, Meaning, and Practical Interpretation”

Rapid Turbine Oil Handling Practice Assessment for Every Site Khash Visits 1. Purpose of the site visit When Khash visits a power generation, refinery, compressor-drive, or industrial turbine site, the goal is not only to “check the oil.” The goal is to determine whether the site’s turbine oil handling system can consistently prevent contamination, degradation, wrong-oil addition,ContinueContinue reading “Turbine Oil Handling Practice Assessment”
