OilDoc Symposium – Lecture topics
Language of presentation: German
Hot varnish – deposits despite low MPC value – detection and remediation methods
Find out why harmful varnish deposits can form despite low MPC values and why they are often detected too late. Tried-and-tested diagnostic procedures are presented, along with effective measures for preventing and removing varnish in oil and lubricant systems.
Dipl.-Ing. Rüdiger Krethe
General manager OilDoc GmbH
Shear stress-induced deposition mechanisms in ultra-thin oil films – background information and remedial measures
Based on the stresses in ultra-thin oil films, it is shown how high shear stress leads to previously underestimated deposition mechanisms. Based on physical principles and practical examples, influencing factors, typical damage patterns, and effective measures for preventing and removing these deposits are presented.
Jo Ameye
General Manager, Fluitec NV
Oxidative and thermal stability – Turbine oil specifications for modern gas turbines
The focus is on the requirements of modern gas turbines in terms of the oxidative and thermal stability of turbine oils. Current specifications and test procedures are used to demonstrate how suitable oils can be selected and how oil aging, deposits, and failures in turbine operation can be reliably minimized.
Dr. Ludger Quick
Consultant, Dr. Quick Schmierstoffberatung
(formerly Siemens Energy)
Use, handling, and monitoring of turbine oils from a sustainability perspective
The presentation highlights the use, handling, and monitoring of turbine oils in the context of sustainability. This highlights fundamental aspects of resource-efficient and responsible oil management.
Thomas Bergmann
Senior Lubes Field Engineer, ExxonMobil
Varnish detection using MPC in phosphoric acid esters
This presentation will highlight the special features and limitations of varnish detection using MPC in phosphoric acid esters. This includes typical sources of error, the interpretation of measurement results, and supplementary diagnostic methods for the reliable assessment of deposit risks in fire-resistant fluids.
Carsten Heine
Technical Support Manager, OELCHECK GmbH
