Book Synopsis Oxidation Testing of Long-Life Turbine Oil Fluids. Can We Do Better? by : DE. Chasan
Download or read book Oxidation Testing of Long-Life Turbine Oil Fluids. Can We Do Better? written by DE. Chasan and published by . This book was released on 2006 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four turbine oils formulated with varying types and concentrations of antioxidants were aged via D 943 exposure and examined extensively at 1000, 2000, 5000, and 10 000 h. Acid number, Rotary Pressure Vessel Oxidation Test (RPVOT), High Pressure Differential Scanning Calorimetry (HPDSC)RP, and sludge determinations were made at each time interval. Only a combined evaluation of the test results for the 10 000 h oil samples (a "Total Oxidation Products" approach) gave a reasonable estimation of the true oxidative state of the fluids. One shorter term test, ASTM D 6514, was found to give a fair prediction of the overall quality of the fluids at 10 000 h.

Book Synopsis Physical, Performance, and Chemical Changes in Turbine Oils from Oxidation by : Brian T. Thompson
Download or read book Physical, Performance, and Chemical Changes in Turbine Oils from Oxidation written by Brian T. Thompson and published by . This book was released on 2007 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the primary factors in determining the life and performance of turbine oils is its oxidation stability. Oxidation can cause a host of problems for in-service turbine oils, such as sludge, deposits, lacquer, and varnish formation. There is limited published research on the performance of turbine oils once oxidation begins. This paper presents data on the relationship between several turbine oil characteristics during the oxidation process by focusing on the measurable physical and chemical changes that occur. Five turbine oils were chosen, each employing different antioxidants and base oil refining technologies to represent a typical selection of commercially available turbine oils. A 49-day experiment was completed in which the oils were subjected to a controlled and accelerated oxidative process under laboratory conditions. Throughout the testing period, samples were drawn and a range of chemical, physical, and performance tests were performed. The data obtained from this experiment identify several correlations that relate to the performance of each oil. These data are useful in understanding the relationship between turbine oil oxidation and fluid performance and will help end-users in selecting and optimizing their turbine lubricant.

Book Synopsis Evaluation and Comparison Between Oxidation Stability Test Methods for Turbine Oils by : M. Pach
Download or read book Evaluation and Comparison Between Oxidation Stability Test Methods for Turbine Oils written by M. Pach and published by . This book was released on 2006 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, long established oxidation tests such as TOST (ASTM D 943-03) and RPVOT (ASTM D 2272-02) in combination with the acid number (ASTM D 974-03) test has been used to screen the oxidation stability of turbine oils. Lately, nevertheless, a new voltammetric method has been applied to measure the remaining useful life (RUL) of turbine oils, RULERTM (ASTM D 6971-03) as it uses microlitre amounts of sample and needs only a short testing time. The aim of this study is to examine the correlation between the RULERTM voltammetric test in comparison to the standing oxidation turbine methods, TOST and RPVOT. Three fully formulated commercially available oils were studied; two were based on synthetic esters and one was mineral oil based. In addition, other oils were tested in our laboratories in Norway and Sweden in order to investigate the correlation between RULERTM and RPVOT oxidation stability tests. Field samples were also used to evaluate those methods. Although those studies have been worthwhile, reaching a definite conclusion regarding correlations has proven to be somewhat difficult. It is clear, however, that by a careful methodology, a useful correlation for the investigated oil types may be obtained. For example, guide limits for RULERTM results and their correlation to RPVOT values were established.

Book Synopsis Oxidation Fundamentals and Its Application to Turbine Oil Testing by : VJ. Gatto
Download or read book Oxidation Fundamentals and Its Application to Turbine Oil Testing written by VJ. Gatto and published by . This book was released on 2006 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current turbine oil oxidation bench tests have been in place for many years. Recently, however, the basestocks used to formulate these lubricants have changed significantly. Traditional basestocks, containing high levels of aromatics and sulfur, have been substantially displaced by more highly refined basestocks, which have very low levels of aromatics and almost no sulfur. Over time it has become clear that the oxidation performance of the different basestock classes is quite different. One key question, however, remains unanswered. "What modifications are required in current bench tests to adequately mimic oxidation processes in modern turbine lubricants?" In order to adequately address this critical question, the fundamentals of lubricant oxidation and stabilization will be discussed. Data will be presented on the oxidation of different basestocks under varying conditions of temperature, metal catalysts and antioxidant type, using model bulk oil oxidation tests. The data highlights the fundamental oxidation mechanisms that can occur in turbine oil systems and new test methods are proposed.

Available in PDF, EPUB and Kindle. Book excerpt: Plant engineers are responsible for a wide range of industrial activities, and may work in any industry. This means that breadth of knowledge required by such professionals is so wide that previous books addressing plant engineering have either been limited to only certain subjects or cursory in their treatment of topics. The Plant Engineering Handbook offers comprehensive coverage of an enormous range of subjects which are of vital interest to the plant engineer and anyone connected with industrial operations or maintenance.This handbook is packed with indispensable information, from defining just what a Plant Engineer actually does, through selection of a suitable site for a factory and provision of basic facilities (including boilers, electrical systems, water, HVAC systems, pumping systems and floors and finishes) to issues such as lubrication, corrosion, energy conservation, maintenance and materials handling as well as environmental considerations, insurance matters and financial concerns. One of the major features of this volume is its comprehensive treatment of the maintenance management function; in addition to chapters which outline the operation of the various plant equipment there is specialist advice on how to get the most out of that equipment and its operators. This will enable the reader to reap the rewards of more efficient operations, more effective employee contributions and in turn more profitable performance from the plant and the business to which it contributes.The Editor, Keith Mobley and the team of expert contributors, have practiced at the highest levels in leading corporations across the USA, Europe and the rest of the world. Produced in association with Plant Engineering magazine, this book will be a source of information for plant engineers in any industry worldwide.* A Flagship reference work for the Plant Engineering series* Provides comprehensive coverage on an enormous range of subjects vital to plant and industrial engineer* Includes an international perspective including dual units and regulations
