Six Steps For More Effective Oil Analysis

Whether you currently have an oil analysis program in place, or are putting one together, it is imperative to ensure that equipment is properly sampled to meet the goals of a specific maintenance program. To provide the program with the proper foundation, six basic questions must be asked: What do you want to get from your oil analysis program? What units need to be sampled? Where does the sample need to be taken on the equipment? How are the samples going to be procured? How often do samples need to be taken? What tests are needed? Some of these steps can be performed simultaneously, while others must be done in sequence. Step 1: The Functions of an Oil Analysis Program This first step is critical. It provides the direction for nearly all future decisions regarding the oil analysis program. Can failures be caught early? Are there lube-mixing problems that need to be prevented or caught before resulting issues occur? Or does the lubricant health simply need t...

Estimating Turbine Oil Oxidation

From steam turbine to gas turbine, from power generation to refining, turbines are pervasive throughout industry. While turbine systems can endure a whole host of different failure modes, studies by major turbine manufacturers such as General Electric have pointed to the lubricant as one cause of poor reliability. However, other factors such as maintenance and operational practices, electrostatic discharge, contamination, and lubricant chemistry have been identified as root causes. Turbine oils must endure a host of different challenges due to heat from the process itself, compressive heating, aeration, and internal and external contamination, including water and particles. Perhaps the most misunderstood failure modes are those induced by the turbine oil itself. While turbine oils are naturally pure, well-formulated oils, the long-term stress caused by adverse operating conditions can result in both thermal and oxidative degradation of the oil which can cause problems with t...
