Abstract
The 14 MeV Neutron Activation Analysis (NAA) spectrometry at KFUPM was used to study degradation of two types of turbine oils while in service in steam-turbine compressors operating in parallel at a local plant. The study was carried out to track total oxygen content of the oils and to compare total oxygen with other condition monitoring tests over a one-year service span. Total oxygen content was measured in both new and used oil samples. The results of 14 MeV NAA were compared with those of the RBOT and relative oxidation methods, which measure oxidation resistance in turbine oils and the concentration of oxidation products, respectively. Total oxygen as determined by NAA was found to bear a linear relationship with relative oxidation and a logarithmic relationship with RBOT.
