Item type:Publication, Varnish and Sludge Potential: Strategies for Successful Gas Turbine Oil Condition Monitoring(2023-01-01); One growing concern in power plants nowadays is the presence of one of the lubricant degradation by-products that can affect the lubrication system, which is sludge and varnish. Membrane patch colorimetry (MPC) was performed to determine both soluble and insoluble varnish in used lubricating oil. The varnish potential index (SI-MPC) is the new guideline to evaluate the overall varnish and sludge formation, and it helps in detecting early signs of possible varnish and sludge problems in the system. Viscosity, FTIR, linear sweep voltammetry (LSV), total acid number, and particle count were also performed to monitor the correlation between varnish and sludge formation. The result shows that the early detection of soluble varnish (S-MPC, ΔE 13.0) before it transforms to insoluble varnish can help the power plant make an action plan before the varnish problem becomes worse (I-MPC, ΔE 68.5), and an increase in the varnish potential index also relates to the depletion of antioxidant additive (50.8%) and increased particle count (ISO 21/17/14) of the lubricant. Thus, proper monitoring of soluble varnish (S-MPC), insoluble varnish (I-MPC), and varnish potential index (SI-MPC) can improve the diagnostic and corrective actions for varnish problems in gas turbines. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Production of empty palm bunch biochar using microwave-assisted pyrolysis at low temperature(2021-09-15); In this study, the production of palm empty fruit bunch biochar using microwave-assisted pyrolysis at low temperature was investigated. The empty palm bunch composition was analyzed by proximate analysis. The parameters relating to the production, i.e. type of microwave absorber, microwave power, heating time and ratio of palm empty fruit bunch to initial amount of microwave absorber, were studied to determine the optimum condition. The results found that the amount of fixed carbon in the empty palm bunch was approximately 10%. The optimum condition was microwave power 300-watt, heating 450 sec and ratio of empty palm bunch to concentrated sulfuric acid (the most suitable microwave absorber) 1:2.5. At this condition, the production yield was 50.78%. The iodine number of the biochar was 318.5 mg/g. The BET surface area of the biochar was 101.54 m2/g. The total pore volumes and pore diameter of the biochar were 0.144 cm3/g and 4.29 nm. respectively. The elemental analysis of biochar at the optimum condition was mainly composed of carbon and oxygen. The ratio of O/C is 0.73 indicating that the biochar is quite stable product against oxidation. - Some of the metrics are blocked by yourconsent settings
