    Eco-Friendly Bio-Lubricant Production from Waste Vegetable Oil and Its Application in Power Plant
    (October University for Modern Sciences and Arts, 2020) Abd-Alla Gad Abd-Alla, Tasneem
    Depletion of petroleum resources and environmental concern, has increased the demand for vegetable oil-based natural esters. In Egypt, it was reported that consumption of lubricants reached 760.025 barrels per day. “Eco-friendly” biodegradable waste vegetable oils can be used as an alternative for petroleum based lubricant that can be applied at power plant. Natural ester insulating (NEI) oils are promising substitutes for mineral insulating (MI) oils because these oils reduce aging of insulating papers in high-voltage oil-immersed power transformers. This work aimed to present the preparation of NEI oil by the esterification process of waste vegetable oil, in addition to comparing chemical, physical and electrical properties for the produced NEI from esterified waste cooking oil and MI oil.
