    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Marybeth Chetachukwu Ugoh; [2023]
    Keywords : Base oil; Ageing; Glycerol; PPG; PEG; Squalene; Rapeseed oil; Ester; Paraffin; Oxidation; FTIR;

    Abstract : Environmentally friendly lubricants are in demand in response to the rising concerns and restrictive legislation that surround the use of mineral oil lubricants. One area of importance is understanding the service life of the environmentally friendly base oils of these non-toxic, biodegradable and renewable alternatives. READ MORE

  3. 2. Bio versus Mineral Hydraulic Oil in Forklifts : Life Cycle Assessment with Different Waste Scenarios and a Market Analysis

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Maja Hägesten Nilsson; Albin Kylbrink; [2022]
    Keywords : ;

    Abstract : Hydraulic oils are today most often based on mineral oil and thus eventuate in environmental and climate impacts during all its life cycle phases, but there are bio-based alternatives. Hy- draulic oils are widely used in forklifts, and the use of forklifts is increasing due to logistics within e-commerce. READ MORE

  4. 3. Comparing radar satellites. Use of Sentinel-1 leads to an increase in oil spill alerts in Norwegian waters

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ove Njøten; [2021]
    Keywords : Geography; GIS; Satellite; Radar; Oil spill; Earth and Environmental Sciences;

    Abstract : Radar’s ability to detect oil spills through clouds, fog, and darkness is a significant advantage. Oil spill alert services using radar satellites have been in use in Norway for more than 25 years. After introducing two radar satellites Sentinel-1A and 1B in 2015-2016, the number of oil spill alerts has increased by 250% in Norwegian waters. READ MORE

  5. 4. Comparative life cycle assessment of lubricating greases for nut-runners used in industrial assembly lines

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Pranav Mithra; [2020]
    Keywords : Systems thinking; petroleum; manufacturing; environmental impacts; molybdenum; base oils; additives; thickeners;

    Abstract : Greases are used extensively in almost all areas of life. Considering the fact that they are used in sparing quantities in most applications, the environmental impacts associated with these greases can range from different magnitudes based on the constituents of the grease.

  6. 5. Measurements of resistivity in transformer insulation liquids

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Jonathan Hägerbrand; [2020]
    Keywords : transformer oil; resistivity; ions; ion drift model; HVDC; contact resistance;

    Abstract : This thesis focuses on measuring techniques and results of resistivity in four commercially available insulating transformer oils: mineral oil, ester oil and two isoparaffin oils. Two measuring techniques, the industrially used diagnostic system for electrical insulation IDA and the Labview implemented Triangular Method, are used for resistivity measurements and the techniques are compared, a correction algorithm to the triangular method is suggested.
