1. 1. Preparation and Experimental Investigation of the Tribological Properties of Conductive Grease Containing Ionic Liquids

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Gabriella Johansson Segervall; [2022]
   Keywords : Ionic liquids; bearing current; tribology; conductive grease;

   Abstract : This thesis project was executed at ABB AB. The purpose of the thesis was to formulate aselection of ionic liquids with different thickeners as greases and experimentally understand thetribological characteristics and electrical properties. READ MORE

3. 2. Algae hydrocarbons designed for bio-based lubricants

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Elin Sjöhag; [2020]
   Keywords : Microalgae; macroalgae; lubricant; alginate; grease; Mikroalger; makroalger; smörjmedel; alginat; förtjockningsmedel;

   Abstract : Smörjmedel är en nödvändighet för maskiner för att minska slitage och energiförbrukning. Dock är över 95% av de använda smörjmedlen i dag fossilbaserade. Smörjmedel baserade på vegetabiliska oljor finns tillgängliga men har ofta en lägre oxidativ stabilitet och sämre lågtemperaturegenskaper än deras fossilbaserade motsvarigheter. READ MORE

4. 3. 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. READ MORE

5. 4. Optimal control of clarifier-thickeners

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Sakari Teerikoski; [2017]
   Keywords : clarifier; thickener; modelling; simulation; control; cascade control; settling;

   Abstract : A computer model for a general clarifier-thickener has been made and used for comparing different strategies for control of such dewatering units through simulations. The model builds on widely acknowledged theory for modelling clarifier-thickeners - discretizing the settling PDE into a set of ODEs so that concentrations of solids at discrete depths inside the unit become the states of the numerical model - and it was written in the Modelica language using the modelling and simulation environment Dymola.
