Interfacial mass transfer and bubble hydrodynamics in bubble columns
(Doctoral theses at NTNU;2023:420, Doctoral thesis, 2023)The interaction between gas–liquid or gas–liquid–solid phases exhibit complexity which for years have led researchers to study the intrinsic mechanisms involved. One important branch within multi-phase flow is the interfacial ... -
Interfacial mass transfer limitations in the Fischer-Tropsch synthesis operated in a slurry bubble column at industrial conditions
(Journal article; Peer reviewed, 2018)At high catalyst volume fractions the Fischer-Tropsch synthesis (FTS) operated in a slurry bubble column (SBC) is driven into the mass transfer limited regime. This study utilized literature models for the gas-liquid mass ... -

Interfacial properties of dissolved crude oil components in produced water
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:, Doctoral thesis, 2013)Produced water is a mixture of water trapped in underground formations and injection water that is brought to the surface along with oil or gas. In general, produced water is a mixture of dispersed oil in water (o/w), ... -
Interfacial properties pertinent to W/O and O/W emulsion systems prepared using polyaromatic compounds
(Journal article; Peer reviewed, 2019)Establishing interfacial science to understand molecular mechanisms of stabilizing water in heavy crude oil (W/O) emulsions is challenging due to non-transparent nature of crude oil even in diluted systems, as most of the ... -
Intermediate pressure reboiling in geothermal flash plant for increased power production and more effective non-condensable gas abatement
(Peer reviewed; Journal article, 2019)Non-condensable gases (NCG) in condensing geothermal flash plants have negative effects as they reduce heat transfer and thus deteriorate vacuum in condenser. Therefore, it is necessary to evacuate the condenser by vacuum ... -
Interventions to reduce cadmium exposure in low- and middle-income countries during pregnancy and childhood: A systematic review
(Journal article; Peer reviewed, 2022)Background: Exposure to the toxic metal cadmium is widespread globally and especially prevalent in low- and middle-income countries (LMICs). Early life (from pregnancy through childhood) is a vulnerable window for exposure. ... -
Intracellular pHluorin as Sensor for Easy Assessment of Bacteriocin-Induced Membrane-Damage in Listeria monocytogenes
(Journal article; Peer reviewed, 2018)Bacteriocins are antimicrobial peptides naturally produced by many bacteria and were shown to be effective against various pathogens including Listeria monocytogenes. L. monocytogenes is a food-borne pathogen that frequently ... -
Introducing Video-Recorded Lab Experiments into Assignments for Surface and Colloid Chemistry Students
(Peer reviewed; Journal article, 2022)This communication describes our initial experience modifying traditional (written and calculation-based) assignments in the surface and colloid chemistry course given as a part of the chemical engineering program. The new ... -
Introduction of Potassium Iodide as an Inhibitor for Oxidative Degradation of Amines
(Chapter, 2021)Oxidative degradation of amines for CO2 capture is a challenge that has yet to be overcome. This work presents the potential of using potassium iodide as a stable inhibitor, potentially without the need for replenishment ... -
Invariants for Optimal Operation of Process Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:180, Doctoral thesis, 2011)State of the art strategies to achieve optimal process operation typically employ a hierarchicalcontrol structure, where different tasks are designated to different control layers.In the simplest case there is an optimization ... -
Investigating opportunities for water-lean solvents in CO2 capture: VLE and heat of absorption in water-lean solvents containing MEA
(Journal article; Peer reviewed, 2020)A thorough investigation on a set of organic diluents for water-lean solvent formulation has been carried in this work. The performance of aqueous monoethanolamine (MEA) 30 %w/w has been compared to that of mixtures between ... -
Investigating Protein Adsorption on Hydrophobic and Hydrophilic Polymers for Antifouling Coatings
(Master thesis, 2023)Når overflater befinner seg i sjøvann vil ulike organismer fra sjøen adsorberes på overflaten. Dette fenomenet kalles marin begroing, og har vært et problem i årtusener. Første trinn i prosessen er typisk adsorpsjon av ... -
