Prediction of coalescence and rebound of fluid particles in non-Newtonian media through film drainage modeling
(Master thesis, 2023)The drainage of a non-Newtonian film entrapped between two fluid particles that are moving toward one another with time-dependent velocities, causing either coalescence and rebound, is examined in this thesis. Attention ... -

(Doktoravhandlinger ved NTNU, 1503-8181; 2008:123, Doctoral thesis, 2008) -
Preparation and Characterization of Nanosized Structures with Applications in Bioscience and Materials
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:82, Doctoral thesis, 2004)The so-called bottom-up approach to the fabrication of nanostructures from stable building blocks has become a popular theme in current science and engineering. This construction principle mimics e.g. biological systems ... -
Preparation and characterization of pelletized Mn-based sulfur sorbents
(Master thesis, 2021)The global energy situation is changing slowly into new sustainable patterns of production and consumption. However, fossil fuels still lead the world energy outlook, covering more than 80% of the energy mix. Between other ... -
Preparation and Optimization of a Membrane for 3rd Generation Solvent Membrane Contactor
(Master thesis, 2016)Third generation solvent is a new class of CO2 absorbents with a great potential in terms of reduction of the regeneration energy requirement for post combustion carbon capture, but their use at the industrial scale is ... -
Preparation of Carbon Molecular Sieve Membranes with Remarkable CO2/CH4 Selectivity for High-pressure Natural Gas Sweetening
(Peer reviewed; Journal article, 2020)Carbon hollow fiber membranes (CHFMs) were fabricated based on cellulose hollow fiber precursors spun from a cellulose/ionic liquid system. By a thermal treatment on the precursors using a preheating process before ... -
Preparation of cellulose nanofibrils for imaging purposes: comparison of liquid cryogens for rapid vitrification
(Journal article; Peer reviewed, 2018)Artifact-free imaging of cellulose nanofibrils (CNFs) from aqueous nanocellulose suspensions is nontrivial due to frequent irreversible agglomeration and structure damage during the course of sample preparation, especially ... -
Preparation of PVAm/PSf composite hollow fibers for flue gas applications
(Master thesis, 2012)Polysulfone (PSf) hollow fibres as support for Fixed-Site-Carrier (FSC) polyvinylamine (PVAm)/PSf composite membranes used for CO2 capture were attempted optimized by increasing the air gap and take-up speed during spinning. ... -
Preparing a thermodynamic framework for CO2 capture process
(Doctoral theses at NTNU;2016:283, Doctoral thesis, 2016)Summary of thesis: Climate change, with more than 95% certainty, see IPCC 2014, is happening because of anthropogenic CO2 emissions. The easiest and fastest way to cut emissions is CO2 capture and storage. Post combustion ... -
Preperation and characterization of Cu- and Pt-based water-gas shift cataysts
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:123, Doctoral thesis, 2008) -
Pressure Retarded Osmosis and Forward Osmosis Membranes: Materials and Methods
(Journal article; Peer reviewed, 2013)In the past four decades, membrane development has occurred based on the demand in pressure driven processes. However, in the last decade, the interest in osmotically driven processes, such as forward osmosis (FO) and ... -
Pressurized Reduction of Cu-ZnO Water-Gas Shift Catalysts in Presence of Water
(Master thesis, 2015)CuO/ZnO/Al2O3 is a commonly used catalyst for the commercialized water gas shift reaction. Prior to industrial use, CuO has to be reduced to the active metallic copper phase. Yara has experienced major issues as a consequence ... -
Process Concepts for Dehydration of Captured CO2
(Master thesis, 2023)I karbonfangst vil det veldig sjelden fanges helt ren CO2, og det vil typisk være noen urenheter i gasstrømmen, deriblant vann. Dette kan skape problemer for prosessutstyr og transport, og det er derfor ønskelig å senke ... -
Process Integration Applied to the Design and Operation of Distillation Columns
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:24, Doctoral thesis, 2004)Process integration of distillation columns with focus on multi-effect distillation is studied in this thesis. Columns are integrated by using different pressures, so that the condensing duty of one column can be used to ... -
Process Integration of Green Hydrogen: Decarbonization of Chemical Industries
