CCS in the Skagerrak/Kattegat area
(Journal article; Peer reviewed, 2011-04-01)This paper presents an ongoing project with the aim to assess a CO2 infrastructure in the Skagerrak/Kattegat region (the sea bordered by north of Denmark, south coast of Norway and the west coast of Sweden). The area ... -
Biological treatment of amine wastes generated in post combustion CO2 capture
(Journal article; Peer reviewed, 2011)The wastes generation by amine degradation is an important issue to be addressed when considering CCS schemes. Biological treatment of amine wastes can be a strategy with reasonable economy and environmental sustainability. ... -
NEQ rate based modeling of an absorption column for post combustion CO2 capturing
(Journal article; Peer reviewed, 2011-04-01)Post combustion CO2 capture via absorption into aqueous alkanolamine systems is considered to be the most mature and potential technique for CO2 removal from the power plants' exhaust gases. Modeling and simulation of such ... -
Development of normal pressure and frictional traction along the walls of a steep conical hopper during filling
(Journal article; Peer reviewed, 2011)A novel progressive filling approach was adopted in a numerical effort to represent the pilling process of particulate solids. It was implemented in a finite element analysis to investigate the development of loads along ... -
Case studies of CO2 capture columns based on fundamental modeling

Experimental investigation of load exerted on a double-cone insert and effect of the insert on pressure along walls of a large-scale axisymmetrical silo
(Journal article; Peer reviewed, 2011-03-03)Applications of flow aid devices (commonly referred as inserts) improve the silo discharging mode. Considerable efforts have been made in finding best configurations between the inserts and silos to achieve the optimal ... -
Men's artistic gymnastics: a new high bar-gymnast model with sensitivity analysis
(Journal article; Peer reviewed, 2011)The purpose of this work1 was to develop a new 2D gymnast - high bar model with horizontal bar endpoint dynamics included. To this end, a three-spring high bar model was extended with a 5 segment gymnast model followed by ... -
Oxygen effects in anaerobic digestion - a review
(Journal article; Peer reviewed, 2011)This article reviews the experimental and theoretical studies conducted on the possible effects of oxygen in biogas generating anaerobic digesters. The interactions of oxygen with various biochemical processes associated ... -
Fra fagbrev til ingeniør - et didaktisk perspektiv
(Journal article; Peer reviewed, 2011)Veien fra fagbrev eller annen yrkesutdanning til høgere utdanning har vært et tema i den norske skoledebatten i mange år, og er igjen blitt aktuell. Land som Finland, Tyskland og Japan har etablerte systemer for høgere ... -
Process parameters affecting the sustainability of fermentative hydrogen production: A short review
(Journal article; Peer reviewed, 2011)Anaerobic fermentation is regarded as the least energy intensive method for H2 production. Extensive literature on experimental attempts to achieve the highest possible theoretical yield (e.g. 4 mol H2/mol glucose) is ... -
Effect of operating conditions and particle properties on performance of vertical air-lift
(Journal article; Peer reviewed, 2011)The effect of the fluidization air flow rate and the transport air velocity on the solids mass flow rate and the pressure drop along the transport pipe was investigated in a vertical air-lift. The use of two different ... -
The Influence of the Physical Characteristics of Particulate Materials on their Conveyability in Pneumatic Transport Systems
(Doctoral thesis; Peer reviewed, 1996-12)The aim of the investigation has been to establish a link between the physical characteristics of particulate materials, measurable on small samples in a laboratory, and the conveyability of these materials in a pneumatic ... -
Simulation of flame acceleration and DDT in H-2-air mixture with a flux limiter centered method
(Journal article; Peer reviewed, 2007)Flame acceleration and deflagration to detonation transition (DDT) is simulated with a numerical code based on a flux limiter centered method for hyperbolic differential equations. The energy source term is calculated by ... -

Oxygen Effects in Anaerobic Digestion II
(Journal article, 2010)Standard models describing bio-gasification using anaerobic digestion do not include necessary processes to describe digester dynamics under the conditions of oxygen presence. Limited oxygenation in anaerobic digestion can ... -
Experiments with flame propagation in a channel with one obstacle and premixed H2-air
(Conference object; Peer reviewed, 2009-07)This abstract presents experimental results of flame propagation in a square channel with a single obstacle. The background for the experimental study was to investigate how a flame propagated when and after the flame ... -
Quantification of biofilm accumulation by an optical approach
(Journal article; Peer reviewed, 2001-02)Methods for non-invasive, in situ, measurements of biofilm optical density and biofilm optical thickness were evaluated based on Pseudomonas aeruginosa experiments. Biofilm optical density, measured as intensity reduction ... -
Effects of initial molecular weight on removal rate of dextran in biofilms
(Journal article; Peer reviewed, 2006-05)Degradation kinetics of different size dextrans in a biofilm reactor were evaluated. Degradation rates of dextran standards, measured as time series of oxygen utilisation rates (OUR), decreased with increasing initial ... -
Velocity and turbulence measurements of oil-water flow in horizontal and slightly inclined pipes using PIV
(Chapter; Peer reviewed, 2009)Oil-water flows in horizontal and slightly inclined pipes are investigated using Particle Image Velocimetry (PIV). PIV offers a powerful non-invasive tool to study such flow fields. The experiments are conducted in a 15 m ...
