Selection and characterization of phase-change solvent for carbon dioxide capture: precipitating system
(Peer reviewed; Journal article, 2013)Characterization of a precipitating solvent for CO2 capture was performed. Aqueous solution of 5m’ potassium salt of sarcosine (KSar) that was precipitated at CO2 loading of 0.52 was selected. The equilibrium solubility ... -
Evaluation of a filtered model for the simulation of large scale bubbling and turbulent fluidized beds
(Peer reviewed; Journal article, 2013)Full 3D flow simulations of lab and industrial scale dense fluidized beds were carried out using a filtered Eulerian-Eulerian approach. Filtered closures for interphase momentum exchange, solids stresses and additional ... -
Experimental Demonstration of a Novel Gas Switching Combustion Reactor for Power Production with Integrated CO2 Capture
(Peer reviewed; Journal article, 2013)This paper experimentally demonstrates the feasibility of a novel gas switching combustion (GSC) reactor as an alternative to the traditional chemical looping combustion (CLC) process for power production with integrated ... -
CO2 pipeline integrity: A coupled fluid-structure model using a reference equation of state for CO2
(Peer reviewed; Journal article, 2013)We present a coupled fluid-structure model to study crack propagation and crack arrest in pipelines. Numerical calculations of crack arrest, crack velocity and pressure profiles have been performed for steel pipes with an ... -
Influence of dispersoids on microstructure evolution and work hardening of aluminium alloys during tension and cold rolling
(Peer reviewed; Journal article, 2013)The influence of dispersoids on work hardening of aluminium during tension and cold rolling has been studied by comparing Al–Mn alloys containing similar amounts of solutes but various dispersoid densities. The microstructure ... -
Muon kinetics in heat treated Al (–Mg)(–Si) alloys
(Peer reviewed; Journal article, 2013)Al–Mg–Si alloys are heat-treatable and rely on precipitation hardening for their mechanical strength. We have employed the technique of muon spin relaxation to further our understanding of the complex precipitation sequence ... -
Recycling of the Rare Earth Oxides from Spent Rechargeable Batteries Using Waste Metallurgical Slags
(Journal article; Peer reviewed, 2013)A high temperature process for recycling spent nickel-metal hydride rechargeable batteries has been recently developed at SINTEF/NTNU. The spent battery modules were first frozen with liquid nitrogen for the de-activation ... -
CCS status – Input to the CSLF Technology Roadmap 2013
(SINTEF Energi. Rapport;, Research report, 2013)The Carbon Sequestration Leadership Forum (CSLF) Technical Group has decided to update its Technology Roadmap from 2011 and to present this new roadmap at the 5th CSLF Ministerial Meeting in Houston, USA in November 2013. ... -
A numerical solution strategy for dynamic simulation of post-combustion CO2 capture
(Peer reviewed; Journal article, 2013)This paper describes in detail the numerical solution of a dynamic process developed for post-combustion absorption based CO2 capture. The method used in this work is sequential modular integration. This means that each ... -
How calcium prevents precipitation hardening in Al–Mg–Si alloys
(Peer reviewed; Journal article, 2013)We have investigated the effect on precipitate microstructure and hardness upon adding small amounts of Ca to a base Al–Mg–Si alloy. The main investigative techniques were transmission and scanning electron microscopy. We ... -
A comparative analysis of the properties of regulated promoter systems commonly used for recombinant gene expression in Escherichia coli
(Journal article; Peer reviewed, 2013)Background Production of recombinant proteins in bacteria for academic and commercial purposes is a well established field; however the outcomes of process developments for specific proteins are still often unpredictable. ... -
A standardized Approach to Multi-criteria Assessment of CCS Chains
(Peer reviewed; Journal article, 2013)For a commercial Carbon Capture and Storage (CCS) chain to be successful, it must satisfy a whole range of requirements: technical, economic, environmental, safety, and societal. A comprehensive, understandable and ... -
