Calibration of Pipeline Steel Model for Computational Running Ductile Fracture Assessment
(ISOPE - International Offshore and Polar Engineering Conference. Proceedings;29, Chapter; Peer reviewed, 2019)A novel fracture calibration method is presented for material models applied in finite element analysis of pipeline steels exposed to running ductile fracture. The calibration is based on the drop-weight tear test which ... -
Calorimetric Studies of Precipitating Solvent System
(Peer reviewed; Journal article, 2017)Calorimetric study of a precipitating solvent system of Potassium-Taurate (KTAU) was performed in the CPA202 calorimeter. Two different experiments were conducted, i.e. heat of absorption of CO2 in KTAU solvent at different ... -
Can Heating Induce Borehole Closure?
(Peer reviewed; Journal article, 2020)The current study shows that heating a cased borehole in low-permeability shale rock can induce plastic deformation, leading to the closure of the casing annulus and decreasing annulus connectivity. The thermally induced ... -
Capillary forces as a limiting factor for sawing of ultrathin silicon wafers by diamond multi-wire saw
(Peer reviewed; Journal article, 2020)Succeeding with ultrathin silicon wafer sawing by diamond multi-wire saw, is not only a matter of optimization; the challenges of thin wafer production and the capability limit have not yet been fully understood. In this ... -
Capital cost estimation of CO2 capture plant using Enhanced Detailed Factor (EDF) method: Installation factors and plant construction characteristic factors
(Peer reviewed; Journal article, 2021)Capital cost is frequently estimated for new and retrofit carbon capture plants as new concepts for cost reduction emerge. Capital cost during initial cost estimation of chemical plants strongly depends on the installation ... -
Carbon Capture Utilization and Storage in Methanol Production Using a Dry Reforming-Based Chemical Looping Technology
(Peer reviewed; Journal article, 2022)This further investigates the concept of gas switching dry reforming (GSDR) that efficiently converts the two major greenhouse gases (CO2 and CH4) into a valuable product (syngas) for gas-to-liquid (GTL) syntheses. The ... -
Carbon cathode wear in aluminium electrolysis cells
(Journal article; Peer reviewed, 2019)Autopsies of six spent potlinings with different carbon cathode block grades, amperage regimes and cell technologies were conducted at three separate smelters to reveal possible mechanisms causing cathode wear. Microstructure ... -
Carbon Cathode Wear in Aluminium Electrolysis Cells
(Peer reviewed; Journal article, 2019)Autopsies of six spent potlinings with different carbon cathode block grades, amperage regimes and cell designs were conducted at three separate smelters to reveal possible mechanisms causing cathode wear. The microstructure ... -
Carbon nanofibers have IgE adjuvant capacity but are less potent than nanotubes in promoting allergic airway responses
(Journal article; Peer reviewed, 2013)There is a growing concern for the possible health impact of nanoparticles. The main objective of this study was to investigate the allergy-promoting capacity of four different carbon nanofiber (CNF) samples in an injection ... -
Carbon-negative hydrogen from biomass using gas switching integrated gasification: Techno-economic assessment
(Peer reviewed; Journal article, 2022)Ambitious decarbonization pathways to limit the global temperature rise to well below 2 °C will require large-scale CO2 removal from the atmosphere. One promising avenue for achieving this goal is hydrogen production from ... -
Carbon-negative hydrogen: Exploring the techno-economic potential of biomass co-gasification with CO2 capture
(Peer reviewed; Journal article, 2021)The hydrogen economy is receiving increasing attention as a complement to electrification in the global energy transition. Clean hydrogen production is often viewed as a competition between natural gas reforming with CO2 ... -

A cartesian cut-cell method, based on formal volume averaging of mass, momentum equations
(SINTEF proceedings;2387-4295, Chapter; Peer reviewed, 2017)Simulation of multiphase flows are generally treated by various classes of Eulerian methods, Lagrangian methods and various combinations of these. In the SIMCOFLOW initiative we have set out to develop a framework for ... -
Catalyst Deactivation During One-Step Dimethyl Ether Synthesis from Synthesis Gas
(Peer reviewed; Journal article, 2017)Catalysts for direct synthesis of dimethyl ether (DME) from synthesis gas should essentially contain two functions, i.e., methanol synthesis and methanol dehydration. In the present work, the deactivation of both functions ... -
Catalytic oxidation of NO to NO2 for nitric acid production over a Pt/Al2O3 catalyst
(Peer reviewed; Journal article, 2018)The oxidation of nitric oxide (NO) to nitrogen dioxide (NO2) is a key step both in NOx abatement technologies as well as in the Ostwald process for nitric acid production. A 1 wt.% Pt/Al2O3 catalyst was used to study ... -
Cathode Wear in Electrowinning of Aluminum Investigated by a Laboratory Test Cell
(The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2016)The lifetime of an aluminum electrolysis cell is mainly determined by the cathode wear, especially for high amperage cells utilizing graphitized carbon cathodes. The cathode wear mechanisms are, however, complex and still ... -
