Corrosion and degradation in MEA based post-combustion CO2 capture
(Journal article; Peer reviewed, 2016)Two of the main challenges in post-combustion CO2 capture with ethanolamine are solvent degradation and material corrosion. It has been shown that there is a correlation between degradation and corrosion. The present paper ... -
Corrosion Evaluation of MEA Solutions by SEM-EDS, ICP-MS and XRD
(Journal article; Peer reviewed, 2016)The target of this work is to evaluate three analytical techniques, ICP-MS, SEM-EDS and XRD, which can be applied in corrosion monitoring of ethanolamine based post-combustion CO2 capture plants. The work is based on ... -
Corrosion of Copper and Oxidation of Dielectric Liquids in High Voltage Transformers
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:196, Doctoral thesis, 2013)Breakdowns in high voltage transformers are of major concern. It is therefore a goal to prevent this from happening. Chemical degradation (e.g. oxidation, hydrolysis and corrosion) of the insulation systems and windings ... -
Cost-efficient core-shell TS-1/silicalite-1 supported Au catalysts: Towards enhanced stability for propene epoxidation with H2 and O2
(Journal article; Peer reviewed, 2018)Designing cost-effective TS-1 with enhanced catalytic stability in direct propene epoxidation with H2 and O2 is attracting tremendous research interests. In this work, a novel hydrophobic TS-1/S-1 lamellar support with ... -
Creating a machine learning based surrogate model for modelling of a carbon capture plant
(Master thesis, 2022)Dagens metoder for å gjøre en parameterstudie av et karbonfangstanlegg er ofte en treg prosess som krever mye innsats og manuell input. For å gjøre denne pros- essen mindre arbeidskrevende ble et neuralt nettverk konstruert ... -
Critical review of catalysis for ethylene oxychlorination
(Peer reviewed; Journal article, 2020)Ethylene oxychlorination is the key technology in vinyl chloride (VCM, the monomer of PVC, polyvinyl chloride) production to close the chlorine loop by consuming the HCl released from the former cracking step. Due to the ... -
Cross-linked PEG Membranes of Interpenetrating Networks with ILs as Additives for Enhanced CO2 Separation
(Journal article; Peer reviewed, 2019)Polyethylene glycol (PEG)-based membranes have recently been reported with excellent CO2 separation performances. However, the commonly exhibited high crystallinity may deteriorate the gas permeation properties in this ... -
Cross-linked PEG/ ionic liquid composite membranes for CO2 separation
(Master thesis, 2018)The increasing CO2 emission has become an urgent issue in the past decades. Comparing with other traditional CO2 separation technologies such as amino absorption, membrane separation has been considered as a potential ... -
Cross-linking oxidized cellulose nanofibrils for the formation of stable hydrogel structures
(Master thesis, 2013)The main goal of this project was to investigate whether the elastic properties of microfibrillated cellulose (MFC) suspensions pre-treated by TEMPO-mediated oxidation could be controlled by inducing cross-links between ... -
Crosslinking and Stabilization of High Free Volume Polymers for Gas Separations
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:189, Doctoral thesis, 2008) -
Crystal Growth and Morphology Development from Aqueous Solutions
(Doctoral theses at NTNU;2022:265, Doctoral thesis, 2022)Crystalline materials are found in a numerous variety of geometrical forms both in nature and when produced synthetically. As a result, pathways of crystal nucleation, growth and assembly into larger structures have evoked ... -
Crystal Growth Kinetics of Calcium Carbonate Particles in Natural Gas Production
(Master thesis, 2012)Precipitation of calcium carbonate particles is an interesting area in natural gas production. The inorganic salt could be formed due to pH stabilization for corrosion control in the pipelines and during the regeneration ... -
