PVA/nanocellulose nanocomposite membranes for CO2 separation from flue gas
(Peer reviewed; Journal article, 2019)In this paper, we explore the use of nanocelluloses as an additive to poly (vinyl alcohol) (PVA) nanocomposite membranes for CO2/N2 mixed-gas separation. Our findings are that several types of nanocellulose can be used to ... -
PVA/PVP blend polymer matrix for hosting carriers in facilitated transport membranes: Synergistic enhancement of CO2 separation performance
(Journal article; Peer reviewed, 2019)CO2 separation performance in facilitated transport membranes has been reported depended not only on the CO2 carrier properties but also to a great extent on the polymeric matrix regarding the capacity of retaining water ... -
Quantitative Characterization of Absorbents for CO2 Capture
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:221, Doctoral thesis, 2013)Global warming has become one of the world’s most important challenges over the last decades and carbon dioxide (CO2) emissions are determined to be a major contributor. Various carbon dioxide capture and storage (CCS) ... -
Quantitative determination of amines used in post-combustion CO2 capture process by ion chromatography
(Journal article; Peer reviewed, 2015)In post-combustion CO2 capture (PCCC) with amine-based solvents, determining the amount of amine components present in the liquid phase is essential. The quantification of the solvent should be fast, accurate and simple. ... -
Quantitative methods for controlled variables selection
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:168, Doctoral thesis, 2012)Optimal operation is important to improve productivity to be more competitive, and therefore, increase profitability. Optimal operation can be viewed to constitute the control layer (supervisory layer plus regulatory layer) ... -
