Alumina scale composition and growth rate in distribution pipes
Haugland, Ingrid Bokn; Kjos, Ole Sigmund; Røyset, Arne Karstein; Vullum, Per Erik; Aarhaug, Thor Anders; Halstensen, Maths (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2019)Scaling in distribution pipes for secondary alumina is a major issue in aluminium smelters. The scale is formed inside the distribution pipes, and gradually reduces the cross section that is available for alumina transport. ... -
Fast Water-Lean Solvent Screening using FTIR Spectroscopy: In-Situ (In-Line) Monitoring using an ATR Raction Cell Integrated with On-Line Monitoring Attached to a Lquid-Flowcell
Wagaarachchige, Jayangi D.; Idris, Zulkifli; Halstensen, Maths; Jens, Klaus-J. (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)This study presents a fast and precise solvent characterizing method for the screening of novel CO2 capture systems. In this method, time-base Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy ... -
High Concentrated Mea Solvent Systems for CO2 Absorption - An FT-NIR and Raman Spectroscopic Investigation
Jinadasa, M.H. Wathsala N.; Badalge, Jayalanka Liyana; Halstensen, Maths; Eimer, Dag; Jens, Klaus-Joachim (SINTEF Proceedings;4, Chapter; Conference object; Peer reviewed; Chapter, 2019)This study investigates the use of Fourier Transform Near-Infrared (FT-NIR) spectroscopy and Raman spectroscopy to monitor the CO2 absorption process when over 65 wt % concentrated monoethanolamine (MEA) solutions are used. ... -
Low-Viscosity Nonaqueous Sulfolane-Amine-Methanol Solvent Blend for Reversible CO2 Capture
Wagaarachchige, Jayangi Dinesha; Idris, Zulkifli; Arstad, Bjørnar; Kummamuru, Nithin Bharadwaj; Sætre, Kai Arne; Halstensen, Maths; Jens, Klaus-Joachim (Peer reviewed; Journal article, 2022)In this work, the absorption–desorption performance of CO2 in six new solvent blends of amine (diisopropylamine (DPA), 2-amino-2-methyl-1-propanol (AMP), methyldiethanolamine (MDEA), diethanolamine (DEA), diisopropanolamine ... -
Monitoring of Erosion in a Pneumatic Conveying System by Non-intrusive Acoustic Sensors – A Feasibility Study
Haugland, Ingrid Bokn; Chladek, Jana; Halstensen, Maths (Peer reviewed; Journal article, 2019)This paper presents the results of a study where the feasibility of a non-invasive acoustic measurement method was tested for monitoring of erosion in a pneumatic conveying system during the ... -
Monitoring of scale formation in a pneumatic conveying system operating in a metal production plant
Haugland, Ingrid Bokn; Chladek, Jana; Halstensen, Maths (Journal article; Peer reviewed, 2019)Monitoring of scale progression in a pneumatic conveying system operating in a metal production plant was conducted during a five-month long monitoring period. A combination of an acoustic monitoring method and a laser ...
