Demonstration of CO2 Capture Process Monitoring and Solvent Degradation Detection by Chemometrics at the Technology Centre Mongstad CO2 Capture Plant
Wagaarachchige, Jayangi Dinesha; Idris, Zulkifli; Khatibzadeh, Ayandeh; Drageset, Audun; Jens, Klaus-Joachim; Halstensen, Maths (Peer reviewed; Journal article, 2023)Solvent management is one of the important current challenges in post combustion carbon capture (PCC) technology development. Using large-scale 1960 h test campaign data (Technology Centre Mongstad, Norway, 2015 MEA Test), ... -
Equilibrium Measurements of the NH3-CO2-H2O System: Speciation Based on Raman Spectroscopy and Multivariate Modeling
Halstensen, Maths; Jilvero, Henrik; Jinadasa, Wathsala; Jens, Klaus-Joachim (Journal article; Peer reviewed, 2017)Liquid speciation is important for reliable process design and optimization of gas-liquid absorption process. Liquid-phase speciation methods are currently available, although they involve tedious and time-consuming ... -
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 ... -
Raman Spectroscopy as an Online Monitoring Tool for CO2 Capture Process: Demonstration Using a Laboratory Rig
Jinadasa, Wathsala; Jens, Klaus-Joachim; Øi, Lars Erik; Halstensen, Maths (Journal article; Peer reviewed, 2017)A laboratory CO2 capture rig at USN was used as a demonstration plant to show the feasibility of Raman spectroscopy for online monitoring of speciation in CO2 capture process. The spectroscopy was integrated to lean and ... -
Spray drop size characterization in an external-mixing bluff-body atomizer based on acoustics and Multivariate Analysis
Sikka, Raghav; Halstensen, Maths; Lundberg, Joachim (Peer reviewed; Journal article, 2022)Air-assist atomizers have been widely used in various applications such as the aerospace industry, internal combustion engines, molten metal, food processing, etc. The mean drop size for these atomizers was obtained through ...
