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 ...
