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), ... -
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 ... -
Low-Viscosity Nonaqueous Sulfolane-Amine-Methanol Solvent Blend for Reversible CO2 Capture: Part II. Blend Optimization, Water Effect, and Speciation
Wagaarachchige, Jayangi Dinesha; Idris, Zulkifli; Arstad, Bjørnar; Halstensen, Maths; Jens, Klaus-Joachim (Peer reviewed; Journal article, 2024)This work is part II of the investigation of a low viscosity, low regeneration energy nonaqueous CO2 capture solvent blend consisting of readily available chemicals diisopropylamine (DPA)–methanol–sulfolane and featuring ... -
Pushing Technology Boundaries: Monitoring and Optimization of Carbon Capture Solvents
Wagaarachchige, Jayangi Dinesha (Doctoral dissertations at the University of South-Eastern Norway;196, Doctoral thesis, 2024-05-29)The central idea of the dissertation is to provide insight into options to reducing the cost of amine-based PCC technology. Solvent management and high energy demand are two of the challenges that have increased the ...
