Chemical Stability and Characterization of Degradation Products of Blends of 1-(2-Hydroxyethyl)pyrrolidine and 3-Amino-1-propanol
Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Francois, Maxime; Knuutila, Hanna K; Haugen, Geir; Wiig, Merete; Vernstad, Kai (Peer reviewed; Journal article, 2022)Aqueous amine solvents are used to capture CO2 from various flue gas sources. In this work, the chemical stability of a blend of 3-amino-1-propanol (3A1P) and 1-(2-hydroxyethyl)pyrrolidine [1-(2HE)PRLD] was studied. The ... -
Evaluation of Results from SDR Campaigns and Pilot Data
Vevelstad, Solrun Johanne; Grimstvedt, Andreas; Haugen, Geir; Wiig, Merete; Vernstad, Kai (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)For ethanolamine (MEA) many degradation products have been identified and quantified, and the formation of these compounds at different process conditions should be verified. This short paper shows that lab scale experiments, ... -
Multi-component analysis of monethanolamine solvent samples by FTIR
Grimstvedt, Andreas Magnar; Wiig, Merete; Einbu, Aslak; Vevelstad, Solrun Johanne (Journal article; Peer reviewed, 2019)Partial least square regression (PLS-R) methodology have been applied on dataset containing FTIR spectra and densities for a large set of MEA solvent samples. The prediction capabilities for the major compounds were tested ...
