Characterization of 2-Piperidineethanol and 1-(2-Hydroxyethyl)piperidine as strong bicarbonate forming solvents for CO2 Capture
Hartono, Ardi; Rennemo, Rune; Awais, Muhammad; Vevelstad, Solrun Johanne; Brakstad, Odd Gunnar; Kim, Inna; Knuutila, Hanna K (Journal article; Peer reviewed, 2017-08)The solubility of CO2 in the aqueous solutions of 50 mass% 2-Piperidineethanol (2-PPE) and 40 mass% 1-(2-Hydroxyethyl)pyrrolidine (1-(2HE)PRLD) was measured at temperatures from 40 to 120 °C at CO2 loading from 0.04 to 0.8 ... -
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 ... -
Comparison of different solvents from the solvent degradation rig With real samples
Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Haugen, Geir; Kupfer, Rene; Brown, Nathan; Einbu, Aslak; Vernstad, Kai; Zahlsen, Kolbjørn (Journal article; Peer reviewed, 2017) -
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, ... -
Exploration of degradation chemistry by Advanced analytical methodology
Grimstvedt, Andreas Magnar; Zahlsen, Kolbjørn; Vevelstad, Solrun Johanne; Vernstad, Kai; Holten, Torunn; Brunsvik, Anders (Journal article; Peer reviewed, 2017) -
Impact of Solvent on the Thermal Stability of Amines
Høisæter, Karen Karolina; Vevelstad, Solrun Johanne; Braakhuis, Lucas; Knuutila, Hanna K (Peer reviewed; Journal article, 2022)Water-lean solvents have been proposed as a possible alternative to aqueous amine systems in postcombustion carbon capture. There is however little data available on how amine degradation is affected by different solvents. ... -
Important Aspects Regarding the Chemical Stability of Aqueous Amine Solvents for CO2 Capture
Vevelstad, Solrun Johanne; Buvik, Vanja; Knuutila, Hanna K; Grimstvedt, Andreas Magnar; Silva, Eirik Falck da (Peer reviewed; Journal article, 2022)The chemical stability of aqueous amines is an essential property to study before new amines are introduced in pilot plants, to reduce risks related to the operation, cost and environment. There are no standard methods for ... -
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 ... -

Use of metal-organics based solvents for CO2 capture
Heyn, Richard H; Aronu, Ugochukwu Edwin; Vevelstad, Solrun Johanne; Hoff, Karl Anders; Didriksen, Terje; Arstad, Bjørnar; Blom, Richard (Journal article; Peer reviewed, 2014)There are a number of metal-organic compounds that can loosely be considered CA mimics and which are known to absorb CO2 directly from the atmosphere. The metal-organic complex, {Zn[N[CH2(2-py)]3](μ-OH)}2(NO3)2 (I), is one ...
