Experimental Assessment of the Environmental Impact of Ethanolamine
Buvik, Vanja; Strimbeck, Richard; Knuutila, Hanna K. (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)The environmental impact of ethanolamine, a common amine for carbon dioxide capture, was experimentally investigated in laboratory scale microcosms. By exposing the plant-soil systems to varying amounts of ethanolamine, ... -
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 ... -
Introduction of Potassium Iodide as an Inhibitor for Oxidative Degradation of Amines
Buvik, Vanja; Thorstad, Silje; Wanderley, Ricardo R.; Knuutila, Hanna K. (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Oxidative degradation of amines for CO2 capture is a challenge that has yet to be overcome. This work presents the potential of using potassium iodide as a stable inhibitor, potentially without the need for replenishment ... -
A review of degradation and emissions in post-combustion CO2 capture pilot plants
Buvik, Vanja; Høisæter, Karen Karolina; Vevelstad, Solrun Johanne; Knuutila, Hanna K (Peer reviewed; Journal article, 2021)Pilot plant testing of amine solvents for post-combustion CO2 capture is an essential tool for fully understanding degradation behaviour and emission profiles under realistic process conditions. This review aims to summarise ... -
Stability of Structurally Varied Aqueous Amines for CO2 Capture
Buvik, Vanja; Vevelstad, Solrun Johanne; Brakstad, Odd Gunnar; Knuutila, Hanna K (Peer reviewed; Journal article, 2021)Eighteen structurally varied amines were subjected to harsh oxidative conditions, and their stability was assessed and seen in the context of biological and thermal stability. Steric effects play a large role in the ...
