Addition of potassium iodide reduces oxidative degradation of monoethanolamine (MEA)
Buvik, Vanja; Ramos Wanderley, Ricardo; Knuutila, Hanna K (Peer reviewed; Journal article, 2021)We introduce the addition of stable salts to aqueous MEA as a way of inhibiting oxidative degradation reactions. We performed oxidative degradation studies in aqueous MEA containing sodium chloride (NaCl) and potassium ... -
Analysis and selection of optimal solvent-based technologies for biogas upgrading
Carranza Abaid, Andres; Ramos Wanderley, Ricardo; Knuutila, Hanna K; Jakobsen, Jana Poplsteinova (Journal article; Peer reviewed, 2021)Biogas upgrading is an important industrial process for producing biomethane, a sustainable energy source with low carbon footprint. There are three main solvent-based alternatives for biogas upgrading: water scrubbing, ... -
Evaluating the possibility of high-pressure desorption of CO2 via volatile co-solvent injection
Ramos Wanderley, Ricardo; Knuutila, Hanna K (Peer reviewed; Journal article, 2021)This work evaluates the possibility of employing a volatile co-solvent injection for recovering CO2 from loaded monoethanolamine at 120 °C under pressures above those achievable through regular desorption processes. This ... -
Introduction of Potassium Iodide as an Inhibitor for Oxidative Degradation of Amines
Buvik, Vanja; Thorstad, Silje; Ramos Wanderley, Ricardo; Knuutila, Hanna K (Chapter, 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 ... -
Signs of alkylcarbonate formation in water-lean solvents: VLE-based understanding of pKa and pKs effects
Ramos Wanderley, Ricardo; Høisæter, Karen Karolina; Knuutila, Hanna K (Peer reviewed; Journal article, 2021)Water-lean solvents are solvents for CO2 capture which contain at least one amine and one organic diluent. Carbamate-forming amines in nonaqueous water-lean solvents typically absorb CO2 through the formation of carbamate ...
