Chemical Stability and Characterization of Degradation Products of Blends of 1-(2-Hydroxyethyl)pyrrolidine and 3-Amino-1-propanol
(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 ... -
Demonstration of a novel instrument for online monitoring of absorber emissions to air
(Peer reviewed; Journal article, 2021)A novel concept for online monitoring of nitrosamines, solvent amines and their degradation products in amine absorber emissions to air was demonstrated at the Tiller CO2-lab pilot facility. The monitoring concept is based ... -
Free Energies of Activation for Viscous Flow of Different Amine Mixtures in Post Combustion CO2 Capture
(SINTEF Proceedings;4, Chapter; Conference object; Peer reviewed, 2019)The viscosity of ternary mixtures of N-methyldiethanol amine (MDEA) + monoethanol amine (MEA) + H2O, Nmethyldiethanol amine (MDEA) + diethanol amine (DEA) + H2O and 2-amino-2-methyl-1-propanol (AMP) + diethanol amine (DEA) ... -
Impact of Solvent on the Thermal Stability of Amines
(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
(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 ... -
Molecular to Process Scale: A Review of Holistic Direct Air Capture Contactor Design
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Air-sorbent contactors are an essential part of direct air capture processes. Their design can have a great influence on the process energy demand and efficiency. Three aspects of this design have been identified and ... -
Stability of Structurally Varied Aqueous Amines for CO2 Capture
(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 ... -
Vapor–liquid equilibria data for 2-piperidineethanol and 1-(2-hydroxyethyl)pyrrolidine in aqueous solutions and a UNIQUAC model representation
(Peer reviewed; Journal article, 2022)This work reports equilibrium data for two amines, 2-piperidineethanol (2-PPE) and 1-(2-hydroxyethyl)pyrrolidine (1-(2HE)PRLD), and their aqueous solutions. The pressure, temperature, and composition data are used to ...
