CO2 solubility and mass transfer in water-lean solvents
Wanderley, Ricardo Ramos; Yuan, Ye; Rochelle, Gary T.; Knuutila, Hanna K (Journal article; Peer reviewed, 2019)Shifting from aqueous to water lean solvents has been evaluated as a mean for increasing the mass transfer rates in regular chemical solvents with amines. An array of amines (monoethanolamine, 2-methylpiperazine and N-methyl ... -
Density and Viscosity for the Non-aqueous and Aqueous Mixtures of Methyldiethanolamine and Monoethylene Glycol at Temperatures from 283.15 K to 353.15 K
Skylogianni, Eirini; Wanderley, Ricardo Ramos; Austad, Sigrid Steinsli; Knuutila, Hanna K (Journal article; Peer reviewed, 2020)Nonaqueous and aqueous mixtures of methyldiethanolamine and monoethylene glycol form promising absorbents for the combined hydrogen sulfide removal and hydrate control, necessary in natural gas processing. In this direction, ... -
From hybrid solvents to water-lean solvents – A critical and historical review
Wanderley, Ricardo Ramos; Pinto, Diego Di Domenico; Knuutila, Hanna K (Journal article; Peer reviewed, 2020)Every year, a plethora of studies focused on developing water-lean solvents for CO2 capture is published in the scientific literature. More often than not, these studies lack a satisfactory contextualization with the ... -
Investigating opportunities for water-lean solvents in CO2 capture: VLE and heat of absorption in water-lean solvents containing MEA
Wanderley, Ricardo Ramos; Pinto, Diego Di Domenico; Knuutila, Hanna K (Journal article; Peer reviewed, 2020)A thorough investigation on a set of organic diluents for water-lean solvent formulation has been carried in this work. The performance of aqueous monoethanolamine (MEA) 30 %w/w has been compared to that of mixtures between ... -
Mapping Diluents for Water-Lean Solvents: A Parametric Study
Wanderley, Ricardo Ramos; Knuutila, Hanna K (Peer reviewed; Journal article, 2020)Water-lean solvents are typically defined as mixtures between an organic diluent and an amine. These solvents are thought to deliver potential benefits in CO2 capture systems, such as enhanced mass transfer properties, ... -
Modeling of CO2 Capture using Machine Learning: A data-driven approach for specific reboiler duty prediction of a pilot plant
Li, Jun Xing (Master thesis, 2024)Nasjoner over hele verden streber etter å nå målene for utslippsreduksjon fastsatt i Parisavtalen, og i den anledning spiller karbonfangst og -lagring en avgjørende rolle i å redusere klimagassutslipp. Det fullskala ... -
Solubility and Heat of Absorption of CO2 into Diisopropylamine and N,N-Diethylethanolamine Mixed with Organic Solvents
Wanderley, Ricardo Ramos; José Caballero Ponce, Gonzalo; Knuutila, Hanna K (Journal article; Peer reviewed, 2020)We have evaluated the vapor–liquid equilibrium and heat of absorption of CO2 over water-lean mixtures of the amines diisopropylamine and N,N-diethylethanolamine (DEEA). This extends our previous research on water-lean ... -
Solubility of Carbon Dioxide, Hydrogen Sulfide, Methane, and Nitrogen in Monoethylene Glycol; Experiments and Molecular Simulation
Dawass, Noura; Wanderley, Ricardo Ramos; Ramdin, Mahinder; Moultos, Othonas A.; Knuutila, Hanna K; Vlugt, Thijs J.H. (Peer reviewed; Journal article, 2020)Knowledge on the solubility of gases, especially carbon dioxide (CO2), in monoethylene glycol (MEG) is relevant for a number of industrial applications such as separation processes and gas hydrate prevention. In this study, ... -
The Salting-out Effect in Some Physical Absorbents for CO2 Capture
Wanderley, Ricardo Ramos; Evjen, Sigvart; Pinto, Diego Di Domenico; Knuutila, Hanna K (Journal article; Peer reviewed, 2018)The solubility of CO2 in organic solvents N-methyl-2-pyrrolidone (NMP), methanol and monoethylene glycol (MEG) at 30 °C was measured together with its heat of absorption. The salts lithium nitrate (LiNO3), lithium chloride ... -

The ... -
Water-lean solvents for biogas upgrading
Wanderley, Ricardo Ramos (Doctoral theses at NTNU;2020:298, Doctoral thesis, 2020)Biogas upgrading consists in the removal of CO2 from biogas, a process which produces a highly purified biomethane stream. As such, biogas upgrading has a double positive impact when considering climate change mitigation ...
