Absorption and Desorption Study of Alkylamine Promoted DEEA Solvents for CO2 Capture
Bernhardsen, Ida Mortensen; Perinu, Cristina; Jens, Klaus-Joachim; Pinto, Diego Di Domenico; Knuutila, Hanna K (Journal article; Peer reviewed, 2018)Three primary and two secondary mono-alkylamines, and a di-alkylamine (3 (Methylamino)propylamine, MAPA) were investigated in blend with a tertiary amine (2-(Diethylamino)ethanol, DEEA). The aim of the study was to ... -
Aqueous Mapa, DEEA, and Their Blend as CO2 Absorbents: Interrelationship between NMR Speciation, pH, and Heat of Absorption Data
Perinu, Cristina; Bernhardsen, Ida; Pinto, Diego Di Domenico; Knuutila, Hanna K; Jens, Klaus-Joachim (Journal article; Peer reviewed, 2019)On the basis of speciation by nuclear magnetic resonance (NMR) spectroscopy, heat of absorption, and pH data, the reactions occurring in aqueous MAPA (3-(methylamino)propylamine), DEEA (2-(diethylamino)ethanol), and their ... -
Carbon dioxide solubility in mixtures of methyldiethanolamine with monoethylene glycol, monoethylene glycol–water, water and triethylene glycol
Skylogianni, Eirini; Perinu, Cristina; Cervantes Gameros, Blanca Y.; Knuutila, Hanna K (Peer reviewed; Journal article, 2020)Carbon dioxide solubility in non-aqueous and aqueous mixtures of methyldiethanolamine (MDEA) with monoethylene glycol (MEG) was studied due to the relevance of these solvents for the combined acid gas removal and hydrate ... -
CO2 Capture by Aqueous 3-(Methylamino)propylamine in Blend with Tertiary Amines: An NMR Analysis
Perinu, Cristina; Bernhardsen, Ida Mortensen; Svendsen, Hallvard Fjøsne; Jens, Klaus-Joachim (Journal article; Peer reviewed, 2017)Aqueous 3-(Methylamino)propylamine (MAPA) in blend with 2-(Diethylamino)ethanol (DEEA) and other tertiary amines, which mainly differ from DEEA in the number of hydroxyl functions (-OH) and/or in the length and structure ... -
Influence of pKa on solvent performance of MAPA promoted tertiary amines
Bernhardsen, Ida Mortensen; Krokvik, Iris Renate Tøkje; Perinu, Cristina; Pinto, Diego Di Domenico; Jens, Klaus-Joachim; Knuutila, Hanna K (Journal article; Peer reviewed, 2018)In the present work, absorption and desorption performance of ten single tertiary amines and their blends with MAPA was studied using a screening apparatus. Absorption experiments were conducted at 40 °C and up to 9.5 kPa ... -
NMR Speciation of Aqueous MAPA, Tertiary Amines, and Their Blends in the Presence of CO2: Influence of pKa and Reaction Mechanisms
Perinu, Cristina; Bernhardsen, Ida Mortensen; Pinto, Diego Di Domenico; Knuutila, Hanna K; Jens, Klaus-Joachim (Journal article; Peer reviewed, 2018)The diamine 3-(methylamino)propylamine (MAPA) and eight tertiary amines were studied as single and blended aqueous CO2 absorbents at different concentrations and ratios to investigate their reaction mechanisms. After ... -
