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 ... -
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 (Peer reviewed; Journal article, 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 ... -
Performance of MAPA promoted tertiary amine systems for CO2 absorption: Influence of alkyl chain length and hydroxyl groups
Bernhardsen, Ida Mortensen; Krokvik, Iris Renate Tøkje; Jens, Klaus-Joachim; Knuutila, Hanna K (Journal article; Peer reviewed, 2017)Absorption and desorption of CO2 into five aqueous tertiary amine solvents and their blends with MAPA were studied using a screening apparatus. Results showed that MAPA significantly enhanced both CO2 absorption rate and ...
