Application of 15N-NMR spectroscopy to analysis of amine based CO2 capture solvents
(Journal article; Peer reviewed, 2014)15N NMR spectroscopy is a useful tool for amine reactivity characterization since it can provide information about the availability of the lone pair of electrons on nitrogen through the measured chemical shift values, which ... -
CO2 Absorption Efficiency and Heat Consumption Measured at High Gas to Liquid Ratios in Laboratory Rig
(Journal article; Peer reviewed, 2017)A laboratory rig for CO2 absorption into amine solvents including desorption has been in operation at University College of Southeast Norway for several years. Measurements of CO2 removal efficiency and heat consumption ... -
CO2 Capture by Aqueous 3-(Methylamino)propylamine in Blend with Tertiary Amines: An NMR Analysis
(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 ... -
CO2stCap - Cutting Cost of CO2 Capture in Process Industry
(Journal article; Peer reviewed, 2017)This paper is a presentation of the CO2stCap project to be undertaken in the four year project period (2015 – 2019). The project focuses on partial CO2 capture in process industry and how this can be applied to reduce cost. ... -
Energy and Economic Analysis of Improved Absorption Configurations for CO2 Capture
(Journal article; Peer reviewed, 2017)The shortcoming of amine-based CO2 absorption technology is the large heat demand for desorption and it requires huge capital investment. Thus, it is expedient to comprehensively and critically analyse alternative process ... -
Investigation into optimal CO2 concentration for CO2 capture from aluminium production
(Journal article; Peer reviewed, 2013-08-05)Capture of CO2 from aluminum production has been simulated using Aspen Plus and Aspen Hysys. The technology used for aluminum production is the Hall-Héroult and the current cell design necessitates that large amounts of ... -
Performance of MAPA promoted tertiary amine systems for CO2 absorption: Influence of alkyl chain length and hydroxyl groups
(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 ... -
Raman Spectroscopy as an Online Monitoring Tool for CO2 Capture Process: Demonstration Using a Laboratory Rig
(Journal article; Peer reviewed, 2017)A laboratory CO2 capture rig at USN was used as a demonstration plant to show the feasibility of Raman spectroscopy for online monitoring of speciation in CO2 capture process. The spectroscopy was integrated to lean and ... -

The Activator Mechanism of Piperazine in Aqueous Methyldiethanolamine Solutions
(Journal article; Peer reviewed, 2017)Piperazine (PZ) is added to aqueous methyldiethanolamine (MDEA) solutions to achieve a greater CO2 absorption in CO2 capture technology. It is referred to as “activated MDEA solutions” in the industry. However, does PZ ...
