A Study of Mass Transfer Kinetics of Carbon Dioxide in (Monoethanolamine + Water) by Stirred Cell
Ying, Jiru; Eimer, Dag-Arne (Journal article; Peer reviewed, 2013-08-05)The gas phase resistance in a stirred cell was investigated to understand and avoid its influence on the measurement of the reaction kinetics. To validate the influence of gas phase resistance and the experimental conditions ... -
Mass Transfer Kinetics of Carbon Dioxide into Concentrated Aqueous Solutions of Monoethanolamine
Ying, Jiru (Doctoral dissertations at TUC;2013:2, Doctoral thesis; Peer reviewed, 2013-02-15)Global warming arguments have gained more and more attention due to the new regulations of carbon dioxide (CO2) emission in the world. Monoethanolamine (MEA) has been employed as an important industrial absorbent for CO2 ... -
The Activator Mechanism of Piperazine in Aqueous Methyldiethanolamine Solutions
Ying, Jiru; Raets, Stef; Eimer, Dag-Arne (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 ... -
Ultrasound intensified CO2 desorption from pressurized loaded monoethanolamine solutions. I. parameters investigation and modelling
Ying, Jiru; Eimer, Dag-Arne; Brakstad, Frode; Haugen, Hans Aksel (Journal article; Peer reviewed, 2018)CO2 stripping from loaded monoethanolamine (MEA) aqueous solutions intensified by means of ultrasound was investigated in a lab-scale kettle reboiler with both gas and liquid continuous operations. The reboiler operating ... -
Ultrasound intensify CO2 desorption from pressurized loaded monoethanolamine solutions. II. Optimization and cost estimation
Ying, Jiru; Eimer, Dag-Arne; Mathisen, Anette; Brakstad, Frode; Haugen, Hans Aksel (Journal article; Peer reviewed, 2019)Optimization and cost estimation were performed for the use of ultrasound for intensifying CO2 reboiler stripping from lean monoethanolamine (MEA) aqueous solutions at 1.0 barg. This work was based on typical industrial ...
