Fabrication and Characterization of Polymeric Membranes for Dehydration of Triethylene Glycol Used for Subsea Application
Lønning, Askild Johannes Balchen (Master thesis, 2019)Hensikten med dette prosjektet er undersøke om en polybenzimidazole (PBI) membran kan brukes til å dehydrere trietylen glykol (TEG) i en pervaporasjons prosess som en del av en membran prosess for dehydrering av naturgass. ... -
Performance of mixed matrix membranes containing porous two-dimensional (2D) and three-dimensional (3D) fillers for CO2 separation: A review
Ahmadi, Mahdi; Janakiram, Saravanan; Dai, Zhongde; Ansaloni, Luca; Deng, Liyuan (Journal article; Peer reviewed, 2018)Application of conventional polymeric membranes in CO2 separation processes are limited by the existing trade-off between permeability and selectivity represented by the renowned upper bound. Addition of porous nanofillers ... -
Performance of Nanocomposite Membranes Containing 0D to 2D Nanofillers for CO2 Separation: A Review
Janakiram, Saravanan; Ahmadi, Mahdi; Dai, Zhongde; Ansaloni, Luca; Deng, Liyuan (Journal article; Peer reviewed, 2018)Membrane technology has the potential to be an eco-friendly and energy-saving solution for the separation of CO2 from different gaseous streams due to the lower cost and the superior manufacturing features. However, the ... -
Solvent Regeneration by Thermopervaporation in Subsea Natural Gas Dehydration: An Experimental and Simulation Study
Ahmadi, Mahdi; Ansaloni, Luca; Hillestad, Magne; Deng, Liyuan (Peer reviewed; Journal article, 2021)An in-house designed membrane process suitable for subsea natural gas dehydration was studied. The use of a membrane absorber together with a thermopervaporation (TPV) unit for solvent regeneration in a closed loop enables ... -
Subsea Natural Gas Treatment Using Membranes: Experimental and Modeling Study
Ahmadi, Mahdi (Doctoral theses at NTNU;2020:367, Doctoral thesis, 2020)Subsea natural gas reservoirs are usually saturated with water vapor and impurities such as CO2 and H2S, which are the main contributors to the pipeline blockage, hydrate formation, and corrosion. Dehydration is usually ...
