Membrane contactor for subsea natural gas dehydration: Model development and sensitivity study
Dalane, Kristin; Svendsen, Hallvard Fjøsne; Hillestad, Magne; Deng, Liyuan (Journal article; Peer reviewed, 2018)A mathematical model of a membrane contactor using triethylene glycol (TEG) for dehydration of natural gas at subsea operation conditions has been developed. The goal for the membrane contactor is to dehydrate the natural ... -
Once-Through Gas-to-Liquid Process Concept for Offshore Applications
Dalane, Kristin (Master thesis, 2015)The worlds energy demand is increasing, and at the same time the amount of easily accessible oil is reduced. Associated gas for most off-shore applications are flared or injected in the reservoir due to transportation ... -
Subsea Natural Gas Dehydration with Membrane Processes
Dalane, Kristin (Doctoral theses at NTNU;2018:326, Doctoral thesis, 2018)Natural gas in the reservoir is saturated with water, which may condense during transportation causing flow assurance problems such as hydrate formation and corrosion. Dehydration of the natural gas is one of the main ... -
Subsea natural gas dehydration with membrane processes: Simulation and process optimization
Dalane, Kristin; Hillestad, Magne; Deng, Liyuan (Peer reviewed; Journal article, 2019)Subsea processing enables broader exploration of oil and gas reservoir, giving an increased focus on developing alternative processes for subsea oil and gas treatment. This work provides a first evaluation of a new proposed ... -
Subsea regeneration of triethylene glycol (TEG) for natural gas dehydration.
Josefsen, Natalie Therese (Master thesis, 2017)The scope of this thesis was to examine the use of pervaporation technology with membranes for the regeneration of triethylene glycol (TEG) in natural gas dehydration. To reduce the need for offshore installations, subsea ... -
Thermopervaporation for regeneration of triethylene glycol (TEG):Experimental and model development
Dalane, Kristin; Josefsen, Natalie Therese; Ansaloni, Luca; Hillestad, Magne; Deng, Liyuan (Journal article; Peer reviewed, 2019)Subsea processing is getting increased interest in the oil and gas sector as it can provide broader exploration of the oil and gas with a lower environmental footprint. Dehydration of natural gas with the use of triethylene ...
