CO2 Absorption Efficiency and Heat Consumption Measured at High Gas to Liquid Ratios in Laboratory Rig
Øi, Lars Erik; Hansen, Per Morten; Henriksen, Mathias (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 ... -
Evaporation characteristics during decompression of liquified CO2 from a conical-shaped vessel
Ibrahim, Osama Kabbashi M.; Hansen, Per Morten; Bjerketvedt, Dag; Vågsæther, Knut (Peer reviewed; Journal article, 2021)Safe transport of pressurized CO2 requires a profound knowledge of the processes' effect during the phase transition on catastrophic failure of a tanker filled with liquid CO2. This study presents experimental results and ... -
Experimental and theoretical studies of rapid phase transitions in CO2
Hansen, Per Morten (Doctoral dissertations at the University of South-Eastern Norway;13, Doctoral thesis, 2018-10-19)Rapid depressurization and evaporation of a pressurized liquefied gas are phenomena of relevance to hazard identification and risk analysis in the process industry. Tank explosions and pipeline ruptures are accident scenarios ... -
Modeling of evaporation of hydrogen during accidental releases
Afzali, Mojtaba (Master thesis, 2021)Hopefully, in the near future, liquid hydrogen will be commonly utilized as energy. The cleanest fuel that the primary limit of producing and using it, is safety issues. High possibility safety issues are generated by large ... -
Modelling of fast fueling of pressurized hydrogen tanks for maritime applications
Kesana, Netaji Ravikiran; Welahettige, Prasanna; Hansen, Per Morten; Ulleberg, Øystein; Vågsæther, Knut (Journal article; Peer reviewed, 2023)This paper studies fast fueling of gaseous hydrogen into large hydrogen (H2) tanks suitable for maritime applications. Three modeling methods have been developed and evaluated: (1) Two-dimensional computational fluid dynamic ... -
Release of liquid CO2 from the bottom of a duct
Mohammed Ibrahim, Osama Kabbashi; Gaathaug, Andre Vagner; Hansen, Per Morten; Bjerketvedt, Dag; Vågsæther, Knut (Peer reviewed; Journal article, 2023)This paper presents experimental results of the rapid phase transition of liquid CO2 released from the bottom of a small rectangular duct (BR). The aim is to consider the factors influencing the phase transitions and the ...
