Effects of salinity on hydrate stability and implications for storage of CO2 in natural gas hydrate reservoirs
Husebø, Jarle; Ersland, Geir; Graue, Arne; Kvamme, Bjørn (Peer reviewed; Journal article, 2009-02)The win-win situation of CO2 storage in natural gas hydrate reservoirs is attractive for several reasons in addition to the associated natural gas production. Since both pure CO2 and pure methane form structure I hydrate ... -
Enthalpies of Hydrate Formation and Dissociation from Residual Thermodynamics
Aromada, Solomon Aforkoghene; Kvamme, Bjørn; Wei, Na; Saeidi, Navid (Journal article; Peer reviewed, 2019-12-11)We have proposed a consistent thermodynamic scheme for evaluation of enthalpy changes of hydrate phase transitions based on residual thermodynamics. This entails obtaining every hydrate property such as gas hydrate ... -
Hydrate Nucleation, Growth, and Induction
Kvamme, Bjørn; Aromada, Solomon Aforkoghene; Saeidi, Navid; Hustache-Marmou, Thomas; Gjerstad, Petter Berge (Journal article; Peer reviewed, 2020)The first stage of any phase transition is a dynamic coupling of transport processes and thermodynamic changes. The free energy change of the phase transition must be negative and large enough to also overcome the penalty ... -
Hydrate Production Philosophy and Thermodynamic Calculations
Kvamme, Bjørn; Zhan, Jinzhou; Wei, Na; Sun, Wantong; Saeidi, Navid; Pei, Jun; Kuznetsova, Tatiana (Journal article; Peer reviewed, 2020)The amount of energy in the form of natural gas hydrates is huge and likely substantially more than twice the amount of worldwide conventional fossil fuel. Various ways to produce these hydrates have been proposed over the ... -
Modeling Heat Transport in Systems of Hydrate-Filled Sediments Using Residual Thermodynamics and Classical Nucleation Theory
Zarifi, Mojdeh; Kvamme, Bjørn; Kuznetsova, Tatiana (Journal article; Peer reviewed, 2021)As in any other phase transition, hydrate phase transition kinetics involves an implicit coupling of phase transition thermodynamic control and the associated dynamics of mass and heat transport. This work provides a brief ... -
Molecular Dynamics Study of Selective Adsorption of PCB on Activated Carbon
Jensen, Bjørnar; Kuznetsova, Tatiana; Kvamme, Bjørn; Oterhals, Åge (Journal article, 2011)The selectivity of PCB adsorption from fish oil onto activated carbon (AC) was investigated by means of molecular dynamics to determine the importance of molecular planarity. PCB congeners 77 and 118 were selected for ... -
Numerical Modeling of Supercritical ‘Out-Salting’ in the “Atlantis II Deep” (Red Sea) Hydrothermal System
Hovland, Martin; Rueslåtten, Håkon; Kuznetsova, Tatiana; Kvamme, Bjørn; Fladmark, Gunnar E.; Johnsen, Hans Konrad (Peer reviewed; Journal article, 2007)Supercritical water behaves close to that of a non-polar fluid and its ability to dissolve salt ions is very low. In rifting locations world-wide, where hot vents occur, it has been shown that seawater attains supercritical ... -
Reactive Transport of CO2 in Saline Aquifers with implicit geomechanical analysis
Kvamme, Bjørn; Liu, Shunping (Peer reviewed; Journal article, 2009)Geological storage of CO2 in saline aquifers is a promising way to reduce the concentration of the greenhouse gas in the atmosphere. Injection of CO2 will, however, lead to dissolution of minerals in regions of lowered pH ... -
Simulation of geomechanical effects of CO2 injection in cold aquifers with possibility of hydrate formation
Kvamme, Bjørn; Jemai, Khaled; Chejara, Ashok; Vafaei, Mohammad Taghi (Chapter; Peer reviewed, 2011)The injection of CO2 in saline aquifers can have a significant impact on the geochemistry and the geo-mechanics of the reservoirs. Due to this injection, minerals will dissociate in regions with low pH or precipitate in ... -
Simulation of hydrate dynamics in reservoirs
Kvamme, Bjørn; Vafaei, Mohammad Taghi; Chejara, Ashok; Jemai, Khaled (Chapter; Peer reviewed, 2011)Gas hydrates in reservoirs are generally not in thermodynamic equilibrium and there may be several competing phase transitions involving hydrate. Formation of carbon dioxide hydrates during aquifer storage of carbon dioxide ... -
Theoretical studies of CO2 hydrates formation and dissociation in cold aquifers using RetrasoCodeBright simulator
Jemai, Khaled; Kvamme, Bjørn; Vafaei, Mohammad Taghi (Peer reviewed; Journal article, 2014)Abstract: - Hydrates of CO2 and water can form during aquifer storage if the reservoir has regions where conditions of pressure and temperature are inside the hydrate forming conditions. A very common assumption is that ... -
Theoretical studies of Methane Hydrate Dissociation in porous media using RetrasoCodeBright simulator
Chejara, Ashok; Kvamme, Bjørn; Vafaei, Mohammad Taghi; Jemai, Khaled (Peer reviewed; Journal article, 2012)Methane hydrates in reservoir are generally not in chemical equilibrium, there may be several competing hydrate phase transitions like for instance hydrate dissociation due to pressure or temperature changes, hydrate ... -
Transport and storage of CO2 in natural gas hydrate reservoirs
Ersland, Geir; Husebø, Jarle; Graue, Arne; Kvamme, Bjørn (Peer reviewed; Journal article, 2009-02)Storage of CO2 in natural gas hydrate reservoirs may offer stable long term deposition of a greenhouse gas while benefiting from methane production, without requiring heat. By exposing hydrate to a thermodynamically preferred ... -
Why should we use residual thermodynamics for calculation of hydrate phase transitions?
Kvamme, Bjørn; Zhao, Jinzhou; Wei, Na; Sun, Wantong; Zarifi, Mojdeh; Saeidi, Navid; Zhou, Shouwei; Kuznetsova, Tatiana; Li, Qingping (Journal article; Peer reviewed, 2020)The formation of natural gas hydrates during processing and transport of natural has historically been one of the motivations for research on hydrates. In recent years, there has been much focus on the use of hydrate as a ...
