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 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 ... -
Stages in the dynamics of hydrate formation and consequences for design of experiments for hydrate formation in sediments
Kvamme, Bjørn; Coffin, Richard B.; Zhao, Jinzhou; Wei, Na; Zhou, Shouwei; Li, Qingping; Saeidi, Navid; Chien, Yu-Chien; Dunn-Rankin, Derek; Sun, Wantong; Zarifi, Mojdeh (Journal article; Peer reviewed, 2019)Natural gas hydrates in sediments can never reach thermodynamic equilibrium. Every section of any hydrate-filled reservoir is unique and resides in a stationary balance that depends on many factors. Fluxes of hydrocarbons ... -
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 ...
