By employing a specific particle interaction theory and high-precision equation of states for the liquid vapor phases H2, respectively, new H2 solubility model in pure water aqueous NaCl solutions is proposed this study. The established by fitting experimental data can be used to estimate at temperatures pressures 273.15–423.15 K 0–1100 bar, salt (NaCl concentration = 0–5 mol/kg) 273.15–373.15 0–230 respectively. adopting electrolyte solutions, also predict seawater without system. Within or...

Abstract Sedimentation and burial rate can vary considerably at continental slopes, due to constantly changing tectonic processes on the geological timescale. This variation may affect transport of methane in sediment, as manifested change pore water flux, methanogenesis, diffusion hydrate removal from stability zone (HSZ) further accumulation submarine sediments. Most previous models assumed a constant sedimentation thus result inaccurate estimates total amount within HSZ. In this study, we...

Abiotic methane (CH 4 ) and hydrogen (H 2 ), which are produced during marine serpentinization, provide abundant gas source for hydrate formation on ocean floor. However, previous models of CH –H have generally focused pure water environments not considered the effects salinity. In this study, van der Waals–Platteeuw model, salinity chemical potentials , H O, was applied in a serpentinization environment. The model uses an empirical formula Peng–Robinson equation state to calculate Langmuir...

The lack of the quantification deep dissolved methane flux prevents us from accurately understanding hydrate accumulation and distribution at a given geologic setting where vertically upward advection dominates system. was usually applied as an assumed value in many previous studies. Considering changes concentration pore water further affects phase transfer between gas aqueous phases depending on situ concentration, we link bubbles to flux. Here, constructed numerical model quantify depth...
