A Fugacity Approach for Prediction of Phase Equilibria of Methane Clathrate Hydrate in Structure H
In this communication, a thermodynamic model is presented to predict the dissociation conditions of structure H (sH) clathrate hydrates with methane as help gas. This approach is an extension of the Klauda and Sandler fugacity model (2000) for prediction of phase boundaries of sI and sII clathrate hydrates. The phase behavior of the water and hydrocarbon system is modeled using the Peng-Robinso...
متن کاملMethane Flux and Authigenic Carbonate in Shallow Sediments Overlying Methane Hydrate Bearing Strata in Alaminos Canyon, Gulf of Mexico
In June 2007 sediment cores were collected in Alaminos Canyon, Gulf of Mexico across a series of seismic data profiles indicating rapid transitions between the presence of methane hydrates and vertical gas flux. Vertical profiles of dissolved sulfate, chloride, calcium, magnesium, and dissolved inorganic carbon (DIC) concentrations in porewaters, headspace methane, and solid phase carbonate con...
متن کاملMolecular dynamics simulations of properties of a (001) methane clathrate hydrate surface
The results of molecular dynamics simulations of a (001) methane clathrate hydrate surface interfaced with methane gas involving 2944 water and 512 methane molecules are reported for a temperature of 270 K. The water–water, water–methane and methane– methane interactions are evaluated using the flexible potential KKY. The program MXDORTO was used for the MD calculations and a newly developed co...
متن کاملSelective occupancy of methane by cage symmetry in TBAB ionic clathrate hydrate.
Methane trapped in the two distinct dodecahedral cages of the ionic clathrate hydrate of TBAB was studied by single crystal XRD and MD simulation. The relative CH4 occupancies over the cage types were opposite to those of CO2, which illustrates the interplay between the cage symmetry and guest shape and dynamics, and thus the gas selectivity.
متن کاملthe effects of integrating cooperative learning into vocabulary learning of elementary school students
the purpose of the research is to examine if integrating cooperative learning into vocabulary learning helps to increase word recognition of students in an elementary school in iran. it tries to investigate whether cooperative learning approach enables students to improve their language learning. this research used stad (students team achievement division) as a cooperative model in this study. ...
