The methane hydrate dissociation at an external pressure of 1 bar has been experimentally studied. The methane dissociation rate depends on the heat transfer intensity in the course of dissociation. Quasi-isothermal and nonisothermal conditions of clathrate dissociation have been compared. Under non...
The kinetics of methane hydrate decomposition was studied using sapphire cell apparatus at constant pressure.The effect of dissociation temperature ranging from 245.15 to 271.15 K,formation pressure ranging from 5.5 to 7.0 MPa,freezing time and stirring on the dissociaton percentages of methane hydrate...
Kinetics of methane hydrate formation with different ratio of silica sand & clay and different water saturations were studied. At suitable temperature and ... MA Kumar,MT Sakpal,S Roy,... 被引量: 19发表: 2014年 Methane Hydrate Formation and Dissociation in the Presence of Bentonite Clay Suspe...
First, the effects of initial pressure and three surfactants (sodium dodecyl sulfate (SDS), dodecyltrimethyl ammonium bromide (DTAB) and Triton X-100 (TX-100)) and two thermodynamic additives (tetrahydrofuran (THF) and tetra butyl ammonium bromide (TBAB)) on methane hydrate formation kinetics ...

the decomposition processes of synthetic methane hydrates,ethane hydrates,normal butane-nitrogen hydrates and mixed gas hydrates are similar,and the pressures of the decomposing gases appear monotonically increasing at vacuum condition;however,during the dissociation processes of synthetic methane gas hydrates...
Kinetics of the Formation and Dissociation of Gas Hydrates from CO2-CH4 Mixtures Sequestration of carbon dioxide (CO 2) in the form of its hydrates in natural methane (CH 4) hydrate reservoirs, via CO 2/CH 4 exchange, is an attractive p... K Horvat,P Kerkar,K Jones,... - 《Energies...
One proposed method to recover methane from marine natural gas hydrates is to sequester carbon dioxide (CO2) as hydrates and produce methane. Fundamental understanding of CO2 hydrate in marine environments – the formation and dissociation behavior needs to be understood first in order to develop ...
Heat Transfer Analysis of Methane Hydrate Sediment Dissociation in a Closed Reactor by a Thermal Method The heat transfer analysis of hydrate-bearing sediment involved phase changes is one of the key requirements of gas hydrate exploitation techniques. In thi... J Zhao,C Cheng,Y Song,... - 《...
Kinetics and Mechanisms of Gas Hydrate Formation and Dissociation with Inhibitors A bstract : A common chemical used in petroleum industry for preventing hydrates is methanol. Other alcohols and glycols (thermodynamic inhibitors) can also be used to shift hydrate formation to lower temperatures and ...
