the faster the growth of hydrate film.Compared to system pressure and temperature,the effect of droplet size and diffusion barrier on hydrate formation were much greater.The diffusion barrier in hydrate film was a major factor affecting the conversion of suspended water droplet into gas hydrate.The...
It is found that the hydrate crystal first appears at the gas–water interface where the availability of host and guest molecules are relatively high, and soon a solid layer called hydrate film or hydrate crust forms and separates the gas from water. Then the hydrate grows into the water ...
Methane hydrate is widely distributed in the pores of marine sediments or permafrost soils, contributing to their mechanical properties. Yet the tensile properties of the hydrate at pore scales remain almost completely unknown, notably the influence of g
Notes 1. The static lifetime of a raw material is the ratio of the reserves or the total resources (sum of reserves and resources) of a raw material to its annual output and corresponds to the number of years that a non-renewable raw material is globally available assuming constant consumpt...
Hydrate formation runs using MD simulation were carried out with optimal concentration of methane in water. The presence of L-histidine in the system was found to significantly enhance methane hydrate growth kinetics as compared to pure water for both experimental and MD simulation runs. Final gas ...
Crystal growthIn the present study, the effect of a polar amino acid, L-histidine on methane hydrate growth kinetics has been investigated. Methane hydrate formation experiments were carried out in a stirred tank reactor setup at pressure and temperature conditions of 274.15 K and 5.0 MPa ...
Therefore, this paper aims to investigate the kinetics of hydrate formation by predicting the relationship of growth rate of methane hydrate with temperature and pressure using ANN and ANFIS. This goal can also be achieved by solving complicated governing equations while artificial intelligence provides ...
It was established that the reduction of the supercooling at the onset of methane hydrate formation 螖To by adding methanol is statistically significant, even at low concentrations. The value of 螖To decreases by a factor of five in the transition from water to 20 mass% alcohol solution. It ...
Induction is the transport of gas from the aqueous phase and through the liquid film to the hydrate–liquid interface. Growth is the reaction of aqueous phase methane to form hydrate at the interface. A critical radius is needed for growth of the hydrate nuclei. A separate mathematical ...
