pdf Investigation of the natural gas hydrates formation in the systems "stratum water - porous medium - polymer solution" according to the data of differential thermal analysis
The article presents the results of studies of thermodynamic and kinetic characteristics of the natural gas hydrates formation in the systems "stratum water - porous medium - polymer solution". Commercially available polymer samples were used in the experiments: polyacrylamide, sodium carboxymethyl cellulose and polyethylene glycol. A solution of calcium chloride with a concentration of 400 g/l served as a model of stratum water, and quartz monodispersed sand was used as a porous medium. It has been established that the calcium chloride solution has a significant effect on the process of the natural gas hydrates formation. It is shown that in all studied systems, except for the models containing the sodium carboxymethyl cellulose solution, the addition of the calcium chloride solution leads to an increase of the supercooling degree of these systems, and there is a direct dependence between the supercooling degree and the concentration of the calcium chloride. The calculation of the kinetic parameters of the hydrate formation in the studied systems showed that the degree of water conversion into hydrate and the rate of hydrate formation are significantly reduced even at low concentrations of calcium chloride.

Keywords: natural gas hydrates, polymer solutions, porous media, calcium chloride solution.
