Study of the methane hydrates obtaining process in static conditions

We have studied the process of artificial methane hydrates obtaining in static conditions from distilled and "secondary" water (prepared by the decomposition of methane hydrate), as well as the additional metal surface using inside of cameras. It was found dependence from the type of the liquid phase and the presence/absence of additional metal surface inside the camera; in the same initial conditions of temperature and pressure, it can be obtained samples with different degrees of transformation of the "water-gas" to hydrate and various crystalline morphology.
