Abstract:An experiment with methane hydrate formation from ice powders was conducted through the gas consumption method (PVT system) to corroborate the existing phenomenological multistage kinetic model. The influence of temperature, pressure and ice gram size on hydrate formation was experimented and analyzed. Lower temperature can enhance the hydrate formation. At the temperature up to nearly the melting point of ice, the excess pressure dominatly influenced the rate of methane hydrate formation. The smaller grain size of the ice powder can promote the methane hydrate formation. The lower rate of pressurization has good effect on the pressure drop process. (C) 2014 Published by Elsevier Ltd.
