Abstract:Methane hydrate formation from ice powders is a complicated process, and is affected easily by many factors. In this paper, a series of experiments were conducted to study the influence of porous media's particle size and volume proportion on the hydrate formation process. An experimental system based on PVT method was used to measure the gas consumption and the pressure change through the whole process of reaction. The pressure drop and hydrate saturation were analyzed to show the effects of porous media. The results indicated that porous media not only can improve the discrete degree of ice particles, but also increase the contact area of quasi liquid layer and methane gas. The specific effects of particle size and volume proportion were based on the two effects above. (C) 2017 The Authors. Published by Elsevier Ltd.
