Modeling of Hydrate Formation Using Irregular Pore Network Model

Hydrate formation in porous media is one of the novel methods used in natural gas storage and handling. Using catalysts and other porous media need to investigate hydrate formation and dissociation in these media whose incentives root back to existing huge reservoirs of natural gas. Such a method is challenging in various aspects particularly for cases in which optimum structure of the porous media is sought. On the other hand, to obtain the optimum structure of porous media requires a model to depict appropriate hydrate formation dynamic behavior in the porous media. One of the new modeling techniques used to model the structure of porous media is pore network modeling. This approach has an emerging application in various disciplines. In this procedure, the void space of porous media is represented by a network of pores connected by throats. In this study, an irregular network model is generated to model hydrate formation in the porous media. The dynamic behavior of hydrate formed at various pressures beyond the corresponding threshold and its interaction with pore size distribution, effective porosity and temperature have been studied.
