Accelerating the nucleation process nonporous materials in gas storage

The nucleation process in solid natural gas storage is one of the key steps in the storage capacity and stability under environmental conditions. The gas storage conditions can be improved by controlling this stage. In this research, we tried to use nonporous materials In order to obtain the thermal properties of nanoparticles in the stability of solid gas and use of its porosity in nanoscale dimensions to increase the storage capacity. Therefore, the use of pure and functional nanoparticle graphene into nanofluid was evaluated and the results were compared with each other. The gas solidification process was carried out at a concentration of 1% wt. of graphene at 1000 psig and 4 °C.The results were compared with a control sample containing water/surfactant and a pure water sample, and it was observed that the functionalizing process by removing surfactant would ultimately lead to better performance. Graphene itself reduced the process of dissolution by 67.2% and induction time to 71% and increased the storage value by 67%.It is also seen that the graphene nanoparticulate plays the same role in storing gas as surfactant, with the difference that it increases stability. This is while surfactant decreases this stability and increases the rate of gas dissolution.
