Investigation of the effect of Zinc Oxide Nano-particles and Cationic Surfactants on Carbon Dioxide Storage capacity

One of the methods of removing, storing, recovering or transferring carbon dioxide (as one of the greenhouse gases) is the use of hydrate formation. In this study, the effect of the presence of zinc oxide nanoparticles and steel trimethyl ammonium bromide (CTAB) surfactant on the amount of mol consumed and carbon dioxide storage capacity between carbon dioxide hydrate and water at different temperatures, pressures and concentrations of the solution was investigated. For this purpose, a laboratory system was developed to perform hydrate formation experiments. Experiments were performed in the pressure range of 20 to 30 bar, temperature range from 275 to 279 degrees Kelvin. Experimental results (for mole consumption and storage capacity) showed that with increasing pressure at constant temperature for pure water, the amount of mole consumed increased and storage capacity increased by 15%. With decreasing temperature at constant pressure (20 bar), the amount of mol consumed increased by 17% and the storage capacity by 19%. Addition of zinc oxide by 0.05 wt% at constant temperature and pressure increased the amount of mol consumed by 14% and storage capacity by 13%. And 0.1% by weight of zinc oxide increases the amount of mol consumed and storage capacity by 26% and 22%, respectively
