Experimental study of sodium chloride aqueous solution effect on the kinetic parameters of carbon dioxide hydrate formation in the presence/absence of magnetic field

The main purpose of this study is to experimentally elucidate the hydrate formation of carbon dioxide in both of deionized water and sodium chloride solution in the presence and absence of the magnetic field with regard to bad and harmful influence of carbon dioxide on the environment and climate. The experimental tests were performed in the equilibrium cell at the initial pressures of 30.5 and 35.5 bar and temperatures of 0, 2 and 4 degrees C with different concentrations of sodium chloride in water 0-5 wt%. Additionally, the effect of sodium chloride concentration, temperature, pressure and magnetic field on the gas hydrate kinetic parameters including the amount of gas consumption, induction time and pressure drop during the hydrate formation were examined. It is evident from the results that changing the concentration of sodium chloride aqueous solution from 1 to 3 wt%, leads to increase the induction time and hence considerably decreases the gas consumption rate and pressure drop. The results were also shown that changing the sodium chloride aqueous solution from 3 to 5 wt% has a slight effect on the induction time, gas consumption and pressure drop. Moreover, it was observed that the presence of magnetic field with 550 gauss strength has no considerable effect on the kinetic of carbon dioxide hydrate formation.
