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 °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.

有/无磁场下氯化钠水溶液对水合二氧化碳动力学参数影响的实验研究

这项研究的主要目的是通过实验来阐明在有无磁场的情况下,去离子水和氯化钠溶液中二氧化碳在水合物中的形成情况,以了解二氧化碳对环境和气候的不良影响。实验测试是在平衡池中进行的,初始压力为30.5和35.5 bar,温度为0、2和4°C,且水中氯化钠的浓度为0-5 wt%。另外,检查了氯化钠浓度,温度,压力和磁场对气体水合物动力学参数的影响,包括气体消耗量,诱导时间和水合物形成过程中的压降。从结果明显看出,将氯化钠水溶液的浓度从1wt%改变为3wt%,导致诱导时间增加,因此显着降低了气体消耗速率和压降。结果还表明,将氯化钠水溶液从3wt%改变为5wt%对诱导时间,气体消耗和压降有轻微影响。此外,已经观察到,具有550高斯强度的磁场的存在对二氧化碳水合物形成的动力学没有显着影响。耗气量和压降。此外,已经观察到,具有550高斯强度的磁场的存在对二氧化碳水合物形成的动力学没有显着影响。耗气量和压降。此外,已经观察到,具有550高斯强度的磁场的存在对二氧化碳水合物形成的动力学没有显着影响。
