摘要
通过介绍气体水合物的晶体结构,从热力学方面论证了利用CO2开采海底天然气水合物的可行性,并分析了铠甲效应、温度、压力、晶体结构、晶穴充满度、多孔介质、盐度、添加剂及乳化等多种因素对CO2与CH4水合物置换反应的影响,最后指出今后研究的重点应为采取各种措施强化反应过程。该研究成果为CO2封存和海底天然气开采研究提供了一种新思路。
This paper introduced the crystal structure of gas hydrate, discussed the feasibility on methane hydrate exploitation with CO2 from thermodynamics, and analyzed the effects of different factors on the replacement reaction, including loricae effect, temperature, pressure, crystal structure, crystal cage fill fraction, porous media, salinity, additive and microemulsion. It is pointed out that reinforcement of the reaction procedure by multi measures is the research emphasis in the future, and the research provides a new thought for CO2 subsea preservation and natural gas hydrate expoitation.
