摘要 为深入研究CO2开发CH4水合物对环境的影响,从而实现长期储存CO2和开发新能源CH4水合物的目的。本研究主要考察了不同温度下(1—7℃),CH4+CO2混合气在纯水和NaCl溶液(质量分数3.6%)中的生成水合物时的溶解相平衡。考察了温度和盐对溶解相平衡的影响。并将实验值与Chen-Guo水合物模型计算值进行了比较。实验测量不同温度下CH4+CO2混合物气在纯水和NaCl盐水体系的生成水合物的相平衡压力。还首次测量了水合物存在条件下,水相中CO2和CH4的溶解度,为研究CO2置换法开采CH4水合物对海洋环境的影响提供必要的基础数据。 In order to deeply research the influence of developing CO2 to CH4 hydrate on environment for long-term storing CO2 and developing CH4 hydrate as new energy resource,the dissolved phase equilibrium of the hydrate at different temperatures(1-7 ℃) was mainly investigated,which is produced by CH4+CO2 mixture gas in pure water and NaCl solution(mass fraction 3.6%).The effects of temperature and salt on the dissolved phase equilibrium were studied.The experimental data and predicted data by Chen-Guo hydrate model were compared.The phase equilibrium pressures of hydrate formed by CH4+CO2 gas mixture in pure water and NaCl solution were measured at different temperatures.The solubility of CO2 and CH4 in water phase in the presence of hydrate was measured for the first time.This research can provide basic data for the study of CO2 replacing method for CH4 production and its influence on marine environment.
