摘　　要：实验探究了CO2水合物法淡化海水的影响因素。在模拟海水的盐水溶液中进行水合物反应,分解后测出溶液前后盐度的变化,分析了压力、温度以及溶液的盐度等因素对淡化效果的影响。由结果分析可知,水合物分解后的水溶液盐度有一定降低,采用CO2水合物法可以实现海水淡化的目的,温度越低,压力越高,淡化效果越好,CO2水合淡化合适压力在4～5 MPa,合适温度2～3℃,可以逐级对海水盐溶液进行水合淡化,以达到要求的淡化效果,用合理的淡化流程来达到好的淡化效益。Explores the CO2 hydrate desalination experiment, which runs the hydrate reaction in the simulated seawater. Measures the salinity changes of hydrate decomposition＇ s solution and analyzes the effect of the pressure, temperature and salinity of water solution to desalt factors. The result shows that the salinity of decomposition water solution has significantly reduce, and the CO2 hydrate method can achieve the purpose of the sea water desalination. The optimal pressure is 4 - 5 MPa. The optimal temperature is 2 - 3 ℃. And it can meet the requirement to desalt the salt solution progressively. The reasonable desalination process achieves a reasonable benefit.
