水合物法分离CO2研究

混合气体在形成水合物时,水合物内的气体组分与气相内不同。CO2溶解度远高于N2、O2、H2等气体,因此水合物法可分离燃煤电厂烟气中的CO2。分析了气体组成、压力、温度、促进剂和多孔介质等因素对水合物法分离CO2的影响,指出采用耦合技术降低操作压力和提高水合速度是今后改进和努力的方向。

Study on hydrate process of CO_2 separation

When hydrate is formed by mixed gas,the gas composition in hydrate is different from the original gas.CO2 solubility is far bigger than N2,O2 and H2,so CO2 can be separated from the flue gas in PC power plant by hydrate process,and the cost of this process is anticipated can be 45% lower than other method such as absorption process.The gas composition,pressure,temperature,promoter and pore materials are all analyzed from the influence to hydrate process of CO2 separation.The future research emphasis is lowe...
