利用四氢呋喃（T HF）作为热力学促进剂对水合物法回收烟道气中的CO2进行了分离实验。结果表明，温度为279．15K，压力为1．6MPa时，利用摩尔分数为6．0％ THF水溶液，进行单级水合物分离，模拟烟道气中CO2的回收率可以达到48．55％，在同一温度下，随着压力的增大，平衡气相和水合物相中CO2的摩尔组成呈现下降的趋势。之后采用气-水合物闪蒸模型计算平衡气相和水合物相中CO2的摩尔组成，并与实验值进行了比较，计算结果的精度有待进一步提高。

Tetrahydrofuran(THF) is used as thermodynamic promoter to separate CO2 from flue gas via forming hydrate . The result shows that the recovery rate of CO2 in one stage can be reached to 48 .55% in the present of 6 .0% THF solution at temperature 279 .15 K ,pressure 1 .6 MPa .In the same temperature the mole composition of CO2 is to decrease with the pressure increasing . Applying vapor-hydrate flash model to calculate CO2 mole composition of equilibrium gas phase and hydrate phase ,the result is good ,but more model work should to do for more precision calculation result .
