Abstract

Abstract: 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.

摘要： 利用四氢呋喃( THF) 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2 7 9. 1 5K, 压力为1. 6MP a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4 8. 5 5%, 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。之后采用气灢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。
