摘要:
水合物法捕获CO2具有储气密度大、分离精度高等优点。为解决水合物法捕获CO2技术面临的反应速率慢等难题,实验研究了生物表面活性剂RL4型鼠李糖脂、混合型鼠李糖脂及离子液体[PIPS]DBSA对CO2水合物生成相平衡压力、气体消耗量的影响规律。结果表明,上述试剂对CO2水合物相平衡压力的影响受到温度及浓度的双重作用。RL4型鼠李糖脂、混合型鼠李糖脂和离子液体[PIPS]DBSA降低CO2水合物相平衡压力最大幅度分别为15.8%,18.9%,14.3%,促进CO2水合物生成最佳质量比均为500 mg/kg。最后,计算了不同温度下各个最佳浓度化学试剂体系的CO2消耗量,发现RL4型鼠李糖脂、混合型鼠李糖脂和离子液体[PIPS]DBSA均可有效增加水合物生成时的CO2消耗量,且温度为279 K时,各体系下气体消耗量增加效果最好,效果最佳的鼠李糖脂(混合型)溶液的增加幅度达到了37.7%,平均增幅为25.3%。
Abstract:
The CO2 capture of hydrate method has the advantages of high storage density and high separation accuracy. In order to solve the problem of slow reaction rate of the CO2 hydrate for the capture technology, the effect on CO2 hydrate formation phase equilibrium pressure and gas consumption of bio-surfactant RL4 type rhamnolipid, hybrid rhamnolipid and ionic liquid [PIPS]DBSA were studied experimentally in a high pressure reaction kettle device. The results showed that the CO2 hydrate formation strengthened by rhamnolipid is influenced by temperature and concentration. The phase equilibrium pressure of hydrate formation in presence of RL4 type rhamnolipid, hybrid rhamnolipid and ionic liquid [PIPS]DBSA were decreased by 15.8%, 18.9%, 14.3% respectively. And their optimum concentration was 500mg/kg. At last, CO2 gas consumptions in their optimum concentration system were also calculated. And the RL4 rhamnolipid, hybrid rhamnolipid and ionic liquid [PIPS]DBSA can effectively increase the gas consumption of CO2 hydrate formation, and at the temperature of 279 K, the gas consumption increased most. Especially, the hybrid rhamnolipid solution increased by 37.7%, with an average increase of 25.3%.
