摘要：通过实验室填料塔研究了加压下(0. 2—0. 6MPa)哌嗪 (PZ)混合N 甲基二乙醇胺 (MDEA)水溶液吸收CO2的动力学。研究结果表明当CO2 分压大于 0. 1MPa时,压力会强化在气液界面的表面扰动,使得CO2 吸收速率较常压模型值大,并且该速率随压力的增大而增加。得到了哌嗪混合MDEA水溶液脱碳常压动力学模型的压力修正式。
The kinetics of carbon dioxide Absorption into MDEA aqueous solution blended with piperazine (PZ) (under) pressurized condition was studied in an experimental packed column. The results indicated that the (Absorption) rate of carbon dioxide under pressurized condition was higher than that of calculation value from the (kinetics) model under atmospheric pressure because the Marangoni effect was strengthened by boosting. The pressure modified (model) to the kinetics model of atmospheric pressure was obtained.
