摘　　要：从烟气中捕集CO_(2)是碳减排的主要手段。超重力技术利用离心力场的强大驱动力,获得极大的微液界面,能显著加速CO_(2)在液相的传递和反应效率,实现分离过程强化;同时,还能大幅减小设备体积,使之适用于撬装。因此,开展了中试规模超重力旋转填料床对工业烟气中CO_(2)的吸收试验,对超重力塔的脱碳效率以及吸收温度、贫液循环量、气液比等关键工艺参数的影响进行了评估。该技术对能源密集型的撬装碳捕集单元具有广阔的应用前景。Capturing CO_(2) from flue gas is the main means of carbon emission reduction.Supergravity technology utilizes the powerful driving force of centrifugal force field to obtain a large micro-liquid interface,which can significantly accelerate the transfer and reaction efficiency of CO_(2) in the liquid phase,and realize separation process intensification.At the same time,the volume flow rate of equipment is greatly reduced,making it suitable for skid-mounted equipment.Therefore,in this paper,the absorption experiments of CO_(2) in industrial flue gas by an industrial-scale high gravity rotating packed bed were carried out,where the decarbonization efficiency of the supergravity absorption tower were investigated,as well as the influences of key process parameters such as absorption temperature,lean liquid circulation rate,gas-liquid ratio,etc.on decarbonization efficiency.This technology shows great application prospects for energy-intensive modular carbon capture unit processes.
