Agitated‐pulsed column (APC) is a newly designed extraction column with excellent mass transfer performance. In this work, Sauter mean drop diameter d ₃₂ and drop size distribution was investigated under different operation conditions in a 25 mm diameter APC. The results show that with an increase in pulsation intensity and agitation speed the drop size distribution is narrowed and d ₃₂ is decreased significantly. With increasing dispersed‐phase velocity, d ₃₂ increased and drop size distribution become narrow, while there was no noticeable change with continuous velocity. The cumulative size distribution was found to be predicted well using the Inverse Gaussian function. A new correlation was proposed to predict the experimental d ₃₂ data of the APC column used in this study. Furthermore, population balance model was applied to predict the drop size distribution with refitted parameters in the breakage, coalescence kernels functions.

搅拌脉冲溶剂萃取塔的液滴尺寸相关性和总体平衡模型

搅拌脉冲塔（APC）是一种新设计的萃取塔，具有出色的传质性能。在这项工作中，在直径为25 mm的APC中，在不同的操作条件下研究了Sauter的平均墨滴直径d ₃₂和墨滴大小分布。结果表明，随着脉动强度和搅拌速度的增加，液滴尺寸分布变窄，d ₃₂显着减小。随着分散相速度的增加，d ₃₂增加，液滴尺寸分布变窄，而连续速度没有明显变化。发现使用逆高斯函数可以很好地预测累积大小分布。提出了一种新的相关性，以预测本研究中使用的APC色谱柱的实验d ₃₂数据。此外，使用种群平衡模型来预测破损，合并核函数中具有重新拟合参数的液滴大小分布。
