Liquid–liquid mass transfer performance of a novel pore‐array intensified tube‐in‐tube microchannel (PA‐TMC) was investigated with the water‐benzoic acid‐kerosene system. Both mass transfer efficiency (E) and volumetric mass transfer coefficient (K _La) are found to increase simultaneously with the flow rate, but decrease with total number of pores and rows. However, E increases but K _La decreases with the annular length. In particular, the pore size shows an optimal value at 0.3 mm due to the interplay problem of the radial adjacent pores. Computational fluid dynamics simulations reveal that the high kinetic energy generated by the pore‐array section plays a significant role in mass transfer process. The artificial neural network model is established to correlate K _La with the investigated parameters of PA‐TMC. The comparison of K _La with other types of contactors indicates that PA‐TMC has superior mass transfer performance and high throughput for a broad industrial application.

新型孔阵列增强管中微通道中液-液传质性能的表征

使用水-苯甲酸-煤油系统研究了新型孔阵列增强的管中管微通道（PA-TMC）的液-液传质性能。发现传质效率（E）和体积传质系数（K _L a）随流速同时增加，但随孔和排的总数而降低。但是，E增加，但K _L a 随环形长度的增加而减小。特别地，由于径向相邻孔的相互作用问题，孔尺寸在0.3mm处显示最佳值。计算流体动力学模拟表明，孔阵列截面产生的高动能在传质过程中起着重要作用。建立了人工神经网络模型以使K _L a与PA-TMC的研究参数相关。将K _L a与其他类型的接触器进行比较表明，PA‐TMC具有出色的传质性能和高通量，适用于广泛的工业应用。
