Liquid–liquid mass transfer performance in a capillary microreactor system was studied with an improved experimental method. Proper sampling modes were chosen to eliminate the effect of the sampling zone on the mass transfer characterization in capillary microreactor systems. The overall volumetric mass transfer coefficients in the T-micromixer and the capillary microreactor system were found to smoothly increase and then significantly increase with increasing the Reynolds number of two immiscible liquid phases. Other factors such as the inlet mode and inner diameter of T-micromixer, the capillary length, and the volumetric flux ratio of the aqueous phase to the organic phase affected the mass transfer performance in the T-micromixer and the capillary microreactor system. Furthermore, the contribution of the mass transfer in the T-micromixer zone to the capillary microreactor system was found to be in a range of 34–78% under the involved experimental conditions, which was emphasized in the proposed empirical correlations. © 2017 American Institute of Chemical Engineers AIChE J, 2017

毛细管微反应器系统中液-液传质性能的表征

用改进的实验方法研究了毛细管微反应器系统中的液体-液体传质性能。选择适当的采样模式以消除采样区对毛细管微反应器系统中传质表征的影响。发现在T型微混合器和毛细管微反应器系统中，总的体积传质系数随着两个不可混溶液相的雷诺数的增加而平稳地增加，然后显着增加。其他因素，例如T型微混合器的入口模式和内径，毛细管长度以及水相与有机相的体积通量比，会影响T型微混合器和毛细管微反应器系统中的传质性能。此外，在所涉及的实验条件下，发现在T型微混合器区域传质对毛细管微反应器系统的贡献在34％至78％的范围内，这一点在所提出的经验相关性中得到了强调。©2017美国化学工程师学会AIChE的Ĵ，2017年
