In this work, the mass transfer performance of a new eductor liquid–liquid extractor is investigated experimentally and modeled by dimensional analysis and response surface methodology (RSM) with the utilization of water/acetic acid/toluene system. A correlation is derived for the overall mass transfer coefficient versus the Reynolds number, throat to nozzle area ratio, projection ratio, and the two phases of flow rates ratio. Based on the obtained results, the Reynolds number is known as the most effective parameter. Also, different hydrodynamic and geometrical parameters, giving the same Sauter mean diameter, have different mass transfer coefficients due to differences in droplet size distribution. In addition, the RSM studies show that the effects of the parameters are in the order of the two phases of flow rates ratio, the venturi throat to nozzle tip distance, nozzle diameter, and venturi throat diameter. The maximum overall mass transfer coefficient obtained equals to 0.000278 m/s for the studied system.

喷射器液-液萃取器中的传质研究：尺寸分析和响应面方法建模

在这项工作中，对新型喷射器液-液萃取器的传质性能进行了实验研究，并利用水/乙酸/甲苯系统，通过尺寸分析和响应面方法（RSM）对其进行了建模。得出了总传质系数与雷诺数，喉管与喷嘴面积之比，投影比以及流速两相之比的相关性。根据获得的结果，雷诺数被认为是最有效的参数。同样，由于液滴尺寸分布的差异，给出相同索特平均直径的不同流体动力学和几何参数具有不同的传质系数。此外，RSM研究表明，参数的影响按流量比率的两个阶段的顺序排列，文丘里喉管到喷嘴尖端的距离，喷嘴直径和文丘里喉管直径。对于所研究的系统，获得的最大总传质系数等于0.000278 m / s。
