In this survey, the reactive mass transfer data are determined for extraction technique in the modified rotating disc column. Mathematical models are investigated to compute the mass transfer coefficients of the dispersed phase. An increase in the dispersed phase holdup from 0.85 to 0.12 and a decrease in droplet diameter from 2.24 to 0.74 mm are observed with increasing rotation speed from 170 to 410 rpm in the optimized system. The experiments showed that the optimum transport efficiency in rotor speed of 410 rpm in this column is equal to 98.85% and 99.45% for extraction and stripping stages, respectively. The model's achievement is compared with the solvent extraction data and a significant validity is obtained by coupling the forward mixing approach (average absolute relative error lower than 13%). The mathematical modeling expresses that the axial dispersion and backflow coefficients based on the continuous phase increase by an increase in the rotor speed and inlet continuous phase rate. In contrast, these coefficients reduce at a higher inlet dispersed phase rate. High mass transfer coefficients were obtained in the stripping stage compared to the extraction stage. This report's study provides beneficial information to design solvent extraction equipment.

在这次调查中，反应传质数据被确定为改进的转盘塔中的提取技术。研究数学模型以计算分散相的传质系数。在优化的系统中，随着转速从 170 rpm 增加到 410 rpm，观察到分散相保持率从 0.85 增加到 0.12，液滴直径从 2.24 减少到 0.74 毫米。实验表明，该塔在 410 rpm 转子速度下的最佳输送效率分别等于萃取和汽提阶段的 98.85% 和 99.45%。将该模型的成果与溶剂萃取数据进行比较，通过耦合正向混合方法获得了显着的有效性（平均绝对相对误差低于13%）。数学模型表明，基于连续相的轴向扩散和回流系数随着转子速度和入口连续相速率的增加而增加。相反，这些系数在较高的入口分散相速率下降低。与萃取阶段相比，在汽提阶段获得了高传质系数。本报告的研究为设计溶剂萃取设备提供了有益的信息。
