The performance of iodine extraction in the emulsion-flow column was evaluated using an indicator of difficulty in separation, height of transfer unit, HTU and of the number of theoretical plates, N_th. Resulting HTU values ranged from 0.15 to 0.78 m and N_th changed from 0.58 to 1.3. HTU values were formulated in accordance with operating liquid velocities. Despite a 30% margin of error, HTU values were found to be useful in predicting column performance. Observed HTU values were compared with those of conventional extraction columns with or without mechanical agitation. The emulsion-flow column meets the top-level performance of extractors without mechanical agitation, such as packed and spray columns, and performs in the middle range of agitated extractors, although these sacrifice the structure simplicity to assure stable counter-current operation. The advantage of the emulsion-flow column is better HTU values with stable counter-current operation in a simple column structure.

使用分离难度、转移单元高度、HTU和理论塔板数N _th的指标来评估乳液流动塔中碘提取的性能。由此产生的HTU值范围从 0.15 到 0.78 m，N _th从 0.58 变为 1.3。HTU值是根据操作液体速度制定的。尽管有 30% 的误差幅度，但发现HTU值可用于预测色谱柱性能。观察到的HTU值与有或没有机械搅拌的传统萃取柱的值进行比较。乳化液流塔满足无机械搅拌萃取塔的顶级性能，如填充塔和喷雾塔，在搅拌萃取塔的中等范围内发挥作用，尽管这些牺牲了结构的简单性以保证稳定的逆流操作。乳液流塔的优点是在简单的塔结构中具有更好的HTU值和稳定的逆流操作。
