Research is underway to develop an optical laser probe to measure drop size distributions and velocities in two-phase extraction systems. These measurements will be used ultimately to determine the effect of extraction column operating conditions on the spatial variations of the drop size, drop velocity, and column hold-up in extraction columns of different diameters and different internal mixing devices. Of particular interest will be the assessment of the effect of scale-up on the degree of dispersed phase backmixing and bypassing in various types of commercial columns. A computer code for the prediction of the flow patterns, turbulence characteristics, and the local droplet breakage and coalescence rates in the individual stage of an extraction unit also will be developed.

正在研究开发一种光学激光探头来测量两相萃取系统中的液滴尺寸分布和速度。这些测量将最终用于确定萃取塔操作条件对不同直径和不同内混合装置的萃取柱中液滴尺寸、液滴速度和柱含率的空间变化的影响。特别令人感兴趣的是评估放大对各种类型商业塔中分散相返混和绕过程度的影响。还将开发一种计算机程序，用于预测萃取装置各个阶段的流型、湍流特性以及局部液滴破碎和聚结率。
