与使用中试工厂实验的传统设计方法相比，基于实验室实验和适当模拟工具的信息设计提取柱可以减少时间和成本。为此目的，在实验室规模的实验中研究液滴和液滴群的行为，以便创建包含系统特定参数的数学模型，这些参数必须适合于这些实验。这些模型是在一个模拟程序中实现的，该程序解决了萃取柱中的落-人口平衡。在亚琛工业大学的avt -热过程工程中，这个概念在ReDrop项目中得到了实施。ReDrop可以预测标准体系和技术体系中脉冲筛塔板、结构萃取塔和随机填充萃取塔的分离性能和泛点。该方案已成功地扩展到具有旋转内部的柱。
The design of extraction columns based on information from lab experiments and appropriate simulation tools allows reduction of time and costs compared to conventional design methods using pilot-plant experiments. For this purpose, the behavior of drops and drop swarms is investigated in lab-scale experiments in order to create mathematical models containing system-specific parameters that have to be fitted to those experiments. These models are implemented in a simulation program that solves drop-population balances in extraction columns. At AVT-Thermal Process Engineering of the RWTH Aachen University this concept was implemented in the program ReDrop. ReDrop can predict the separation performance and flooding point of pulsed sieve tray and structured as well as random-packing extraction columns for standard and technical systems. The program has successfully been extended to columns with rotating internals.
