The overall goal of this research project is to represent the mass transfer dynamics of an industrial packed column on the basis of miniaturised experimental set-ups and an appropriate modelling. The miniaturised experimental set-up is to constitute the smallest feasible separation unit that allows conclusions on the mass transfer efficiency of industrial columns with consideration of the real boundary conditions. In this manner no longer a laboratory column shall be used as a laboratory basis for the design of industrial columns which principally is an extremely reduced representation of an industrial apparatus. The approach proposed here therefore represents a fundamental paradigmatic change in the industrial and scientific common practice and needs to be profoundly investigated. The dynamics of a packed column can be subdivided into fluid mechanic aspects and mass transfer characteristics. This project is a first step where the fluid dynamic behaviour of the packing is to be characterised according to the overall methodologic concept. Later in a subsequent investigation project - based on the fluid dynamic results - consequently an extension by the mass transfer behavior has to take place. With the development of the afore-described miniaturized experimental set-up a new technology platform would be created within thermal separation engineering, which allows the decided adjustment, observation and determination of different parameters (mass transport resistances, contact angles, surface structures, etc.) and therefore perspectively is of utmost interest even beyond the mere scope of scale-up problems.

本研究项目的总体目标是代表工业填料塔的传质动力学的基础上，简化的实验装置和适当的建模。简化的实验装置是构成最小的可行分离单元，其允许在考虑真实的边界条件的情况下对工业柱的传质效率得出结论。在这种情况下，实验室色谱柱不得再用作工业色谱柱设计的实验室基础，因为工业色谱柱主要是工业仪器的极简化代表。因此，这里提出的方法代表了工业和科学共同实践的根本范式变化，需要深入研究。填料塔的动力学可以细分为流体力学方面和传质特性。该项目是第一步，填料的流体动力学行为将根据整体方法概念进行表征。随后在随后的研究项目中-基于流体动力学结果-因此必须进行传质行为的扩展。随着上述小型化实验装置的发展，将在热分离工程中创建一个新的技术平台，该平台允许对不同参数（传质阻力、接触角、表面结构等）进行决定性的调整、观察和确定。因此，即使超出了规模扩大问题的范围，Permande也是最令人感兴趣的。
