A temperature-based measurement setup for distillation processes in rotating packed beds (RPBs) was used to investigate the overall separation performance, as well as the individual contribution of different zones to the overall performance for two chemical systems and four different packing dimensions. It was found that the local separation performance is not affected by varying the packing height or radial packing length but depends on the chemical system studied. Using the experimental setup, 2 to 7 number of transfer units (NTUs) within the packing could be achieved by varying the throughput and rotational speed. Furthermore, the experimental setup was redesigned to evaluate exclusively the separation performance of the casing, resulting in a number of theoretical stages of about N_th = 0.86. The separation performance of the casing can be used to determine the composition of the fluids entering and leaving the packing.

旋转填充床蒸馏过程的局部分离性能：可转移性和适用性

使用基于温度的旋转填充床 (RPB) 蒸馏过程测量装置来研究两个化学系统和四种不同填料尺寸的整体分离性能，以及不同区域对整体性能的单独贡献。研究发现，局部分离性能不受改变填料高度或径向填料长度的影响，而是取决于所研究的化学系统。使用实验装置，通过改变吞吐量和旋转速度，可以在填料内实现 2 至 7 个传输单元 (NTU)。此外，重新设计了实验装置，以专门评估套管的分离性能，从而产生约N _th = 0.86 的多个理论阶段。套管的分离性能可用于确定进入和离开填料的流体的成分。
