The main objective of the proposed renewal project is the finalization of the comprehensive model for the description of columns with sandwich packings using the rate-based modelling approach. Key aspects of the project are the experimental determination of regime-specific dispersion coefficients, liquid phase residence times and liquid-side mass transfer coefficients as well as their implementation in the model. Additionally, a correct determination of the flooding points based on a phenomenological description of the flooding as well as an upgrade of correlations for the prediction of hydrodynamic parameters to account for variable fluid properties will be addressed. The required experimental data will be obtained via ultrafast X-ray tomography. For an overall assessment of the performance of sandwich packings in comparison with conventional packing internals, both chemical absorption processes and distillation processes will be analysed with the finalized model.

拟议更新项目的主要目标是使用基于速率的建模方法，最后确定用于描述夹层填料塔的综合模型。该项目的关键方面是特定的制度的分散系数，液相停留时间和液体侧传质系数的实验测定，以及它们在模型中的实施。此外，一个正确的确定的泛点的基础上的现象学描述的洪水，以及升级的相关性预测的流体动力学参数，以考虑到可变的流体性质将得到解决。所需的实验数据将通过超快X射线断层扫描获得。为了全面评估夹层填料与传统填料内部构件相比的性能，将用最终模型分析化学吸收过程和蒸馏过程。
