Experimental analysis of the liquid hold-up contributions in catalytic packing Katapak-SP

Knowledge of liquid hold-up is essential for understanding reactive distillation column performances and develop fundamental models of packing behaviour. The modular structure of Katapak-SP, the novel family of catalytic structured packings manufactured by Sulzer Chemtech, provides a high degree of flexibility in process applications but complicates the design and the inner flows distribution. Therefore, for this type of packing the estimation of the different liquid hold-up contributions is a challenging task. The present investigation has focused attention on the experimental determination of this key parameter.
