CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishReactive distillation is one of the most attractive and popular reaction-separation units nowadays used in the CPI. The hydrodynamic properties of a novel family of catalytic structured packings (KATAPAK®-SP) were modeled using a modified version of a hydraulic model originally proposed by Hoffmann et al. for MULTIPAK®. Modifications to the model included the adaptation of a more suitable liquid holdup correlation for the open channels, and the use of a different split factor for the liquid flowing through the catalyst bags and the open channels. The use of a more suitable liquid holdup correlation for the open channels in combination with a liquid split factor dependent on liquid load gave improved pressure-drop representations below the load point of the catalyst bags. For all liquid loads, the modified model represented well the observed pressure drop data for both KATAPAK-SP packings below their gas loading points
