Hydraulic and Mass-Transfer Characteristics of Raschig Super-Pak 250Y

Popis výsledku v původním jazyce

Our paper presents hydraulic, hydrodynamic and mass-transfer characteristics of the Raschig Super-Pak 250Y high-capacity structured packing measured under absorption conditions. The measurements were performed in the absorption column of inner diameter of 0.29 m using proven aqueous test systems. Measured data reveal excellent gas-phase mass-transfer performance and improved hydraulic behavior which is in agreement with the data provided by the vendor. There was found significant degree of the liquid-phase axial mixing on the packing. All six packing constants of the model proposed by Billet and Schultes (1999) were evaluated. The HETP values for distillation of C-6/C-7 and methanol/n-propanol mixtures were predicted using the BS-model with the evaluated constants and plug flow assumption. Predicted HETPs were found to be in a poor agreement with those measured under distillation conditions. However, we do not address this disagreement to fundamental impropriety of the test systems or
