Mass transfer and liquid hold-up determination in structured packing by CFD

Comaprison of Mass-Transfer Efficiencies of Scc and Structured Packing

In a previous paper, pressure drop, flooding and mass-transfer characteristics of a novel pilot-scale distillation column called spinning cone column (SCC) were presented. Here, we present the result of comparison of mass-transfer efficiencies of SCC and structured packing. Comparison of SCC and structured packing mass-transfer characteristics show that the gas and liquid-side height of transfe...

Vapour–liquid Mass Transfer Performance of Modular Catalytic Structured Packing

The mass transfer performance the Katapakw-SP has been evaluated experimentally and the Delft MCSP model, a parallel channel model is developed to predict the HETP as function of F-factor. Pilot scale (i.d. 450 mm) total reflux distillation experiments were done with an aqueous system Methanol/Water and organic system Cyclohexane/n-Heptane. With the latter, two types of Katapak-SP were tested. ...

CFD Simulations of Pressure Drop in KATAPAK-S Structured Packing

KATAPAK-S is a type of structured catalytic packing, which is used in reactive distillation processes. The dry pressure drop characteristic (the pressure drop in the absence of liquid flow) is of significant importance for the investigation of process hydrodynamics. In this paper, the dry pressure drop within the catalyst packed channels of KATAPAK-S has been investigated using Computational Fl...

Investigation of Packing Effect on Mass Transfer Coefficient in a Single Drop Liquid Extraction Column

Mass transfer performance of modular catalytic structured packing

A mechanistic, parallel channel model was developed and validated experimentally to enable the prediction of mass transfer performance of the Katapak-SP, a novel, modular catalytic structured packing. Total reflux distillation experiments were carried out at atmospheric pressure in a column with internal diameter of 0.45 m, using aqueous (Methanol/Water) and organic (Cyclohexane/n-Heptane) test...
