Type of packings and characteristics of their geometry can affect the flow behavior in the reactive distillation columns. KATAPAK SP is one the newest modular catalytic structured packings (MCSP) that has been used in the reactive distillation columns, recently. However, there is not any study on the hydrodynamics of this packing by using computational fluid dynamics. In the present work, a 3D ...

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...

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. ...

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...

While structured packing modules are known to be efficient for surface wetting and gas-liquid exchange in abiotic surface catalysis, this model study explores structured packing as a growth surface for catalytic biofilms. Microbial biofilms have been proposed as selfimmobilized and self-regenerating catalysts for the production of chemicals. A concern is that the complex and dynamic nature of b...

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...
