Structured Packing Flooding: Its Measurement and Prediction
نویسندگان
چکیده
A cryogenic pilot distillation column operating at total reflux is described. It was used to measure the pressure drop and flooding of various structured packings, first using pure nitrogen and then using an oxygen-argon mixture. By varying the pressure, the nitrogen system was used to characterize the capacity of each packing via Wallis plots. The oxygen-argon flooding data can be accurately predicted only if it is assumed that the pressure drop at flooding is proportional to the liquid density, in agreement with an earlier suggestion by McNulty.

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...
متن کاملModifications to Structured Packings to Increase Their Capacity
The hydraulic performance of structured packed columns is characterised by parameters such as loading point, flooding point, dry and wet pressure-drop. These parameters can be positively influenced by optimising the transition areas between two adjacent packing layers. Tests have been done in a two-phase test rig with a rectangular column made of perspex. The test medium is a liquid hydrocarbon...
متن کاملCFD Simulation of Dry and Wet Pressure Drops and Flow Pattern in Catalytic Structured Packings
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 ...

This paper describes the results of an experimental and modelling study on hydrodynamics of MellapakPlus packing operated under counter-current gas-liquid flow. The experimental work was focused on measuring the pressure drop, liquid holdup and capacity limit of this packing at specific liquid loads of up to 80 m/m/h. Experimental results for the air/water system confirm that MellapakPlus packi...
متن کاملCFD 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...
