Gas-liquid flow modeling in columns equipped with structured packing
This paper deals with the modeling of gas-liquid flow in distillation columns equipped with structured packing. The devices are seen as bi-structured porous media and a macro-scale model is proposed taking into account this specific geometry. In this model, the two liquid films, one-per-sheet, are treated separately and are allowed to exchange matter at the vicinity of the contact points betwee...
متن کاملHydrodynamics of a Gas-liquid Column Equipped with Mellapakplus Packing
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 کاملFluid Separation Modelling in the Columns Equipped with Structured Packings using the Hydrodynamic Analogy
A new modelling approach to the description of mass and heat transfer in columns equipped with structured packings is developed based on rigorous equations of continuum mechanics. This approach rests on the analogy between the flow patterns in real structured packings and film flow. The physical model is based on a simplified geometrical representation of the packing. It consists of a bundle of...
متن کاملModeling of Mixture Separation in a Column with Structured Packing. Effects of Liquid Maldistribution
INTRODUCTION. What is the effect of maldistribution on the mass transfer efficiency of a distillation column containing structured packing?. The column of structured packing is considered to consist of a set of unit cells. Each pair of sheets gives a two-dimensional set of " elementary " cells:
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...
