Hydrodynamics of a Gas-liquid Column Equipped with Mellapakplus Packing
نویسنده
چکیده
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 packing allows substantial gains in throughput compared to its standard counterpart, Mellapak 250.Y. Experiments were also carried out using aqueous solutions of Carboxymethylcellulose (CMC) as the liquid phase to evaluate the effect of liquid viscosity. A mechanistic model, based on massand momentum-conservation equations, is presented for the prediction of the pressure drop up to flooding point.
