On the modeling of gas-phase mass-transfer in metal sheet structured packings
Original language description
This paper refers on gas mass-transfer characteristics of several metal sheet Mellapak structured packings (M250Y, M350Y, M452Y, M500Y) under absorption conditions. These characteristics have been measured using standard absorption systems of SO2 chemisorption into the NaOH aqueous solution (kGa) and CO2 chemisorption into the NaOH aqueous solution (effective area a). Measurements were performed with four elements of the packing with diameter of 0.29 m and total height of 0.84 m. The experimental valuesof kG are in the most cases significantly under-predicted by fundamental mass-transfer models, wetted-wall column correlations and by the model packages developed for structured packing. The exponent 0.622 of gas Reynolds criteria is lower than expectedby the models starting from the imagination of the flow through the channel and corresponding experiments with wetted-wall columns. The revealed value of the exponent agrees better with those found for flow around submerged objects like
