Liquid-phase mass-transfer coefficients of Mellapak structured packings under desorption of oxygen from primary alcohols
Original language description
Volumetric mass-transfer coefficient in the liquid phase, k(L)a, for Mellapak 250.Y, 350.Y and 500.Y structured packings has been measured by standard method of desorption of oxygen into nitrogen from pure methanol, ethanol and n-propanol in the column of i.d. of 150 mm. Although utilization of organic solvents for absorption experiments provides valuable behavior interlink between properties of aqueous absorption systems and ordinary (organic) systems under distillation conditions, studies of such kind are not published in the open literature. The behavior of the k(L)a data on alcohol systems do not differ significantly from that found for aqueous system, the k(L)a values rise with the liquid load powered to similar to 0.5-0.78. For one solvent the k(L)a are almost identical for all three packings under the same liquid load. According to the expectations the k(L)a values under the same superficial liquid flow rate are highest for the solvent with the lowest viscosity and the highest diffusivity of oxygen, methanol, and decrease in the order ethanol, n-propanol and water. The k(L). data for all three packings, alcohols and also for water has been successfully correlated by dimensionless correlation Sh = 0.207. Re(0.798)Fr(-0.563)We(0.511)Sc(0.528) with mean relative deviation of 12%.
