Notes:
A study was made of separating the volumetric mass transfer coefficients, kGa and kLa, into their components kG, kL, and a so that the effects of variables might be determined separately for each component. Mass transfer rates for four packings, 1/2- and 1 1/2-in. Raschig rings and 1/2-in. and 1-in. Berl saddles, made of naphthalene, were determined by vaporization into air at gas rates from 100 to 1,000 1b./(hr.) (sq. ft.).The correlation for kGa was used to determine the wetted areas of those packings when irrigated with water and to calculate the effective interfacial areas, a, from Fellinger's data for ammonia absorption. These effective areas were then used to evaluate kL from previously published kLa data, and a correlation was obtained for all packings.The correlations for kGa and kLand the effective-interfacial-area data make possible a more rigorous method for the design of packed columns than was heretofore available.
