Abstract
Abstract The method of gas—liquid absorption with chemical reaction was applied to determine the interfacial area and the gas-side mass transfer coefficient and implemented in a pilot column of diameter 0.45 m. This absorber was equipped successively with different trays of industrial type (bubble-cap, sieve and valve trays), so that a reliable comparison of their respective efficiencies could be made. The influence of weir height was studied especially, and also the effects of gas velocity and liquid load. The experimental results were correlated by means of empirical relations which account for the respective influences of the three parameters and provide a useful basis for extrapolation to industrial absorber design.
