Absorption in packed towers with concurrent downward high‐velocity flows—II: Mass transfer

Abstract

Abstract Measurements were made of mass transfer coefficients with gas and liquid phase controlling resistance using a concurrent flow packed column with a wide range of operating conditions and four types of packing. Mass transfer coefficients were much larger than those obtainable in countercurrent towers. The results were correlated with dissipated energy values. The correlations obtained can be used to determine absorption efficiency. Experimental results show that the use of a high velocity concurrent flow column is particularly suitable when mass transfer is controlled by the liquid phase resistance with chemical reaction in the liquid.
