Analogy of absorption and distillation processes. Wetted-wall column study

Popis výsledku v původním jazyce

This article is the second one from a pair focusing on the mass transfer fundaments and the analogy between the processes of absorption and distillation. The wetted wall column, a device with known interfacial area, was built for this purpose enabling evaluation of the mass-transfer coefficients instead of the volumetric mass-transfer coefficients usually provided by experiments in the packed columns. The analogy of the processes has been assessed by comparison of the mass-transfer characteristics (HETP, individual mass-transfer coefficients k(L), and k(G)) evaluated on the basis of the absorption experiments with those found under the distillation conditions. In the prior paper the results of the absorption experiments performed under distillation-like conditions have been published in the form of dimensionless correlations Sh(L) = 0.33 (ReL-0.12ScL0.47) and Sh(G) = 0.012 (ReLGScG0.61)-Sc-0.90. In this paper we present results of the distillation experiments in the form of the HETP data and mass transfer coefficients evaluated by the profile method. The experimental data are compared with those predicted on the basis of the absorption experiments results. The experimental HETP data acquired on the methanol-n-propanol and ethanol-n-propanol systems agree within 10-20% with the data predicted.
