MODELLING OF THE SUBSTANCE TRANSFER IN THE GAS-LIQUID SYSTEM WITH CHEMICAL REACTION

In this paper substance transfer phenomena in the multistage reactive system were investigated. Substance transfer between liquid and gas phases in a distillation packed column with reaction esterification was examined. Efficiency of substance transfer were examined by HTU-Height of transfer units and volumetric substance transfer coefficients. The esterification reaction of the ethanol and acetic acid was examined. Based on derived mathematical model the total height of transfer units and individual height of transfer units for the liquid and gas phases were determined. The investigation was performed by computer simulation and experiments. Several correlation models for HTU/NTU and substance transfer coefficients were studied. The correlations for component transfer were derived in quaternary systems ethanol-ethyl acetate-acetic acid -water.
