Determination of partial mass-transfer coefficients from concentration profiles in a distillation column.
Original language description
Method for the determination of kLa and kGa has been used on the ethanol-water system. The method consists in a fitting of the concentration profile along the column obtained by the integration of a differential model to the experimental one. The concentration profile obtained by the integration of the differential model of the column is fitted to the experimental one optimising kLa and kGa parameters. Experiments were performed in an atmospheric distillation column of inner diameter 0.15m filled with 2m of Pall ring 25mm metal packing. Seven sampling points allowing withdrawal of liquid samples were placed along the column height. The reboiler duties varying from 15 to 45 kW have been used in the experiments. The comparison of resulting kLa and kGa coefficients with those obtained by a recalculation according to commonly used absorption correlations is shown.
