Analogy of mass transfer in absorption and distillation columns: Wetted wall column study distillation

Popis výsledku v původním jazyce

Rate-base modeling of packed distillation columns represents an advanced approach to design these devices. Compared to the traditional stage-wise approach the rate-based modeling offers more information about the conditions inside the column and enables to the column designer to simulate the behavior of the column if the operation conditions are changed. The possibilities of the rate-based approach are limited by the reliability of mass-transfer parameters, the mass-transfer coefficients. Unlike the absorption conditions, the measurement of the individual mass-transfer coefficients under distillation conditions in the industrial scale columns has never been mastered. Therefore, the values of those parameters for distillation conditions are usually recalculated out of the results of standardized absorption experiments. The possibility of such recalculation, i.e. the analogy of the mass-transfer in absorption and distillation columns, is tacitly assumed. This work is focused on the study of this analogy and the possibility of the recalculation of the mass-transfer coefficients between absorption and distillation conditions in the wetted wall column.
