Modelling of gas/vapour-liquid separation processes usually requires experimentally determined parameters, e.g. mass transfer coefficients that cannot be determined without expensive experimental work. A novel modelling approach based on hydrodynamic analogies (HA) has recently been developed and successfully tested for distillation units equipped with structured corrugated sheet packings. The HA approach is an alternative way to describe hydrodynamics and transport phenomena in processes, in which exact location of the phase boundaries is hardly possible. Contrary to the traditional models based on the film theory, separation columns can be described without using mass transfer coefficient correlations. In this work, the HA approach was applied to carbon dioxide absorption into aqueous monoethanolamine. The composition profiles were determined in an absorption column filled with structured packings. For the model validation, experimental data from literature were used.
