A model is presented for the steady‐state simulation of a CO 2 recovery pilot plant with aqueous monoethanolamine (MEA) solutions. CO 2 absorption is performed in a column packed with 2.54 cm ceramic Pall rings. CO 2 recovery is achieved in a 20 sieve tray steam stripping column. The packed column absorption model was fitted to the experimental data using the specific interfacial area of the irrigated packing as an adjustable parameter. The equivalent average bubble diameter was used as the adjusting parameter in the sieve tray stripping column. Modelling of both towers reproduces within 3% average error concentrations measured in a pilot plant. Measured temperatures were also well correlated.
