| Abstract: | An approach for the simulation of separation processes in packed columns is based on hydrodynamic analogy between complex flow pattern in real equipment units and geometrically simplified model flow and is known as the Hydrodynamic Analogy (HA) approach. In this work, the HA approach was applied to reactive absorption of CO2 in aqueous sodium hydroxide solution under turbulent gas flow conditions. An extensive experimental study was carried out to measure the CO2 concentration profiles along the column height. These data provided a basis for a successful validation of the HA approach. |
