Design of membrane based gas-liquid absorption units: a fast, efficient, high throughput batch to continuous methodology

Résumé

Membrane contactors offer promising perspectives for intensified gas-liquid absorption processes. A rational design of a membrane-based absorption process ideally requires evaluation of membrane material / solvent compatibility, and key thermodynamics and kinetics data. More specifically, impact of gas and liquid velocities, and solvent loading, on effective mass transfer performances are of major importance for design purposes. Classical, time consuming membrane gas absorption tests with different inlet solvent loadings are most often separately performed to determine these different data sets. A fast, compact, easy to use method has been developed to assess, through one experiment, both thermodynamics and mass transfer data based on a batch to continuous approach. The set-up can easily be used for studies of membrane and solvent performance. These aspects will be shown and discussed, based on experiments performed with chemical solvents for CO2 absorption from a gaseous mixture.
