AIChE Journal Highlight: Absorption Methods Determine Mass-Transfer Parameters of Packed Beds

August
2017
Journal Highlight
To design and analyze absorber columns, engineers need reliable mass-transfer parameters for rate-based models in process simulations. However, unlike for distillation, no set of standardized measurement methods for absorption have been generally accepted. Mass-transfer parameters measured by different methods at different facilities, or calculated from different correlations, can have significant disparities. Thus, a need exists to improve the precision and accuracy of experimental methods for determining mass-transfer coefficients so that reliable and coherent sets of data can be derived.
