“Several mass-transfer coefficient correlations are available for absorber columns packed with random and structured packing.12,95–98 These developed correlations differ in their accuracy and system-specific applicability. By having these correlations and calculating the enhancement factor, KGCO2aV can be obtained. However, these correlations can increase the error in calculations, for example in rate-based models, and one needs to perform a sensitive analysis for the mentioned correlations, which may not be applicable to CO2–amine systems.
The review on these correlations was done by Wang, et al.16 for random and structured packing columns. Herein, we have reviewed the empirical correlations of KGCO2aV in absorber packed columns, which were obtained experimentally, mainly from analyzing the effects of operating parameters on KGCO2aV in CO2–amine systems. The reviewed correlations in this study are presented in Table 3 and the corresponding values of operating parameters for developed correlations have been listed in Table 2.”
