“…By computing a simplified sequential algorithm, it was found that the mass-transfer efficiency can be improved by reducing the droplet diameter in the c-to-d mass-transfer direction. This model was also used by Saremi et al 45 to calculate the mass-transfer coefficient using a best-fit technique and particle swarm optimization algorithm.…”

“…By computing a simplified sequential algorithm, it was found that the mass‐transfer efficiency can be improved by reducing the droplet diameter in the c‐to‐d mass‐transfer direction. This model was also used by Saremi et al 45 to calculate the mass‐transfer coefficient using a best‐fit technique and particle swarm optimization algorithm. Using flooding behavior experiments, Khooshechin et al 42 showed that the maximum throughput decreased with an increase in the pulse intensity and dispersed phase flow rate.…”

The method developed in our previous work (Wang et al., AIChE J. 2020; 66(8): e16257), was used to study the influence of the mass‐transfer direction and flux on the dynamic interfacial tension (DIFT) in a pulsed column. The breakup frequency was the highest near the entrance of the dispersed droplet, corresponding to the lowest interfacial tension and highest mass transfer flux. The decrease in the interfacial tension was proportional to the square root of mass‐transfer flux, and this difference is defined as a new parameter, named interfacial relaxation. When the mass‐transfer direction was changed from the dispersed phase to continuous phase to the opposite direction, the proportion of binary breakage was decreased from ~80% to ~40% and the interfacial relaxation was more sensitive to the mass‐transfer flux. A DIFT model was finally established based on the interfacial relaxation parameter, which predicted the experimental results with an error of ±10%.
