Influence of packing type on mass transfer coefficient

“Packing is helpful in making more time for gas–liquid contact throughout the CO₂ absorption process, so it can increase the surface area and K_GCO2a_V in the packed column. Recently, researchers showed that using a structured packing in the absorption column could create higher surface are as compared with random packing.⁹³ This is because of greatly higher geometric wet surface areas per structured packing volume unit. However, the packing surface area should not be the only selection criteria for creating a higher K_GCO2a_V in the packed column.⁹⁴ The other parameters affecting packing, such as packing arrangement pattern, angle of corrugation, void fraction, and height of crimp, should be also considered when designing the absorption packed column, to minimize the pressure drop and capacity of the liquid entrainment.”
