. When analyzing effects of operating parameters and the size of the stripper on the CO2 regeneration process, in order to increase the separation performance and reduce the regeneration energy, the stripper was packed with DZ-II-750Y, one of the CY structured packings, which is more favorable for separation than the Pall rings [67] and [68]. The relevant parameters of the DZ-II-750Y structured packing are shown in Table 1[66].
