The relation between local radial pressure gradient, with packaging material and liquid dr properties is represented in Eq (1) dp Фр аз dr pvz 1-a 150u(1-a) 1.75y + ρνοΦΡ Eq(1) Where : Pp: packing material properties diameter (m) a: fraction void (dimensionless) y: correction factor (dimensionless)=0.2 p: liquid solvent density (kgm?) u: amine liquid viscocity (Pa.s) Characteristics of the proprietary packing considered in this project and the simplified stream pilot plant data can be obtained in Table 1 and Table 2 respectively.
