Gas flow rate is $3538$ mole$/$min and the minimum liquid flow rate is $2448$ kg$/$min to remove SO$2$ gas. The operating liquid rate is $50\%$ more than the minimum. The packing material selected is $2"$ ceramic Intalox Saddles. Find the tower diameter and pressure drop based on $75\%$ of flooding velocity for the gas velocity. Properties of air:: molecular weight: $29$ g$/$mole; density: $1\mathrm{.}17\backslash$times $10-3$ g$/$cm$^3.$ Properties of water:: density: $1$ g$/$cm$^3.$ viscosity: $0\mathrm{.}8$ cp$.$
