A packed absorption column removes an impurity from a gas stream by contact with a liquid solvent. The column is $3 \mathrm{ft}$ in diameter and contains $25 \mathrm{ft}$ of No. 2 plastic Super Intalox packing. The gas has a MW of 28 and enters the column at $120^{\circ} \mathrm{F}$ and leaves at $10 \mathrm{psig}$ at a rate of $5000 \mathrm{scfm}$. The liquid has a SG of 1.15 and a viscosity of $0.8 \mathrm{cP}$. Determine(a) The flow rate of the liquid in gpm that would be $50 %$ of the flow rate at which the column would flood

(b) The pressure drop through the column in psi

(c) The horsepower of the blower required to move the gas through the column, if it is $60 %$ efficient
