Question

a)Determinethe total exit liquid flow, the total exit gas flow, and the solute concentration in exit gas.

b)Calculatethe number of theoretical stages needed in this absorption tower using the Kremser equation if the equilibrium relation of solute in gas-liquid is yP= 4.69xP.

A counter-current absorption tower with multiple stages is constructed to recover solute P from
an inert gas stream. The tower is designed to operate at 2 bar and 300 K. The total inlet gas
flow rate is 100 kmol/h with a solute concentration of 0.59 mol%. Meanwhile, the total inlet
liquid flow used in this process is 470 kmol/h with a solute concentration of 0.02 mol%.
Suppose the exit liquid has a solute concentration of 0.11 mol%.
