Absorption #1: Acetone-Water We are going to absorb 80% of the acetone in a gas stream containing 2.5 mole % acetone in air. The total inlet gas flow to the absorption column is 85.0 kgmole/hr and the total water flow is 300 kgmole/hr. The operates isothermally at 300K and a pressure of 1 atm. The equilibrium for this system is effectively characterized by either a Henry's Law relationship or Raoult's Law (using partial pressure), and a general equilibrium relationship that might be used is ya=3.00*xA. process (a) Plot the operating line and determine the minimum number of stages (graphically) for the equilibrium relationship provided. (b) Confirm the results of part (a) using the analytical Kremser equation.

Absorption #1: Acetone-Water We are going to absorb 80% of the acetone in a gas stream containing 2.5 mole % acetone in air. The total inlet gas flow to the absorption column is 85.0 kgmole/hr and the total water flow is 300 kgmole/hr. The process operates isothermally at 300K and a pressure of 1 atm. The equilibrium for this system is effectively characterized by either a Henry's Law relationship or Raoult's Law (using partial pressure), and a general equilibrium relationship that might be used is ya=3.00*XA. (a) Plot the operating line and determine the minimum number of stages (graphically) for the equilibrium relationship provided. (b) Confirm the results of part (a) using the analytical Kremser equation. (c) Determine (validate) the equilibrium relationship that was assumed by determining and referencing a Henry's Law constant and also Raoult's Law. [References / Sources needed] (d) Repeat parts (a) and (b) for the equilibrium relationships determined in part (c). How significant are the equilibrium assumptions on the overall estimates for the number of stages needed?
