A trayed column is used to recover acrylic acid and acetic acid from a dilute gas stream by absorption in water. At the same vapor concentration, acrylic acid is about two times as soluble as acetic acid in water. If a column is to be designed for 99.9% recovery of acrylic acid from a vapor stream initially containing 0.5mol% acrylic acid and 0.5mol% acetic acid, how many equilibrium stages are needed? What will be the outlet mole fraction of acetic acid from the absorber/. The absorption factor for acrylic acid is A=L/KV=1.5
