Problem $4.$ Absorption of acetone from air: An air stream contaminated by $2$mol$\%$ acetone is fed into a one$-$stage absorber at a rate of $40$kmo$\frac{l}{h}.$ The absorber operates isothermally at $25C$ and utilizes pure water flowing at a rate of $30$kmo$\frac{l}{h}.$ Using the graphical method and the vapor$-$liquid equilibrium data for acetone$-$water system, estimate the product stream compositions.
