$5\mathrm{.}4-4.$ A process for producing acetone from isopropanol is discussed in Exercise $1\mathrm{.}3-4.$ The desired production rate is $51\mathrm{.}3mo\frac{l}{h}r.$ The feed azeotrope contains $70$mol$\%$ IPA, and the costs are acetone $=$$$\frac{15\mathrm{.}66}{m}ol,$ IPA$-H_{2}O$ azeotrope $=$$$\frac{9\mathrm{.}53}{m}o{l}_{,}{H}_2$ as fuel $=$$$\frac{0\mathrm{.}49}{m}ol,$ and $H_{2}O$ as waste $=-$$$\frac{0\mathrm{.}007}{m}ol.$ Draw the input$-$output flowsheet, calculate the overall material balances, and plot the economic potential.
