A liquid mixture of acetone and water contains 35 mole% acetone. The mixture is to be partially evaporated to produce a vapor that is 75 mole% acetone and leave a residual liquid that is 18.7 mole% acetone. Suppose the process is to be carried out continuously and at steady state with a feed rate of 10.0 kmol/h. Let n_ v and n_l be the flow rates of the vapor and liquid product streams, respectively.
Required:
Draw and label a process flowchart, then write and solve balances on total moles and on acetone to determine the values of n_ v and n_l .
