A liquid make sure of acetone and water contains 35 mole% acetone. The make sure 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.
A) Pose the process is to be carried out continuously and I had a steady-state with a feed rate of 10.0kmol/h. Let n sub v and n sub l be the flow rates of the vapor in liquid product streams respectively. Draw And label a process flowchart then write and solve balances on total moles and on acetone to determine the values of n sub v and n sub l. Each balance state which terms in the general balance equation (accumulation = input + generation - output - consumption) can be discarded and why.
B) now suppose the process is to be carried out in a closed container that initially contains 10.0 kmol of the liquid mixture. Let n sub v and n sub l be the moles of final vapor and liquid phases respectively. Draw And label a process flowchart then write and solve integral balances on total moles and on acetone. For each balance, state which terms of the general balance equation can be discarded and why.
C) returning to the continuous process, supposed evaporation unit is billed and started in the product stream flowrates and compositions are measured. The measured acetone content of the vapor stream is 75 mole% acetone and the product stream flow rates have the values calculated in part a. However the liquid product stream is found to contain 22.3 mole% acetone. It is possible that there is an error in the measured composition of the liquid stream, but give at least five other reasons for the discrepancy. (Think about assumptions made in obtaining the solution of Part a)
