A gas stream containing acetone (58 g/mol) in air flows from a solvent recovery unit at a rate of 142 Liters/s at 150°C and 1.3 atm. The stream flows into a condenser which liquefies most of the acetone, and the liquid and gas outlet streams are in equilibrium at 0°C and 5 atm. Shaft work is delivered to the system at a rate of 25.2 kW to achieve the compression from 1.3 atm to 5.0 atm. To determine the condenser feed stream composition, a 3.00- liter sample of the gas is taken and cooled to a temperature at which essentially all the acetone in the sample is recovered as a liquid. The liquid is weighted to be 0.956 g. Assume ideal gas. Determine 1), the mole fractions of acetone in the feed and product gas streams, and 2), the rate (kW) at which heat must be removed in the condenser. Antoine Equation for acetone, P [mm Hg], T [°C] +2. 1210.595 log10 Psat = 7.11714 T + 229.664
