A stream of hot thy nitrogen flows through a process unit that contains liquid acetone. A substantial portion of the acetone vaporizes and is carried off by the nitrogen. The combined gases leave the recovery unit at 205°C and 1.1 bar and enter a condenser in which a portion of the acetone is liquefied. The remaining gas leaves the condenser at 10°C and 40 bar. The partial pressure of acetone in the feed to the condenser is 0.100 bar, and that in the effluent gas from the condenser is 0.379 bar. Assume ideal-gas behavior. (a) Calculate for a basis of 1 m3 of gas fed to the condenser the mass of acetone condensed (kg) and the volume of gas leaving the condenser (m3). (b) Suppose the volumetric flow rate of the gas leaving the condenser is 20.0 m3/h. Calculate the rate? (kg/h) at which acetone is vaporized in the solvent recovery unit.
