A gas stream at|1 atm pressure consists of equimolar quantities of nitrogen and a solvent vapour. Given the economic value of the solvent, a process is being designed for its recovery. This process involves cooling the gas stream, condensing a portion of the solvent, and discharging the remaining gas. Two fluids are available for use as coolant in the condenser: water at 25 C and refrigerant at -30 C. The condenser outlet temperature can be assumed to be equal to the coolant temperature. Other than this assumption, the coolant simply flows in and out of the condenser and is therefore not a factor in your calculations. The condenser is operated such that the gas discharge and condensate streams are at equilibrium. C6H6 The vapour pressure of the solvent can be taken to be the same as benzne for any temperature involved in this problem (i.e., you do not need to be concerned with the specified temperature range for any relevant vapour pressure expression). Which coolant (water or refrigerant) will enable the highest percentage recovery of the solvent (ratio of solvent condensate to solvent in the gas stream at the condenser inlet)?
