Q2 (30 marks) Solid soaked with liquid hexane are dried by being contacted with nitrogen at an elevated temperature. The gas stream leaving the dryer is at 80 C, 1 atm absolute, and 50% relative saturation. One of several possibilities for recovering the hexane from the gas is send to the stream to a cooling condenser. The gas stream leaving the condenser would contain 5.00 mole% hexane, and hexane condensate would be recovered at a rate of 1.50 kmol/min. The condenser would be operated at a pressure of 1 atm absolute. Calculate the temperature to which the gas must be cooled and the required flow rate of fresh nitrogen to the dryer in standard cubic meters per minute (SCMM).
