Chemical Engineering question. Box all answers and draw flow chart of process if necessary.
2. Problem 6.24 only from 4th Edition or 6.23. from 3rd Edition. Do part (a). Below is the problem statement. Solids 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 to send the stream to a cooling condenser. The gas stream leaving the condenser would contain 5.00mole% hexane, and hexane condensate would be recovered at a rate of 1.50kmol/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 standard cubic meters per minute (SCMM). Assume ideal gas law is applicable and use Antoine Equation to relate vapor pressure to temperature.
