A gas mixture containing 85.0 mole% N_2, and the balance n-hexane flows through a pipe at a rate of 100.0 m^3/h. The pressure is 2.00 atm absolute and the temperature is 100 degree C. What is the molar How rate of the gas in kmol/h? Is the gas saturated? If not, to what temperature would it have to be cooled at content pressure in order to begin condensing hexane?

CONFIDENTIAL BKC/1617/BKF2343 QUESTION 1 An equimolar vapor mixture of n-pentane and n-hexane at 110°C and 1 atm is fed into a condenser at a rate of 200 L min When the feed is cooled and compressed in the condenser, some of the vapor is condensed. The products are separated and discharged in separate streams. The vapor and liquid products at the top and the bottom of the condenser are(in equilibrium at 60°C and pressure P mmHg. The vapor product stream...

Question: 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. (a) 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 5.00 moles% of hexane, and hexane condensate would be recovered at a rate of 1.50 kmol/min. The condenser...
