Ethylene glycol is produced by air oxidation of ethylene to ethylene oxide and subsequent absorption of the oxide in water. A portion of ethylene is oxidized to CO2. 100 kgmol of a gas mixture containing 10% ethylene and 90% air is fed to the oxidizer. The gases leaving the reactor are absorbed in water fed at the rate of 10 moles per 100 moles of the original gas mixture. The off-gas leaving the absorber gave the following analysis on a dry basis: C2H4= 2.31%, CO2= 6.94% and the rest oxygen and N2. The gases leave the absorber at 101.325 kPa saturated with water vapor at 306 K. (The vapor pressure of water at 306 K is 5 kPa). Determine 1. Moles of ethylene glycol produced 2. percent conversion of ethylene to glycol moles of dry gases leaving the absorber 3. weight percent of ethylene glycol in the glycol water solution 4. extension of the reaction 1 (kgmol) 5. extension of reaction 2 (kgmol) 6. extension of reaction 3 (kgmol)
