Production of ethylene oxide (CH2)2O can be accomplished by oxidation of ethane C2H6 gas as shown by the reaction equation. 26 + 2 (2 )2 + 2 The mol ratio of air to C2H6 in the reactor feed is 5:1 respectively. The conversion of C2H6 on a single pass through the reactor is 85%. All the unreacted ethane is separated by azeotropic distillation and recycled to combine with the fresh feed. If 1000 kmol/hr of
