thylene oxide

thylene oxide is produced by the oxidation of ethylene over a catalyst. Safety consideration dictates that the gaseous mixture entering the reactor should contain 10 mol air per mol ethylene. The conversion per pass is 22%. The ethylene oxide formed is completely condensed out and the remaining gases recycled. Make up oxygen is added to maintain the requisite oxygen levels. For a plant producing 440 kg/h of ethylene oxide, 1) Calculate the quantity of pure make up oxygen to be supplied, (in kg/h), in steady state operation. The relevant reaction is represented by 2C2H4 + O2 ? 2C2H4O Process Calculations: Material Balance
