Question

When Ethylene is oxidized, two products ethylene oxide (desired) and CO2 . are produced (by-product). Express the molar flows of the reactants at the tip of the reaction cell as level of response method, know: 2C2H4 + first 2 O2 → C2H4O C2H4 + 3O2 → 2CO2 + 2H2O Input to a reaction vessel (not initial input) containing 3 mol of ethylene/1 mol oxygen. The one-time conversion of ethylene is 20% and for every 100 moles of ethylene consumed absorbed in the reaction vessel, 90 moles of ethylene oxide appears in the product after reaction response. A multi-equipment process is used to separate the products: ethylene and oxygen is circulated back to the reactor, ethylene oxide is removed as a product and CO2 is lost removed from the process. a. Use 100 moles of reaction vessel input (not initial input) as base nature, perform a degree of freedom analysis, find: ethylene and oxygen flow in the input stream starting material, ethylene oxide product flow after cleavage, total conversion of ethylene. b. Find the molar flows of ethylene and oxygen in the initial input stream to produce 1 ton/h ethylene oxide
