Ethylene oxide (C2H4O) is produced by the catalytic oxidation of ethylene (C2H4) in the reaction 2C2H4+O2⟶2C2H4O. Unfortunately ethylene can also completely combust as a second, undesired side reaction. These two reactions are occurring in a multi-unit reactor/separator system. The single pass conversion of ethylene in the reactor is 25% and for every 100. mols of ethylene consumed in the reactor, 90.0 moles of ethylene oxide are produced. A separation system is used to separate the components in the reactor effluent. Ethylene and oxygen are recycled, ethylene oxide is sold, and carbon dioxide and H2O are purged. The recycled ethylene and oxygen combine with the fresh feed to make a feed to the reactor containing 3.00 mols of ethylene per 1.00 mol of oxygen. a) Draw and fully label the process flow diagram including variables for component molar flow rates in each stream rather than total flow rates and mole fractions. b) For a basis of 100. mol/h of ethylene consumed in the reactor, fill in the PFD with values of all non-zero component molar flow rates in mol/h.
