The following two reactions occur in an ethylene oxide production process: 2C2H4+O22C2H4OC2H4+3O22CO2+2H2O A stream containing equimolar amounts of ethylene (C2H4) and oxygen (O2) is joined by a recycle stream containing pure ethylene and the combined stream is fed to the reactor. The single-pass conversion of ethylene in the reactor and the single pass ethylene oxide (C2H4O) yield based on ethylene consumption are defined as Xsp ( molC2H4 react/mol C2H4 fed) and Ysp (mol C2H4O formed/mol C2H4 react). The reactor effluent goes through a multiple-unit separation process that has three outlet streams. The first stream is pure ethylene oxide. The second stream contains the remaining oxygen, ethylene and the products formed according to the 2 nd reaction (take 100% yield). The third stream, which is the recycle stream, contains the remaining unreacted ethylene. Take 100mol/s fresh feed as a basis of calculation. For reaction 1, create an Excel spreadsheet to simulate this process by considering XSP=0.20 to YSP=0.90 and the separation process as a single unit. Use the recycle stream flow rate as a tear stream variable (that is, assume a recycle flow rate entering the recyclefresh feed mixing point) solve the system balance equations to recalculate the recycle flow rate at the outlet of the separation process and find the assumed value for which the assumed and recalculated values are the same
