P4.14 Dimethyl carbonate (DMC, C3H6O3) can be synthesized by a process called oxidative carbonylation of methanol: 2CH3OH + CO + 1/102 CHO3 + HO A gas containing 80 mol% CH3OH and 20 mol% CO at 2000 gmol/h is mixed with air (79 mol% N2 and 21 mol% O2) and then fed to a reactor operating at steady state, where the reaction takes place. The flow rate of the stream leaving the reactor is 2264 gmol/h, and this stream contains no O2. Draw a flow diagram and write the correct form of the material balance equations for all compounds in this system. Determine the flow rate of air to the reactor, the extent of reaction &, and the composition (mol%) of the reactor effluent.
