Example 4.7-3 Recycle and Purge in the Synthesis of Methanol Methanol is produced in the reaction of carbon dioxide and hydrogen: CO2+3H2CH3OH+H2O The fresh feed to the process contains hydrogen, carbon dioxide, and 0.400 mole % inerts (I). The reactor effluent passes to a condenser that removes essentially all of the methanol and water formed and none of the reactants or inerts. The latter substances are recycled to the reactor. To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. The feed to the reactor (not the fresh feed to the process) contains 28.0 mole CO2, 70.0 mole %H2, and 2.00 mole\% inerts. The single-pass conversion of hydrogen is 60.0%. Calculate the molar flow rates and molar compositions of the fresh feed, the total feed to the reactor, the recycle stream, and the purge stream for a methanol production rate of 155kmolCH3OH/h
