1. Methanol is produced in the reaction of carbon monoxide and hydrogen: CO + 2H2 CH3OH Following Figure illustrates a steady-state process for the production of methanol. All of the compositions are in mole fractions or percent. The stream flows are in moles. The fresh feed to the process contains 67.3 mole % hydrogen, 32.5 mole% carbon monoxide, and 0.2 mole% methane (CH). Methane enters the process, but does not participate in the reaction. A purge stream is used to maintain the CH4 concentration in the air from the separator at no more than 3.2 mol%, and prevent hydrogen buildup as well. The once-through conversion of the CO in the reactor is 18%. Compute the moles of feed to reactor (A), feed to separator (B), recycle (R), methanol (C), and purge (P) per 100 moles of fresh feed, and also compute the recycle and purge gas compositions.
