Carbon monoxide and hydrogen reacts to give methanol: CO+2H2→ CH3OH The conversion of CO entering the reactor is 50%. A feed stream consisting 30% CO, 60% H2, and 10%CH4 is mixed with a recycle stream and sent to a reactor. The methane leaving the reactor is separated and the unconverted gases are recycled. To prevent the accumulation of CH4 and keep its concentration, in the recycle stream at 3%, a portion of the recycle stream is blown off. For 400 moles\hr of fresh feed, determine the following: a. recycle stream (moles\hr), b. purge stream (mole\hr) c. composition of purge (mole\hr) and d. molar flowrate of methanol.

A feed stream consisting 30% CO, 60% H2, and 10%CH4 is mixed with a recycle stream and sent to a reactor. The methane leaving the reactor is separated and the unconverted gases are recycled. To prevent the accumulation of CH4 and keep its concentration, in the recycle stream at 3%, a portion of the recycle stream is blown off. For 400 moles\hr of fresh feed, determine the following: a. recycle stream (moles\hr), b. purge stream (mole\hr) c. composition of purge (mole\hr) and d. molar flowrate of methanol. Purge (P, mol) CO= x CO= x CH4= 0.03 Recy H2= 0.97-x CH4= 0.03 H2= 0.97-x Product REACTOR SEPARATOR CO, H2, CH4 CH3OH (M, mol)
