Question 1 Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor. The fresh feed to the process contains 32% (n/n) CO; 64% (n/n) H2; and 4% (n/n) N2. This stream is mixed with a recycle stream in a ratio 5 mol recycle/1 mol fresh feed to the reactor, which contains 13% (n/n) N2. A low single-pass conversion is attained in the reactor. The reactor effluent goes to a condenser, from which two streams emerge: a liquid product stream containing all the methanol formed in the reactor, and a gas stream containing all the Co, H2, and N2 leaving the reactor. The gas stream is split into two fractions: one is removed from the process as a purge stream, while the other is the recycle stream that combines with the fresh feed to the reactor. a. Draw the system, inserting all relevant information. b. For a basis of 100 mol fresh feed/hr, calculate the production rate of methanol, the molar flow rate and composition of the purge stream, and the overall and single-pass conversions of the reactor.
