Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor according to the following reaction: CO + 2H2 --> CH3OH The fresh feed to the process contains CO, H2, and N2. This stream is mixed with a recycle stream to produce the feed to the reactor. A low single-pass conversion is attained in the reactor. The reactor effluent flows at a rate of 550 kmol/h and contains 27.0 mole% CO, 54.0% H2, 14.0% N2, and 5.0% CH3OH. It goes to a condenser from which two streams emerge: a liquid product stream containing essentially 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, and the other is the recycle stream that combines with the fresh feed to the reactor. The overall conversion of CO is 76%. Calculate the following: 1. Production rate of methanol (kmol/h) 2. Molar flow rate (kmol/h) and composition of the gas stream leaving the condenser 3. Molar flow rate (kmol/h) and composition of the purge stream 4. Molar flow rate (kmol/h) and composition of the fresh feed 5. Molar flow rate of CO (kmol/h) in the recycle stream
Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor according to the following reaction:
CO + 2H2 --> CH3OH
The fresh feed to the process contains CO, H2, and N2. This stream is mixed with a recycle stream to produce the feed to
the reactor. A low single-pass conversion is attained in the reactor. The reactor effluent flows at a rate of 550 kmol/h and
contains 27.0 mole% CO, 54.0% H2, 14.0% N2, and 5.0% CH3OH. It goes to a condenser from which two streams emerge: a
liquid product stream containing essentially 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, and the other is the recycle stream that combines with the fresh feed to the reactor. The overall conversion of CO is
76%. Calculate the following:
1. Production rate of methanol (kmol/h)
2. Molar flow rate (kmol/h) and composition of the gas stream leaving the condenser
3. Molar flow rate (kmol/h) and composition of the purge stream
4. Molar flow rate (kmol/h) and composition of the fresh feed
5. Molar flow rate of CO (kmol/h) in the recycle stream
6. Single-pass conversion of CO
