Transcribed Image Text:3.
Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor. The fresh feed (100
moles per hour) to the process contains 32.0%CO, 64.0% H₂, and 4.0% N₂. This stream is mixed with a recycle stream
in a ratio of 5 mole recycle per 1 mole of fresh feed to produce the feed to reactor, which contains 13.0 mole % 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 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.:
a. Draw the correct block flow diagram for the described process. Label completely. State your assumptions and
basis if applicable.
b.
For the given flow rate of the fresh feed, calculate the following:
i.
Rate (mol/min) of methanol production.
iv.
V.
Rate (mol/min) of the purge gas.
Composition of the purge gas.
Overall conversion
Single pass conversion.
