Formaldehyde is produced industrially by the catalytic oxidation of methanol following this reaction: CH3OH → HCHO + H₂ A certain manufacturing plant aims for a production rate of 900 kg/h of formaldehyde. To achieve this, a single pass conversion was maintained at 60%. The product from the catalytic reactor is separated into two streams. The first stream is a mixture of formaldehyde and hydrogen which is removed from the process. The second stream is pure methanol that is recycled to the reactor. Determine the rate of recycled methanol and the rate of the fresh methanol needed (kmol/h).

Transcribed Image Text:Formaldehyde is produced industrially by the catalytic oxidation of methanol
following this reaction:
CH3OH → HCHO + H₂
A certain manufacturing plant aims for a production rate of 900 kg/h of
formaldehyde. To achieve this, a single pass conversion was maintained at 60%.
The product from the catalytic reactor is separated into two streams. The first
stream is a mixture of formaldehyde and hydrogen which is removed from the
process. The second stream is pure methanol that is recycled to the reactor.
Determine the rate of recycled methanol and the rate of the fresh methanol
needed (kmol/h).
