A process is designed to produce formaldehyde by the partial oxidation of methanol with air according to the following reaction:

$C{H}_{3}OH+\frac{1}{2}{O}_2$HCHO$+H_{2}O$

The gas mixture fed to the reactor $($stream $4$ in the flow diagram below$)$ contains $8$ mole $\%$ methanol and $10$ mole $\%$ oxygen. The single$-$pass conversion of methanol is $100\%.$ The gas stream leaving the top of the separator contains only oxygen and nitrogen.

Calculate the molar flow rates of streams $1,2,3,4,$ and $5$ needed to produce $3000k\frac{g}{m}in$ of formaldehyde$/$water solution having a composition of $37$ mass $\%$ formaldehyde.A process is designed to produce formaldehyde by partial oxidation of methanol with air according to the following reaction: $"$CH$3$OH $+1/2$ O$2->$ HCHO $+$ H$20."$ The gas mixture fed to the reactor $($stream $4$ in the flow diagram below$)$ contain $8$ mole$\%$ methanol and $10$ mole$\%$ oxygen.
