Working Session $10$

Methanol $(C{H}_{3}OH)$ is produced by reacting carbon monoxide $(CO)$ and hydrogen $(H_2).$ Only $15\%$ of carbon monoxide entering the reactor is converted to methanol. The methanol formed in the reactor is liquefied in a condenser and is recovered completely. The un$-$reacted $CO$ and $H_2$ are recycled and subsequently combined with the fresh feed containing $CO$ and $H_2$ before feeding to the reactor. For $1000mo\frac{l}{h}$ of liquid methanol produced, Calculate

a$)$ the molar flow rates of $CO$ and $H_2$ in the fresh feed.

b$)$ the moles of recycled gases per mole of feed to the reactor.

c$)$ the percentage conversion of $H_2$ in the reactor.

Draw a process flowchart and specify the method used to solve the problem.
