I'm about to attempt this question but beforehand I was hoping if someone could just check if my diagram is correct on the basis of the question;
A feed stream contains H2, CO and a trace of CH4. Pure CH3OH is produced by means of a reactor (CO + 2H2→CH3OH), separator and recycle with purge to remove the non-reactive CH4. Feed stream composition is 67.3 mol% H2, 32.5 mol% CO and 0.2 mol% CH4. Recycle CH4 concentration is held at 3.2 mol% CH4. What is the ratio of the feed stream to purge stream flowrates?

Would I be right in thinking that I'd also need to take a basis in order to calculate any flow rates as none have been provided.
Also does the stream coming off the separator have the same composition as the recycled one ?
In my diagram I was not sure if the arrow coming off the separator also had to have its own flow rate and compositions if it were the same as the recycled stream.
Thanks in advance for any help :)
