FRESH FEED: $10,000$kmo$\frac{l}{h}r,$ phase: $100\%$ liquid $($bubble point$),$ standard pressure

REACTOR $1$: Reactor one takes a feed which is a mixture of three streams: fresh feed,

recycle $1,$ recycle $2$

$o-$xylene $p-$xylene $[conversion=50\%]$

$m-$xylene $p-$xylene $[conversion=66\%]$

SEP $1$: Separator one takes the output of R$1$ as a feed, and has two output streams. One

output stream is recycled to the reactor.

Split fractions of FEED to RECYCLE $1$: These split fractions are based on mole ratios of

how much is input into the separator to how much leaves in the recycle stream $-25\%$ of

p$-$xylene input, $80\%m-$xylene input, $25\%$ o$-$xylene input.

SEP $2$: Separator two takes the $($non$-$recycle$)$ output of SEP $1$ as a feed and has two

output streams. One output stream is recycled to the reactor. The other output stream is

a product stream.

Split fractions of FEED to RECYCLE $2$: $5\%$ of p$-$xylene input, $50\%$ of m$-$xylene, $5\%$ of o$-$

xylene
