An isolation flux chamber can be used to directly measure hydrocarbon emissions as it rests

on the surface of a wastewater treatment body$$s surface. Determine the emissions of

benzene, toluene, ethylbenzene and xylene in kg$/$h from an oil$-$water separator. The area of

the separator is $84$m$2$

$.$ Data from the flux chamber measurements are given in table $1.$

Assume the gases behave ideally. Q$,$ the sweep airflow rate of the flux chamber, is $5$ l$/$min

and A$,$ the area the flux chamber shares with the surface of the separator, is $0\mathrm{.}13$m$2$

$.$ The

ambient temperature is $25$C$.$ Atomic weight carbon $=12$g mol$-1$

$,$ gas constant $=0\mathrm{.}08205$ l

atm K$-1$ mol$-1$
