the partial pressure of acetone in a contaminated air stream at $1$ atm$6-14.$ The partial pressure of acetone in a contaminated air stream at $1$atm and $100C$ is

$100mmHg.$ An adsorption bed of activated carbon is used to remove the acetone. The

bed is $3\mathrm{.}5m$ thick and has a flow area of $7m^2.$ The gas flow rate is $1\mathrm{.}5k\frac{g}{s}.$ Determine

the time of breakthrough for this bed based on the following data: $=17\mathrm{.}3k\frac{g}{m^3},$

$=2\mathrm{.}23,K=40s^{-1}.$ The apparent density of the adsorbent is $380k\frac{g}{m^3}.$
