Air at a flow rate 1.70 m2/h (16 oC, 1 atm) and containing 0.5 mol % ethylene acetate
and no water vapor is to be treated with activated carbon with an equivalent particle
diameter of 3.35 mm in the fixed bed adsorber to remove the ethylene acetate, which
will be subsequently stripped from the carbon by stream at 110oC. Based on the
following data given at Table 1 and 2 , determine
a) the diameter and
b) high of the carbon bed,
assuming the adsorption at 38 o C and 1 atm and a time to breakthrough of 8 h with
superficial gas velocity of 0.3048 m/s.
If the bed high to diameter is unreasonable, what change in design basis would you
suggest?
