Air at a flow rate 1.70 m2/h (16 oC, 1

 

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?
