In an experimental agitated contactor pure
carbon dioxide is being absorbed in water at
and atm presure. Water is pumped into the
contactor at a rate of liter per minute.
Water is pumped into the
contactor at a rate of
litre per minute and
the carbonated water
leaves the vessel
continuously so that
a constant volume
is maintained in the
contactor. The ontlet
water contains
per liter. The specific area of gasliquid contact
is of the gasliquid dispersion;
the volume of gasliquid dispersion is litres. The liquid
phase can be assumed to be well mixed. The solubility
of in water can be calculated using Henry'saw
At the Henry's law constant for is
and its diffusivity in water is
Calculate
a thickness of the liquid film if the film theory is applicable.
b the contact time betweren a liquid element with the
gas if the penetration theory is applicable.
c the fractional renewal rate if surface renewal
theory is applicable.
