1. Gas absorption with a first order reaction: CO2 is absorbed into a liquid under conditions such that the liquid side mass transfer coefficient is 2 × 10-4 m/s. The diffusion coefficient of CO2 in the liquid is 2 × 10-9m²/s. The interfacial concentration of CO2 can be found using the Henry's law. Henry coefficient for CO2 is 0.0315 bar m³/mol when expressed as p = HC at equilibrium, the C being the concentration in the liquid. The pressure is 1atm and temperature is 300K. Assume that CO2 reacts with a dissolved solute in the liquid with a rate constant of 1s¹. Also assume that the bulk concentration of CO2 is zero. a. Find the Hatta number. b. Find the flux of CO2 at the interface c. Find the flux of CO2 going into the bulk liquid. d. What percentage of CO₂ reacts in the film itself?

Question
Transcribed Image Text:1. Gas absorption with a first order reaction: CO₂ is absorbed into a liquid under
conditions such that the liquid side mass transfer coefficient is 2 x 10-4m/s. The
diffusion coefficient of CO₂ in the liquid is 2 x 10-⁹m²/s. The interfacial
concentration of CO₂ can be found using the Henry's law. Henry coefficient for
CO₂ is 0.0315 bar m³/mol when expressed as p = HC at equilibrium, the C being
the concentration in the liquid. The pressure is 1atm and temperature is 300K.
Assume that CO₂ reacts with a dissolved solute in the liquid with a rate constant
of 1s-¹. Also assume that the bulk concentration of CO₂ is zero.
a. Find the Hatta number.
b. Find the flux of CO₂ at the interface
c. Find the flux of CO₂ going into the bulk liquid.
d. What percentage of CO₂ reacts in the film itself?
