Stripping of CO2 from water by air in a wetted-wall tube.Carbon dioxide is stripped from water by air in a wetted-wall tube. At a location where pressure is 10 atm and temperature 25oC,the flux of CO2 is 1.62 lbmol/h-ft2. The partial pressure of CO2 is 8.2 atm at the interface and 0.1 atm in the bulk gas. The diffusivity of CO2 in air at these conditions is 1.6 x10-2 cm2/s. Assuming turbulent flow, calculate by film theory the mass-transfer coefficient kc for the gas phase and the film thickness.

Distillation

Distillation is a process/technique to separate more volatile components from less volatile components using the principle of relative volatility. In chemical engineering, distillation is one of the most common and important topics that is involved in almost every industry and process.
