Mass Transfer between Gases and High Viscosity Liquids on Rotating Cylinder with Surface Renewal Action

In many polymer manufacturing processes, mass transfer operations between a high viscosity liquid and gases are applied, but mass transfer rates have been explained only using kLa. We measured kL for molten polystyrene and corn syrups by using a rotating cylinder with surface renewal action in which surface area was known. As a result, it is proved that (1) kL between gases and high viscosity liquids are expressed by Hibgie’s penetration theory, and (2) diffusivities are obtained from measurements of kL in corn syrup-CO2 and glycerine-CO2 systems.
