3. Interfacial areas and material transfer coefficients
Table 1 gives an idea of the orders of magnitude of material transfer coefficients, liquid retention rates and interfacial areas obtained in different types of gas-liquid contactors encountered in industry.
First, we'll look at techniques for physically or chemically determining the interfacial area a; then, we'll examine techniques for determining the volume transfer coefficients k L a and kGa.
