Mass transfer coefficient equation. You have a device where a number of system properties can be varied: the surface area for mass transfer, the molar rate of transfer, and the bulk concentration of the species of interest. Feb 2, 2011 ยท The mass transfer coefficients depend on the diffusivity of the solute and the hydrodynamics of the phases. The ‘kL’ represents the rate of molecular diffusion through the gas-liquid interface and the ‘a’ represents the area of this interface per liquid volume [1]. Experimental results also have demonstrated that microscopic-scale eddies can influence te values. It has been shown that kL depends on turbulent intensity, expressed as a function of ε. This will help us to design and optimize chemical engineering mass-transfer units. g. Selection of the most applicable model is dependent on the materials and the system, or environment, being studied. The use of mass transfer coefficient is covered in Chapter 2. Encompasses all mass-transfer mechanisms: random motion, convection, thermodynamics-driven (specific interaction). zodl uaxl pblxshc ls5x ijwpk pvy w7vzk zlhp dvai vx87g
