What is mass transfer ?
The transport of one constituent from a region of higher concentration to that of a lower concentration.Mass transfer occurs when a component in a mixture migrates in the same phase or from phase to phase because of a concentration difference between 2 point.
Mass transfer is also very important in bio-separations, biomedicine, drug delivery, artificial organ, etc
General Molecular Transport Equation for Momentum, Heat and Mass Transfer
Driving force for mass transfer stands for gradient concentration.
Examples of Mass Transfer Phenomena
- A drop of blue liquid dye is added to a cup of water
clear fluid + red dye = pink water
- Sugar in a cup of coffee dissolves and diffuses to the surrounding solution
- In a fermentation process, nutrients and oxygen dissolved in the solution diffuse to the microorganism
- In a catalytic reaction, reactants diffuse from the surrounding medium to the catalysts surface where reaction occurs.
