- 3. + Introduction ◼ What’s mass transfer? ▪ mass transfer refers to the movement of substances from one place to another and plays a fundamental role in various industries and processes.. Chen-331 Application of mass transfer 3
- 4. + Importance of Mass Transfer Chen-331 Application of mass transfer 4 ◼ Importance of Mass Transfer. o Mass Transfer is the Basic Subject of Chemical Engineering. A Chemical Engineer should know that how an operation is taking place for example ammonia dissolves in water we know that but how dissolves? Mass Transfer tells us the mechanisms and Concentrations between different phases.
- 5. + Mass Transfer Mechanisms Chen-331 Application of mass transfer 5 ◼ the three main mass transfer mechanisms. o Diffusion:The movement of molecules from an area of high concentration to low concentration. o Convection:The transfer of mass due to bulk fluid motion. o Mass transfer by reaction: Involves chemical reactions that result in the transfer of mass.
- 6. + Applications in Chemical Engineering Chen-331 Application of mass transfer 6 ▪ Separation processes: Distillation, absorption, extraction, and adsorption. ▪ Reactor design: Mass transfer influences reaction rates and product yields. ▪ Mass transfer in catalysis: Enhancing the efficiency of catalytic reactions. ▪ Crystallization: Controlling crystal size and purity through mass transfer.
- 7. + Environmental Applications Chen-331 Application of mass transfer 7 o Water treatment: Removal of contaminants through processes like filtration and reverse osmosis. o Air pollution control: Mass transfer assists in removing pollutants from flue gases. o Soil remediation: Mass transfer techniques aid in the removal of contaminants from soil.
- 8. + Biomedical Applications Chen-331 Application of mass transfer 8 ▪ Drug delivery systems: Achieving controlled release of medications. ▪ Artificial organs and tissue engineering: Optimizing nutrient and oxygen transport. ▪ Bio separations: Purification of biopharmaceuticals and biomolecules.
- 9. + Mass Transfer in Energy Sector Chen-331 Application of mass transfer 9 ▪ Gas separation: Membrane technology for carbon capture and natural gas processing. ▪ Fuel cells: Mass transfer optimization for efficient electrochemical reactions. ▪ Heat exchangers: Enhancing heat transfer for improved energy efficiency.
- 10. + Conclusion Chen-331 Application of mass transfer 10 o A clear understanding in process chemistry, reaction kinetics, and mass transfer is the essential requirement to achieve the best achievable technology. Many industrial and/or waste treatment processes are involved in diffusion-controlled mechanism.To increase process efficiency and reaction rate, the mass transfer of those processes should be improved, which can be approached by development of prediction model using theoretical theory such as Fick’s law or penetration theory.
