Introduction At the very heart of chemical engineering lies the discipline of transport phenomena, a subject that unifies the principles of momentum transfer (fluid mechanics), heat transfer, and mass transfer. These three pillars describe how momentum, energy, and matter move through physical systems. Whether it’s designing a heat exchanger, modeling pollutant diffusion, or … [Read more...]
Mass Transfer: Definition, Types, Equations and Examples
Mass transfer is the transport of a chemical species within a material or between phases. In ordinary diffusion, a species moves from higher to lower concentration. Fluid motion can also carry species and increase transfer rates. Distillation, gas absorption, drying and extraction are important applications in chemical engineering. When sugar spreads through still water, … [Read more...]
