Mass Transfer Processes Quiz

Some common examples of mass transfer processes are the evaporation of water from a pond to the atmosphere, the purification of blood in the kidneys and liver, and the distillation of alcohol.

Mass transfer is commonly used in engineering for physical processes that involve diffusive and convective transport of chemical species within physical systems.

Industrial processes involving mass transfer operations include separation of chemical components in distillation columns, absorbers such as scrubbers or stripping, adsorbers such as activated carbon beds, and liquid-liquid extraction.
