Mass Separation: Crash Course Engineering #17
It can be really important to separate out chemicals for all kinds of reasons. Today we’re going over three different processes engineers use to achieve that separation: distillation, which separates substances based on their different boiling points; liquid-liquid extraction, which uses differences in solubility to transfer a contaminant into a solvent; and reverse osmosis, which filters molecules from a solvent by pressurizing it through a semipermeable barrier.
