Separation processes refer to the methods used to separate mixtures of substances into their individual components. These processes are important in various industries, such as chemical engineering, food processing, and environmental science. Some common separation processes include distillation, filtration, chromatography, and centrifugation. Distillation involves heating a mixture to separate components based on their boiling points, while filtration uses a porous material to separate solids from liquids. Chromatography separates components based on their affinity for a stationary phase, and centrifugation separates components based on their density differences. Overall, separation processes are essential for purifying substances, isolating specific components, and creating products with desired characteristics.
