    Study Notes

    Separation Processes

    • The main goal of purification is to separate mixtures into their pure components, achieving a desired level of purity.

    Vapor Pressure

    • The equilibrium pressure of a vapor above its liquid is the vapor pressure.
    • The vapor pressure of a liquid is the pressure exerted by the vapor when it is in equilibrium with its liquid phase.

    Separation of Mixtures

    • A mixture of methanol and water can be separated into its pure components through separation processes such as distillation, crystallization, or extraction.

    Motivation for Chemical Engineers

    • The main motivation for chemical engineers dealing with separation processes is to produce pure products with desired properties, efficiently and economically.
