    Study Notes

    Mass Balances

    • A mass balance is a fundamental principle in chemical engineering that accounts for the amount of mass entering and leaving a system.
    • The law of conservation of mass states that mass cannot be created or destroyed, only converted from one substance to another.
    • Mass balance equations are used to calculate the amount of material entering and leaving a process, and to identify any losses or gains.

    Energy Balances

    • Energy balances are used to account for the energy entering and leaving a system.
    • The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
    • Energy balance equations are used to calculate the amount of energy required for a process, and to identify any energy losses or gains.

    Stoichiometry

    • Stoichiometry is the study of the quantitative relationships between reactants and products in a chemical reaction.
    • Stoichiometric coefficients are used to balance chemical equations and to calculate the amount of reactants required and products formed.
    • Limiting reactants and excess reactants are important concepts in stoichiometry, as they determine the amount of product formed.

    Reaction Kinetics

    • Reaction kinetics is the study of the rates of chemical reactions.
    • The rate of reaction is influenced by factors such as concentration, temperature, and catalysts.
    • Rate equations are used to model the kinetics of a reaction, and to determine the rate constant and activation energy.

    Process Flow Diagrams (PFDs)

    • PFDs are visual representations of a process, showing the flow of materials and energy through the system.
    • PFDs are used to design and optimize processes, and to identify potential problems and bottlenecks.
    • PFDs typically include symbols and notation to represent different components, such as reactors, tanks, and pumps.

    Process Control

    • Process control is the use of sensors, actuators, and control algorithms to regulate a process and maintain desired conditions.
    • Feedback control, feedforward control, and cascade control are common control strategies used in chemical engineering.
    • Process control is critical to ensure safe and efficient operation of a process.

    Separation Technologies

    • Separation technologies are used to separate components of a mixture based on their physical and chemical properties.
    • Common separation technologies include distillation, crystallization, filtration, and chromatography.
    • Separation technologies are critical in chemical engineering, as they are used to purify products and recover valuable components.

    Transport Phenomena

    • Transport phenomena are the study of the transfer of mass, momentum, and energy between systems.
    • The three main transport phenomena are heat transfer, mass transfer, and momentum transfer.
    • Understanding transport phenomena is critical in chemical engineering, as they are used to design and optimize processes.

    Mass Balances

    • Mass balance accounts for the amount of mass entering and leaving a system, based on the law of conservation of mass that states mass cannot be created or destroyed, only converted from one substance to another.
