2. Thermodynamic Principles
Thermodynamics is the study of energy and its transformations. The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed. The second law of thermodynamics states that the entropy of an isolated system always increases over time.
The third law of thermodynamics states that the entropy of a perfect crystal at absolute zero is zero.
Thermodynamics has many applications to chemical processes. For example, it can be used to calculate the energy requirements of a chemical reaction, to design heat exchangers, and to optimize the efficiency of chemical processes.
Examples of how thermodynamics can be used to solve engineering problems:
- Calculating the energy requirements of a chemical reaction
- Designing heat exchangers
- Optimizing the efficiency of chemical processes

4. Heat Transfer
Heat transfer is the movement of thermal energy from one object to another. The three modes of heat transfer are conduction, convection, and radiation.
Conduction is the transfer of thermal energy through direct contact between two objects. Convection is the transfer of thermal energy by the movement of a fluid. Radiation is the transfer of thermal energy through electromagnetic waves.
Heat transfer has many applications to chemical processes. For example, it can be used to design heat exchangers, boilers, and furnaces.
Factors that affect heat transfer rates:
- Temperature difference between the two objects

Mass transfer is the movement of mass from one location to another. The basic principles of mass transfer include diffusion, convection, and absorption.
Diffusion is the movement of mass due to a concentration gradient. Convection is the movement of mass due to the movement of a fluid. Absorption is the movement of mass from a gas into a liquid or solid.
Mass transfer has many applications to chemical processes. For example, it can be used to design distillation columns, absorbers, and scrubbers.
Factors that affect mass transfer rates:
- Concentration gradient
- Surface area
- Diffusion coefficient
Examples of how mass transfer can be used to design and operate chemical processes:
- Designing distillation columns

- Batch reactors
- Continuous reactors
- Plug flow reactors
- Mixed flow reactors
Applications of chemical reaction engineering:
- Designing reactors for the production of chemicals
- Designing reactors for the production of fuels
- Designing reactors for the production of pharmaceuticals
7. Process Control
Process control is the use of feedback and feedforward control loops to maintain the desired operating conditions of a chemical process. Feedback control loops measure the output of a process and use this information to adjust the input of the process.
Feedforward control loops use information about the disturbances to a process to adjust the input of the process.
Process control has many applications to chemical processes. For example, it can be used to control the temperature, pressure, and flow of a chemical process.
Types of process controllers:
- Proportional controllers
- Integral controllers
- Derivative controllers
- PID controllers
Applications of process control:
- Controlling the temperature of a chemical process
- Controlling the pressure of a chemical process
- Controlling the flow of a chemical process
